Rotary Drum Dryer Working Principle: Wet material goes into the feeding hopper by belt conveyor or bucket elevator, then through the feeder goes into the feed pipe. The feed pipe slope is greater than the natural inclination of the materials, so that the material can inflow the rotary dryer smoothly. There is one hot air furnace supply the hot flue gas for the rotary dryer usually. The fuel can be waste wood, coal, natural gas, diesel, etc. The rotarydryer cylinder is tilted slightly compared with horizontal. Materials and hot flue gas goes into the rotary dryer cilinder from the higher end. During the rotation of the cylinder, the material by gravity goes into the lower end. When the wet material is in the process of moving forward in the rotarydryer cylinder body, the lifting plates inside the rotary dryer cilinder makes the material up and down to contact with the hot flue gas completely. Thus, the moisture inside the wet material is evaporated into water vapour, and finally we get the dried materials. There is one high pressure induced draft fan is used to suck out the water vapour out of the rotarydryer during the drying process. Finally the water vapour with some dust goes into the cyclone dust collector. In the cyclone dust collector, the dust is seperated from the water vapour and falls down from the bottom of the cyclone dust collector; the water vapour leaves the cyclone dust collector from the top pipe of the cyclone dust collector, and finally goes into atmosphere through the chimney. At the end of the rotary dryer, using one belt conveyor to transport the dried material into trucks or storage room directly. The rotary drum dryer seems very simple, but in fact it is one whole drying system, and the drying system should be designed according to: --- The features of raw material, for example the wet sand has surface water which is easier to be dried, but the wood chips has inner water which is more difficult to be dried. ---Initial moisture content(%) of the wet material. ---Output moisture content(%)the dried material needed. ---Bulk density (kg per cubic meter) of the wet material. ---Input capacity (ton per hour). ---Output capacity(ton per hour). ---Fuel Choice such as coal, waste wood, natural gas, diesel, etc. ---End use of the dried product.

rotary drum drying machine

rotary drum drying machine

Rotary drum dryer is one of the traditional drying equipment, and it has reliable running, flexible operation, strong adaptability, and high production capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin and sugar. Its diameter is 1000 4000, and the length is depended on the dry requirements. In the center of the rotary drum dryer, increasing the dispersion mechanism can be avoided; The wet material entering into the drying cylinder is repeatedly copied and left off by the copying plate on the cylinder wall, then in the process of falling, the material is broken into fine particles by dispersator. In this way, the contact area increases greatly, and the material fully contact with the hot air, thus the effect of drying is achieved.

The rotary drum dryer is mainly composed of rotary body, lifting blade, transmission device, supporting device and sealing ring. Dry wet materials are sent to hopper by belt conveyor or bucket elevator, and then by hopper feeder the material enters the feeding end through the feeding tube. The slant of the feeding pipe is larger than the natural inclination of the material, so that the material flows into the dryer smoothly. The cylinder of dryer is a rotating cylinder slightly tilted to the horizontal line. The material is added from the higher end, the heat carrier is entered at the low end with the material in reverse contact; there are also heat carriers and materials that flow into the tube together. With the rotation of the cylinder the material is operated by gravity to the lower end. In the process of moving forward, the wet materials can be directly or indirectly heated by the heat carriers, so that the wet materials can be dried and then be sent out by belt conveyor or spiral conveyor to the discharge end.

rotary dryer with electric lump breaker | criox system

rotary dryer with electric lump breaker | criox system

Completely removes all types of solvents and crushes any residual lumps. A mix of power and intelligence to ensure maximum quality and productivity. CRIOX System, a milestone of Italvacuum product range. Italvacuum, a global manufacturer of vacuum pumps and vacuum dryers for the chemical, pharmaceutical and cosmetics industries.

CRIOX System, the ideal double-cone rotary vacuum dryer/powderer for drying humid material after centrifugation or filtering processes. Double-cone revolving chamber, but not only: with a pair of powerful lump breakers CRIOX System breaks down any product build-up to deliver dry powder ready for sieving and bagging.

CRIOX System is versatile and profitable, as it drastically reduces downtime for line retooling, cleaning and system inspection prior to product change. Thus, swift transition between product campaigns is assured.

From supporting structure to the tiniest detail: all about CRIOX System is conceived to ensure best results throughout the entire production process. Starting from the shape of the central body: the rotary double-cone chamber features smooth lines to enhance full and continuous revolving of the material to be dried, coupled to homogeneous and uniform mixing. Moreover, the adjustable chamber rotating speed allows agitation rates from delicate to moderate.

