The hydrocyclone separator is an effective mineral processing equipment for ore classification. The pulp is sent into the hydrocyclone separator along the tangent direction at a certain speed to rotate. Under the action of centrifugal force, the coarser particles are thrown to the wall of the hydrocyclone separator, moving downward in a spiral trajectory, and are discharged into coarser products from the settling nozzle. The fine particles and most of the water is discharged from the overflow pipe in an internal spiral trajectory, thus achieving the purposes of separation and classification.

In the production, the factors affecting the working efficiency of the hydrocyclone separator mainly include ore properties, equipment structure, and technological operation. Next, we will explain to you how these various factors affect the working efficiency of the hydrocyclone separator.

The higher the ore density, the finer the grading granularity. When the pulp concentration is large and the mud content is high, its viscosity and density increase correspondingly, which increases the movement resistance of the particles, and makes the grading granularity coarser. Therefore, it is necessary to complete the pre-desliming when the mud content is high. The suitable pulp concentration is usually determined by the mineral processing test according to the specific situation.

In terms of equipment structure, the factors that affect the working efficiency of hydrocyclone separator mainly include diameter and height of the cylinder, size of the feeding port, the diameter of the settling nozzle, diameter and depth of the overflow pipe, and the size of the cone angle.

The diameter and height of the cylinder have a certain relationship with the size of other parts, and it determines the separation size and production capacity of the hydrocyclone separator. When the ratio among the feed pressure, feeding port, overflow port and the diameter of the hydrocyclone separator remains constant, the production capacity of the hydrocyclone increases with the increasing diameter of the hydrocyclone separator, and the separation size also becomes coarser with the increasing diameter of the hydrocyclone separator.

The height of the cylinder mainly affects the time length of centrifugal force that the pulp is affected, thus influencing the working efficiency of the hydrocyclone separator. In general, the height of the cylinder should be 0.6-1.0 times of its diameter. The higher the cylinder height is, the finer the separation size is. However, if it exceeds a certain limit, it will lose its function due to the increasing of the ore feeding pressure.

The size of the feeding port will affect the working efficiency and production capacity of the hydrocyclone separator. Too large or too small feeding port is not conducive to the classification effect of the hydrocyclone separator. If the ore feeding size is coarser and the ore feeding pressure is lower, the ratio between the ore feeding port and the diameter of the hydrocyclone can be slightly larger (generally 0.16-0.20). However, when the ore feeding size is fine and the ore feeding pressure is high, the ratio between the ore feeding port and the diameter of the hydrocyclone is usually maintained at 0.14-0.16.

Usually, the diameter of the settling nozzle is large, the overflow flow is small, the overflow size becomes fine, while the settling amount increases, the concentration becomes low and the fine particles increase, but there is no obvious effect on the processing capacity of the hydrocyclone separator.

The diameter of the settling nozzle is small, the concentration of the settling is high, the discharge of the settling is reduced, and there is some coarse size in the overflow. Too small diameter will make the coarse grains accumulate more and more in the top of the cone, causing the blockage phenomenon.

The appropriate diameter of the settling nozzle should make the settling discharge in an umbrella shape, the included angle should be 40-70. The diameter ratio of the settling nozzle and the overflow pipe is generally 0.4-0.8.

The diameter of the overflow pipe should be proportional to the diameter of the hydrocyclone separator. The diameter of the overflow pipe increases, the overflow flow increases correspondingly, the overflow particle size becomes coarser, and the fine particle size in the settling sand decreases, the settling sand concentration increases, and the classification efficiency of the hydrocyclone decreases. In addition, the ratio between the depth of the overflow pipe and the height of the hydrocyclone cylinder should be maintained at 0.7-0.8. Too deep or too shallow depth will make the overflow grain size become coarser, and increase the content of fine grains in the settling sand, thus affecting the working efficiency of the hydrocyclone separator.

The size of cone angle has an important effect on the working efficiency of hydrocyclone. Small cone angle, long cone (large distance between overflow port and settling port) can increase the classifying volume, and strengthen the classification process of ore particles in the hydrocyclone separator, which is conducive to the separation of fine materials. The cone angle is generally 10-15 for the desliming of fine grains, and 20-45 for the classifying of the coarse grain grading.

In the production, the technological operation affecting the working efficiency of the hydrocyclone mainly includes ore feeding, overflow and discharge of settling sand, which requires the hydrocyclone operators to improve their skills in the production process, keep the technological parameters within a reasonable range, thus ensuring the stable operation of hydrocyclone separator.

The ore feeding pressure mainly affects the processing capacity of hydrocyclone and classifying size. With the increase of ore feed pressure, the slurry velocity is accelerated, the viscosity effect is reduced, and the classification effect of hydrocyclone is improved. Most concentrators adopt the low pressure (49-98KPa) for the treatment of coarse-grained materials, and the high pressure (98-294KPa) for the treatment of fine and muddy materials.

The feed concentration and size composition will directly affect the concentration and particle size of the final product. The coarser the classifying size is, the more mud or fine particle size in the classifying material is, the higher the feed concentration should be, the higher the slurry viscosity is and the coarser the particle size of the overflow product is.

The ideal working state of the hydrocyclone is that the settling sand is ejected in umbrella shape. Therefore, the angle of the umbrella should not be too large, so that it is appropriate to just spread out. When used for the concentration operation, the settling sand is discharged in a rope shape with a higher concentration. When used for dehydration operation, the settling sand is discharged in a larger umbrella shape with the least solid content in the overflow.

These are the three factors that affect the working efficiency of the hydrocyclone separator. It is worth noting that maintaining the working efficiency of the hydrocyclone is a systematic project, and all factors are interrelated with each other. Each concentrator must take all things into consideration for obtaining the ideal working efficiency of the hydrocyclone separator.

At present, there are about 300 kinds of iron-bearing minerals found in nature. According to their chemical composition, iron ore can be divided into magnetite, hematite, limonite and siderite; The specific magnetic susceptibility of the material is different, and iron ore is divided into strong magnetic and weak magnetic minerals, which also provides a basis for the selection. The beneficiation process of iron ore of different nature is also completely different.

Multimetal-containing magnetite gangue minerals often contain silicate and carbonate minerals, cobalt pyrite, chalcopyrite or apatite, etc. It is recommended to use a combined weak magnetic separation-flotation process, that is, use weak magnetic separation The process first recovers iron, and then uses the flotation process to recover sulfide or apatite, which is conducive to obtaining higher beneficiation indexes.

Generally, the combined process of weak magnetic separation and flotation is also divided into two types: weak magnetic separation-flotation and flotation-weak magnetic separation. The difference between these two processes lies in the destination of the conjoined magnetite and sulfide.

This shows that under the same grinding particle size, the combined process of flotation and magnetic separation can obtain iron concentrates with low sulfide content and sulfide concentrates with high recovery rate.

Single weakly magnetic iron ore mainly includes hematite, siderite, limonite, and hematite (spiegelite)-siderite ore. Due to the variety of minerals involved in this kind of minerals and a wide range of particle sizes, the beneficiation method will be more complicated, often using gravity separation, flotation, strong magnetic separation or their combined processes.

The flotation process is mainly used for the separation of fine-grained and particulate weakly magnetic iron ore, including two process flows of positive flotation and reverse flotation. Among them, the positive flotation process is suitable for quartz hematite ore without easy pumice gangue, and the reverse flotation process is suitable for ore with easy flotation gangue.

However, due to the low grade of strong magnetic separation concentrates of most weak magnetic iron ore, and the low processing capacity of the gravity separation process unit, the combined process of strong magnetic separation and gravity separation is often used, that is, the strong magnetic separation process is first used to discard a large amount of waste. Qualified tailings, and then use the gravity separation process to further process the strong magnetic concentrate to improve the grade of the concentrate.

Polymetallic weakly magnetic iron ore refers to phosphorus-containing hematite and siderite ore. Most concentrators will first use gravity separation, flotation, strong magnetic separation or a combined process to recover iron minerals, and then use the flotation process to recover phosphorus or sulfide.