With its two sets of electric lump breaker blades inside the rotary double-cone chamber, CRIOX System guarantees the best possible result. An exclusive feature that drastically increases the product surface exposed to evaporation and enhances system mixing effectiveness. Thanks to the chamber rotation, each lump-breaker set alternatively goes in and out the product, promoting self-cleaning when emerging. Blade action features two important benefits: prevents product agglomeration and allows grinding and pulverizing of drying mass during the final phase of the process, thereby minimizing subsequent mill intervention. This results in a bulk product ready for bagging or a powder with controlled grain size, thus reducing subsequent processing to only simple sieving. Acting on the core of the product to be dried, the lump breakers significantly reduce drying time, assuring the lowest possible residual humidity, often unattainable with other systems. They also allow operation at lower processing temperatures, preventing downgrading of the most delicate thermo sensitive products. Lump breakers shafting includes fluxed mechanical double sealing, designed to ensure vacuum tightness and absolute cleanliness of dried batch.

Lump breakers are electrically operated. CRIOX System is the only rotary double cone dryer of this type currently on the market. This is a crucial feature, as electric motor-driven lump breakers offer exclusive performance and benefits, including:

The total absence of pneumatic circuits avoids the risk of lubricated air pressure release inside the drying chamber and surrounding environment, thereby ensuring utmost safety throughout the production process and the highest quality of dried material.

Special filtering systems installed directly inside the chamber are available to cover all processing requirements: sintered metal or PTFE cartridge type filters suitable for trapping very fine powders, whose effectiveness during the process is ensured by an automatic nitrogen back-washing system.

From the experience acquired in the optimization of the drying process, Italvacuum suggests also the use of a heated external safety cyclone filter, designed to avoid pressure losses and condensation phenomena, for a complete protection of the vacuum line.

Standard version CRIOX System parts in contact with the product are made of AISI 316L (1.4404) stainless steel. Other weld materials including ALLOY C-22 (2.4602) and AISI 904L (1.4539) are available on request.

CRIOX System special shape is also suitable for fluoro-polymer film internally coated versions which are highly resistant to products containing aggressively corrosive substances (both acids and bases).

Encouraged by the success of these versions, Italvacuum has moved on to produce enameled drying chamber versions, in which the alkaline borosilicate enamel layer, deposited on the steel shell, makes the CRIOX System interior chemically inert. On these versions the lump breaker blades are made of ALLOY C-22 (2.4602) or other process-compatible materials.

CRIOX System is designed and built for quick and thorough cleaning. An important feature for any machine, but crucial for a dryer elected by customers all over the world on account of its versatility and suitability to multi-product processing. Cleanability means easy and simple interior washing, removal of internal components, inspection and external cleaning.

Quick and effective washing is a designed-in feature of CRIOX System. With drying chamber rotation and lump breakers action very few rinses and only small amounts of liquid are sufficient to meet the FDA residual ppm value requirements for acceptable system cleanliness. Guaranteed efficiency and speed, but also very low consumption of rinse liquid to be disposed.

Furthermore, to facilitate SWAB testing as required by FDA for validation of cleaning procedures, Italvacuum has designed and patented a large hatch giving full access to the machine and allowing all necessary operations in total ease and safety.

The sealed external cladding (particle-free configuration), covering the insulation, the electrical hydraulic and pneumatic circuits, makes external cleaning very easy and effective, avoiding product deposits in nooks and crannies.

Partitioning solution allows to isolate the drying chamber, leaving all the auxiliary groups in the technical room: in this way powders handling for loading and unloading the product is confined in the clean room, thus eliminating any risk of contamination.

Italvacuum has two in-house CRIOX pilot systems for semi-industrial and laboratory drying tests on customer products. Pilot tests are used to analyze product samples and instantly alter process parameters to determine ideal drying cycle pattern.

According to trial results, the customer is offered the most appropriate technology to meet its specific requirements. At the same time Italvacuum collects important information for the correct sizing of the equipment.

If for organizational matters or because of the particular nature of the product involved, the customer wishes to carry out their own in-house tests, Italvacuum also offers skid-mounted systems that are readily transported and installed at customers site. In such cases, Italvacuum will also provide the technical personnel needed to conduct the trials.