It is not difficult to see that due to the large variety and complex nature, most iron ore will use multiple combined beneficiation processes to obtain ideal beneficiation indicators. It is recommended that mine owners must do a good job of beneficiation tests, and rationally choose the appropriate iron ore beneficiation process based on the final report results.

Hydrocyclone separators are used worldwide in the mining and mineral processing industries for classification, de-sliming and de-watering applications. The main purpose is to separate a stream of particles into different size fractions. However, there are also applications where a fine slime fraction requires removal or where the solids need to be dewatered as much as possible. Hydrocyclones are also used in other industries like manufacturing, food processing, construction (aggregate) and wastewater management.

Multotecs hydrocyclone separators offer improved efficiency, increased longevity and reduced energy requirements. These inherent values have been gained through optimising our hydrocyclones over hundreds of plants and jobsites throughout the world, and intensive R&D.

Benefits of Multotecs range of hydrocyclones include precise cut points in your slurry, improved capacity and reduced wear rates with Multotecs scrolled evolute design. Some of the product features are:

We manufacture complete ranges of off-the-shelf cyclone separators and customised solutions too. This ensures that our recommended solution matches your specific process requirements. We also manufacture cyclone distributors that support up to 62 cyclone separators.

The hydrocyclone separator is simplistic in design that uses pressure created by a centrifugal pump or hydrostatic head to generate centrifugal force and flow patterns within the hydrocyclone. It does not have any moving parts, but consists of an inlet section, vortex finder, cylindrical section, a conical section, an underflow spigot section and an overflow pipe. While the primary design of the hydrocyclone remains the same regardless of the industry, there are differences in the cyclones size and configuration depending on the application requirements. The combination of centrifugal force and drag force creates separation within a liquid medium which serves as the transport medium. Larger diameter particles separate easier compared to smaller diameter particles. The hydrocyclone is sometimes referred to as a hydrocyclone centrifugal separator due to the centrifugal forces that forms within the unit. Depending on the industry and application requirements, hydrocyclones are sometimes referred to as a hydrocyclone sand separator and, in the construction aggregate industry a desliming hydrocyclone is a common term. Where the hydrocyclone is used for dewatering purposes, it can also be called a hydrocyclone separator or hydrocyclone stacker. Designed for effective separation For hydrocyclone separation to be effective, the cyclone must be installed vertically, with the sedimentation tank placed directly under the cyclone. There are however applications where the cyclone can be installed at an angle, but this will be to reach specific objectives like a coarser cut point or more consistent underflow densities. The conical shape speeds up the velocity of the water, which in turn increases the centrifugal forces which results in maximising separation efficiency. Multotec developed the scrolled evolute design, which offers much higher capacity when compared to the standard tangential and involute inlet designs. The unique scrolled evolute design maximises the hydrocyclone separation efficiency while lowering operating costs. Vortex finder wear, a problem experienced on earlier designs, is eliminated with the scrolled evolute inlet design. The Multotec hydrocyclone separator range consists of cyclone diameters ranging from 25mm to 1400mm, allowing them to accommodate a range of volumetric flow rates and cut size requirements. Different vortex finders, cone angles and spigot diameters are standard for all diameters. Hydrocyclones up to 100 mm (small diameter hydrocyclone) are manufactured mainly from polyurethane. Larger cyclone separators can be supplied as steel polyurethane lined units, steel ceramic or silicon carbide lined units or steel rubberlined units where the rubber liners can be either vulcanised or fitted with loose rubber liners.

Cyclone separators work on the principle of inertia to separate matter. Hydrocyclones are specially designed to provide an environment where centrifugal force can be harnessed to separate matter based on size and density.

The volumetric flow rate that must be processed, solids feed rate, solids feed concentration, the feed size distribution of the solids feed, the required duty of the hydrocyclone and expected cut point are some of the factors that must be considered. In cyclone selection, considering the optimal cyclone diameter, cyclone configuration like the cone angle and vortex finder to maximise separation efficiency, minimise operating cost and minimise energy requirements is important.

Once the hydrocyclone is operational, any significant changes in operating conditions can be accommodated via vortex finder and spigot diameter changes. Seldom will a different cyclone diameter be required.

In a hydrocyclone, cut size is the separation point between particles deemed to be coarse and fine. If a particle is at the cut point size, it will have a 50% chance of reporting to either the overflow or underflow.

A vortex finder is a small pipe that extends from the overflow discharge section of a hydrocyclone into the body. Its main purpose is to prevent incoming material from short circuiting the classification process, which in turn leads to reduced separation efficiencies.

Full technical support and field service, together with high availability of cyclone spare parts and accessories helps ensure maximum plant performance. We manufacture cyclone distributors supporting up to 62 cyclones.

The Multotec hydrocyclone technology range comprises cyclone diameters from 25 to 1 400 mm. Most of these diameters can accommodate a range of cone angles, while different vortex finders and spigot diameters are standard for all diameters.

Small diameter cyclones (up to 100 mm) are manufactured mainly from polyurethane, while larger cyclones can be polyurethane, steel cyclones with bonded or loose rubber lining, and steel with ceramic lining.

The scrolled evolute and ribbon inlet cyclone designs have a much higher capacity compared to standard inlet designs. The result is that vortex finder wear is substantially reduced, thereby lowering operating costs while maximising hydrocyclone separation efficiency.

If the hydrocyclone liner becomes damaged, the material which finds its way between the liner and the cyclone shell will begin to drain from weep holes, indicating that the liner needs to be replaced. With better insight into the state of your hydrocylone liner, you can reduce unplanned stoppages and downtime, and extend the life of the cyclones steel shells.

To improve cyclone component wear characteristics, and to ensure they can be used in highly aggressive applications, Multotec has been developing and supplying SiC (Silicon Carbide) lined cyclones and components, with all trial applications have showing excellent results. This ensures that gaps between tiles are minimised, meaning less epoxy, which wears faster than tiles, is used.

Highly abrasive slurry? Multotec uses engineered ceramic tiles to provide a longer-lasting wear life of the surface. Engineered tiles are pressed with chamfered sides and then cut precisely to the desired shape.

Each tile is specifically designed for its place in the complete tile kit, ensuring a very tight fit with a minimum of space at the joints. Tile widths are selected to provide a smooth internal surface.

Cyclones are selected and sized by Multotecs experienced process team using our specialised CY-i cyclone sizing software to achieve optimum centrifugal forces and cut points to best suit your precise requirements. For specialised applications Multotec can custom design and manufacture a cyclone to meet your application.

Cyclones need to be correctly maintained to ensure they operate at peak separation efficiency. Your local Multotec branch will help apply sound operating and maintenance procedures for your cyclones to help ensure they reliably deliver your required cut points to meet your process parameters.

Maintenance should preferably be done on every maintenance shutdown in order to allow for internal inspection. Your local Multotec service crew will provide end-to-end cyclone inspections and servicing, which includes:

With the Multotec pressure gauge installed on your cyclones, plant operators will be quickly notified if there is any surging or pressure drop in the hydrocyclone feed stream. The reading on the pressure gauge will allow for an accurate calculation of volumetric flow rates to the cyclone which will make it possible to calculate the mass flow rate.

Lower cyclone pressure results in inefficiencies while high pressure increases the centrifugal force beyond its design specifications, which increases cyclone wear rate. Ensuring your cyclone operates in the optimum pressure range helps reduce costly potential downtime, and improves downstream processing performance.

Multotec has developed the Internal Surface Photographic Inspection (iSpi) system for cyclones. By making use of a 360 camera, our application engineers are able to offer a system which enables them inspect the inside of a customers cyclone in-situ and with minimal effort.

A hydrocyclone separator is a piece of equipment used to classify particles according to their size and density. Hydrocyclones have no moving parts; instead they are shaped like a cone to produce a vortex when slurry is fed into the cyclone. In generating sufficient centrifugal force, this vortex allows coarser and finer particles to separate. Coarser particle will exit the cyclone through the underflow discharge, while finer particles will be discharged via the overflow discharge.