The mobile device of the loading/unloading system can be fitted with the Clean Connex a system consisting of a C.I.P. washing nozzle with drain/ dryer unit which, after each operation and prior to back-off, cleans and dries all exposed surfaces. Tests performed on loading/unloading system with Clean Connex have shown residual contaminant concentrations to be well within the requirements of FDA standards (the "Guide to inspections validation of cleaning process" considers clean a system which exhibits contamination ratings <10 ppm). Using Clean Connex, residual concentration was recorded to be lower than 0.09 ppm. Clean Connex is a patented equipment.

For product loading a dryer-mounted batch drum loader is also available, consisting of a pneumatically-actuated moving device which connects the drum containing the batch to be processed to the CRIOX hopper.

The batch drum loader uses the double-cone rotation to bring the batch drum into the vertical position ready for subsequent loading. When in load position, the butterfly valve on dryer hopper is opened for pouring: the product is introduced by gravity.

Italvacuum has developed a special total-unloading device, to be installed inside the double-cone chamber above the drain valve. The Easy Unloading blades rotate clearing out from the CRIOX chamber the dried products which could be difficult to remove otherwise.

To facilitate inspection and SWAB testing, the latter being an FDA validation requirement for cleaning procedures, Italvacuum has designed and patented a large hatch for full access to CRIOX System, in order to perform all necessary operations easily and safely.

In addition to CRIOX, Italvacuum is the only manufacturer in the world that also produces in-house auxiliary units, vacuum system included, ensuring that they are sized correctly to meet any processing needs. Thus, the company offers:

CRIOX System is available from 55 to 12,000 liter capacity. Maximum loading depends on the type of product to be processed. Conversely minimum chamber loading capacity is unrestricted, since the action of the lump breaker units is effective even with a few liters of product.

Rotary dryers are widely used in food, feed, chemical, pharmaceutical, mining and other industries. The working process of the equipment is as follows: After the dewatered wet material is added to the dryer, the material is evenly dispersed in the dryer and fully contact with hot air under the rotation of the plate reader which is evenly distributed in the drum, accelerating the drying heat transfer and quality transfer. During the drying process, the material is discharged from the finished product in another section of the dryer by a star-shaped discharge valve, under the action of a slanting plate and hot air. This machine is suitable for drying all kinds of dregs with less than 85% water content, such as beer dregs, bean dregs, spray pulp corn husk, coal mud, fruit dregs, etc.

It has good effect for opening up feed resources, reducing feeding costs and environmental pollution for 10 years, the main export products of our drum dryer are vibration drying equipment, vacuum drying equipment, small and medium grain, food and agricultural, forestry and special products drying equipment, the annual export volume is more than a few hundred units, the main export areas are Southeast Asia and other developing countries, and has opened the door of the European and American markets.

The heat source for the rotary dryer comes from the combustion unit and uses a down-flow heating method. Therefore, the material that needs to be dried, from the feed box, feed slips into the cylinder, i.e., pushed back by the spiral plate. As the dryer is tilted, the material flows to the back end under the effect of gravity and rotation on the one hand, on the other hand, the material is repeatedly copied up, brought to the upper end and then continuously spread down, so that the material forms a uniform curtain in the tube, fully with the tube of the thermal airflow for heat exchange, due to the repeated spread of the material, the moisture contained in the drying, thus achieving the purpose of drying.

The operation opens the door and rotates the dewatered material evenly in the rotor, then closes and locks the door tightly. Depending on the type of material, select the appropriate time and adjust the timing device to the desired time. Press the start button to start the fan, and the direction of rotation of the rotor can be selected from unidirectional or bidirectional rotation according to the users needs. Simply rotate the computer board switch to one way or both ways and the machine will perform one way or both ways as required. (Forward 25 seconds, stop for 5 seconds, reverse 25 seconds) often watch the internal fabric turning from the observation window, if you find an unexpected situation should promptly cut off the power and check the fault. The machine will stop automatically when it reaches the specified time, and the operator must be asked to open the door to check the drying of the internal fabric.

The dryer is mainly used to dry materials of certain humidity or particle size in ore dressing, building materials, metallurgy, chemical and other departments. The dryer is widely used in tea, Chinese herbs, corn, vegetables, food, chicken manure, slag, towel quilt, sawdust, coal sludge, desulfurization gypsum, compound fertilizer, honeysuckle, straw briquetting fuel, charcoal machinery, wood chip pellet fuel, sawdust briquetting, agricultural engineering and other industries.