The point of separation between coarse and fine particles is called the cut point. A number of factors must be considered when defining this cut point. Size and cone angle of the cyclone; the velocity and angle of the feed; as well as the specific slurry characteristics all play a role in determining how the vortex will develop in the cyclone. Once the vortex is established, the vortex finder is configured to the required point of particle separation.

In a hydrocyclone, cut size is the separation point between particles deemed to be coarse and fine. If a particle is at the cut size, it will have a 50% chance of reporting to either the overflow or underflow. Any particle size greater than the cut size will exit via the underflow (coarse particles), while particles less than the cut size (fine particles) will be discharged via the overflow.

To produce a particular cut size from a cyclone, engineers must consider velocity and angle of slurry feed, cone angle and cyclone diameter, and position of the vortex finder, which is a short pipe that extends from the overflow discharge into the cyclones vortex.

A dewatering cyclone, used for solid-liquid separation, operates in the same principle as a conventional cyclone. Feeding slurry at high velocity into a cone shape generates centrifugal force and solid particles inside the slurry begin to separate according to size and density. In this way, suspended solids can be removed from ballast waters.

Hydrocyclones are an excellent dewatering solution because of their low-cost, low-maintenance design. Multotec dewatering cyclones are ideal for a range of applications in solids dewatering, water recovery and densification applications.

A hydrocyclone is used to separate particles in liquid. They are used in industries such as mining, minerals processing and aggregates to classify, densify, dewater, de-slime and recover fines. They are specially designed to provide an environment where centrifugal force can be harnessed to separate matter based on size and density.

A vortex finder is a small pipe that extends from the overflow discharge section into the body. It provides the channel that will separate the fine material from higher mass particles. It is sized and positioned within the body of the cyclone to produce your exact cut point.

Hydrocyclones, or more simply Cyclones, and variations such as McLanahan Separators are used in a variety of applications, including classification, desliming, fines recovery, densifying and dewatering.

They can be used in industries such as sand, aggregates, coal, industrial minerals, hard rock mining and more. Hydrocyclones were invented in the late 1800s and became widely used in mineral processing because they are relatively inexpensive, process high volumes, take up minimal floor space and have no moving parts.

Hydrocyclones are exceptionally simple machines but require process knowledge to be utilized properly. Although there are many configurations, most Hydrocyclones have a cylindrical upper (feed) section, with either a tangential or involute style feed inlet, followed by lower conical sections ending with the apex. Designs that combine rubber-lined, bolt-together sections makes them simple to operate and maintain. Alternative linings, such as polyurethanes and ceramics, are also available.

While Cyclones are simple to operate, a great deal of understanding is needed to apply this technology to any given application. Whether the application is sand-washing or classifying high-end minerals, McLanahans process engineers have long experience in successfully applying this product into stand-alone applications and integrated systems. With our in-house developed simulations, we can reliably predict outcomes of different scenarios to evaluate new or existing installations. Using the application predictions and the "been there, done that" experience, McLanahan personnel can develop the best approach to any process requirements.

Slurry enters the feed inlet at a designated pressure and volume. Independent of the shape or configuration of the inlet, slurry follows the fall of the upper cylinder in a rotating action. Resultant centrifugal forces send coarser material to the outer wall to travel downward and be further accelerated in the conical sections. These coarser fractions then exit through the apex, or spigot, at the bottom of the Hydrocyclone. Finer fractions remain rotating with the fluid in the inner core and are removed upward by an air core.

The air core is formed at the spigot/apex as air is drawn in to the Hydrocyclone. The vortex finder provides a pathway for the air to exit the body of the Hydrocyclone. As the air flows through the vortex finder, the fluids and finer fractions are dragged along to perform the classification of materials. The air core is important for the proper operation of the cyclone. If the air core is not formed due to excessive solids discharge, called roping, the cyclone will not efficiently classify the slurry. The apex/spigot is sized for the expect range of solids. Significant process changes may require a resizing in the spigot/apex.

McLanahan has collected field data from hundreds of applications, allowing process engineers to make the accurate selection of size and configuration for each application using computer simulations. Performance is influenced by the size of the unit and itsoperating pressure, as well as theinlet area, vortex finder diameter, underflow and overflow diameters, cylindrical sections and cone angle.

Hydrocyclones are commonly used for desliming, dewatering and sizing -4mesh (5mm) particles. The use of Hydrocyclones in washing and stockpiling is common in the construction aggregate industry. Desliming prior to Classification Tanks and Screw Washers can significantly improve theperformance of these devices in high fines situations. Separators provide consistent density feed to Attrition Cells in Frac Sand.

For mineral applications such as in hard rock and precious metals processing, Cyclones are the most common equipment to control what size of materials exit the comminution (ball milling) circuit. In these applications, it is the fine fraction in the overflow that is the product. Different ores have different liberation sizes, so Hydrocyclones are configured in many different ways.

Alternative linings, such as polyurethanes and ceramics, are available for different chemistries (such as where amines are present) and forhandling highly abrasive materials. Hydrocyclones can also be made from cast hard metals such as ni-hard and hi-chrome. These designs are often used in processes known as heavy media for coal and iron ore, etc.

Hydrocyclones also find use in pharmaceuticals; agricultural applications, such as sand/manure separation; pulp and paper; potable water and wastewater treatment systems; degritting of spray water; etc.

In Aggregate applications, typical recovery of 2.7 specific gravityparticles is +200 mesh (75m) at 2.7 SG; in typical Fines Recovery applications, Hydrocyclones capture down to 400 mesh (38m) at 2.7 SG; and in specialty applications, recoveries are possible down to 625 mesh (20m) at 2.7 SG.

Hydrocyclones are ideal for recovering down to 400 mesh (38m) particles of 2.7 SG. This is typicallydone in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38m) and a product discharging the screen in a drip-free, readily conveyable and stackable form. McLanahan uses 9 and 12 Hydrocyclones for this application in place of 4 units. Wepreviously used 4 Hydrocyclones in our systems, but we found them to be plagued with blockages in the apexes of the Hydrocyclones, resulting in significant amounts of unprocessed materials. We have also replaced many clusters of competitive-brand small Cyclones with 9 and 12 units with the benefit of low blockage rates and longer life with very similar performance.

Hydrocyclones are limited in being able to dewater fine solids to a conveyable state. The finer the underflow solids, the more dilute it will be; therefore, Dewatering Screens are used to further dewater Hydrocyclone underflow.

Hydrocyclones and Separators are selected based on several parameters, including volume of flow, tons per hourof recoverable material andcut-point required. Larger units process higher volumes; however, the larger the Hydrocyclone, the coarser the cut. Therefore, processing a larger volume of slurry with the need to recover finer fractions would lead to the selection of several smaller units.

The leader in creating complete processing plants to produce frac sand needed in the oil and gas well drilling industry, McLanahans Frac Sand Plants are designed to remove clay impurities, as well as size and dewater sand. McLanahan process engineers work directly with customers to determine layout and equipment requirements for each deposits unique characteristics. Utilizing proven technologies, plants are engineered with the right equipment to meet each producers needs, including: centrifugal slurry pumps, Hydrocyclones and Separators, Dewatering Screens, Fine Material Screw Washers, Hydrosizers, Attrition Scrubbers, Thickeners, and Filter Presses.

Hydrocyclones first appeared in dutch in the late 1800s, Hidrociclon is an equipment that uses rotary current to classify, separate or sort coarse particles of sewage. It widely used in mine processing such as aggregates, hard rock mining, sand, industrial minerals, coal and more. Because the equipment without moving parts, take up small areas, process high volumes and relatively cheap.

The shortened form(often referred to) of hydrocyclone is a cyclone. There are two types of pressure and gravity. The water depends on pressure or gravity feed into from overflow, Then under the action of centrifugal force, the coarse and heavy granular materials are thrown towards the wall and rotated downward, and discharge together with the formed concentrated liquid. The smaller materials were discharged after rotating again.

Under the action of pressure, the ore slurry enters the shell along the tangent direction of the pillar body. And rotates in the hydrocyclone shell. The coarse particles (or the dense particles) enter the periphery of rotary current due to them get the larger centrifugal force. At the same time, the coarse particles downward flow with ore slurry. Finally, discharged from the bottom sand nozzle into the sand. The fine particles are in the center of the rotary flow because they suffer less centrifugal force. And moving up with the liquid, then the overflow discharge from the downspout.

Hydrocyclone is a grading device that uses centrifugal force to accelerate ore particle deposition. It needs the pressure to feed ore, so it consumes a lot of power but occupies a small area, cheap, the processing capacity is large, The classification efficiency is high, obtain very fine overflow product, mostly used in the second stage of closed-circuit grinding classification equipment.

Heavy medium cyclone is a common heavy medium separation equipment. As grading equipment in the grinding circuit, especially as fine grinding grading equipment. Slurry will be desliming, concentration.

The upper part of the Hydrocyclone is a hollow cylinder, and the lower part is an inverted cone connected with the cylinder. The two constitute Hydrocyclone Simple operation. The upper end of the cylindrical cylinder is provided with a feed pipe tangentially, and the top is provided with an overflow pipe and an overflow pipe. There is a sinkhole at the bottom of the cone. The parts are connected with flange plates and screws. There are usually lined with rubber, polyurethane, silicon carbide or gloss Greenstone castings in feed port, cylinder and sand mouth, it can reduce wear and replace after wear.

The separation of the mixture under high-speed rotation is realized by using strong centrifugal force. For example, the classic static Hydrocyclone to push the feed mixture into the cyclone at relatively high speed uses external pressure. the mixture moves along the tangential direction of the Hydrocyclone, it will cause the liquid to rotate along the cylinder wall, this motion is generally referred to as the outer swirl.

The particles in the outer swirl are subjected to Centrifugal Force. If their density is greater than the density of the surrounding liquid, the centrifugal force on them will become larger and larger. The particles overcome this resistance and move toward the wall, separating from the surrounding liquid once centrifugal force is greater than the liquid resistance due to motion. The particles that arrive near the wall are pushed by the liquid above the hydrocyclone and move down the wall. It reaches the underflow port and collects to form a suspension with a high thickening degree, which is discharged from the underflow port.

The liquid after separation to rotate downward continue move, entering the cone section, because the inner diameter of the liquid separator gradually reduces, the liquid rotation speed speeds up. Due to the uneven pressure distribution along the radial direction, the closer the liquid is to the axis, the smaller it is and the closer it is to the axis, it becomes a low-pressure area or even a vacuum area, which causes the liquid to move along the Axis.

At the same time, the bottom flow port of the cyclone separator is greatly reduced, the liquid can not be discharged quickly from the bottom flow port, and the overflow port in the center of the top cover of the cyclone cavity moves part of the liquid toward it because it is in the low-pressure zone, thus forming the upward rotating movement And exit through the spillway.

The hydrocyclone takes water as medium to classify and separate mineral particles in the centrifugal force field with tens to hundreds of times acceleration of gravity. According to its different application, it can be divided into grinding classification hydrocyclone, ultrafine classification hydrocyclone, desliming hydrocyclone, concentrated hydrocyclone and so on.

Hydraulic cyclone has the features like low equipment cost, easy assembling and dismantling, convenient maintenance, small floor space required, low capital expenditure, large processing capacity of unit volume, fine classifying grain size, high classifying efficiency, small quantity and short time of staying of the ore pulp in the cyclone, and easy operation of shutdown.

Used for classifying the ore pulp in the grinding loop. A combined unit is usually selected by connecting several units of cyclone in parallel. Its classifying fineness and processing capacity are greatly affected by the diameter of upper cylinder, pressure at the inlet of ore pulp, and the concentration of ore pulp. Therefore, it has a large fluctuation of process.