The main types of dryers are: rotary dryer, three-way dryer, three-tube dryer, intermittent dryer, direct heat dryer, clothes dump dryer, powder dryer, stone professional dryer, new dryer, second-hand dryer, industrial dryer, tea dryer, Chinese herb dryer, corn dryer, vegetable dehydration dryer, food dryer, chicken manure dryer, drum dryer, rotary dryer, stone dryer, rotary dryer, solder dryer, automatic dryer, oil dryer, electric heating dryer, energy-saving dryer, clothing dryer, towel quilt dryer, computer intelligent dryer, steam dryer, gas dryer, coal sludge dryer, slag dryer, sludge dryer, quartz sand dryer, sand dryer, fly ash dryer, desulfurization plaster dryer, sawdust dryer, tunnel dryer, dehydration dryer, compound fertilizer dryer, honeysuckle dryer, wine tank dryer.

The power generated by electric power, diesel power, wind power, flammable material power, etc. is heated by ambient air and transported to the perimeter of the pass-through, which then reaches the appropriate temperature for dehumidification treatment. The process is as follows: the wet material is fed to the hopper by a belt conveyor or bucket elevator, and then through the hoppers feeder into the feed end through the feed pipe. The slope of the feeding pipe should be greater than the natural inclination of the material so that the material flows smoothly into the dryer.

A dryer cylinder is a rotating cylinder that is slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the lower end, and contacts the material in a counterflow, there are also heat carriers and material together and flow into the cylinder. As the cylinder rotates the material runs by gravity to the lower end. In the process of moving forward in the cylinder, the wet material is directly or indirectly given heat by the heat carrier, so that the wet material can be dried, and then sent out at the discharge end through the belt machine or screw conveyor.

In the cylinder body wall is equipped with a copy plate, its role is to copy the material up and down, so that the material and airflow contact surface increases, in order to improve the drying rate and promote the material forward. Heat carriers are generally classified as hot air, flue gas, etc. After the heat carrier has passed through the dryer, a cyclone dust collector is usually required to trap the material in the gas. To further reduce the amount of dust in the exhaust gas, it should also be released after a bag filter or wet filter

The drying strength is high, and due to the high dispersion of the material in the airflow, the entire surface of the particles is actively the effective area for drying. Short drying time. The airflow dryer is simple in construction, has a small footprint and is easy to build and maintain. High handling capacity and high thermal efficiency. When drying non-bonded water, the thermal efficiency is up to 60%. The dryer achieves zero horizontal thrust, which greatly reduces the wear of the retaining wheel, and the barrel runs smoothly and reliably; the dryer adopts spherical pallet device, which makes the fit of the pallet and the roller always in linear contact, thus greatly reducing the wear and power loss.

rotary dryer machine design and working principle - sunco machinery

For evaporating the moisture from the wet raw material, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption. The rotary dryer machines has the direct heating type, in direct heating type. Direct heating type rotary dryer machine are used to apply heat / hot air to contact and heat the raw material such as sawdust, wood chips, chicken manure, silica sand, wood shavings, palm fibre, fly ash, etc. If it is not suitable to apply heat direct to heat and dry the raw material, then rotary dryers of indirect heating design can be furnished so that the heated hot gases will not come in direct contact with the wetraw material. Rotary Dryer is a simple, inexpensive unit forreducing the moisture content from the wet material. Several types ofrotary dryer machine design can be applied for drying different kinds of raw material. RotaryDryerMachine Working Principle: Wet material goes into the feeding hopper by belt conveyor or bucket elevator, then through the feeder goes into the feed pipe. The feed pipe slope is greater than the natural inclination of the materials, so that the material can inflow therotary dryersmoothly. There is one hot air furnace supply the hot flue gas for therotary dryerusually. The fuel can be waste wood, coal, natural gas, diesel, etc. Therotarydryercylinder is tilted slightly compared with horizontal. Materials and hot flue gas goes into therotary dryercilinder from the higher end. During the rotation of the cylinder, the material by gravity goes into the lower end. When the wet material is in the process of moving forward in therotarydryercylinder body, the lifting plates inside therotary dryercilinder makes the material up and down to contact with the hot flue gas completely. Thus, the moisture inside the wet material is evaporated into water vapour, and finally we get the dried materials. There is one high pressure induced draft fan is used to suck out the water vapour out of therotarydryerduring the drying process. Finally the water vapour with some dust goes into the cyclone dust collector. In the cyclone dust collector, the dust is seperated from the water vapour and falls down from the bottom of the cyclone dust collector; the water vapour leaves the cyclone dust collector from the top pipe of the cyclone dust collector, and finally goes into atmosphere through the chimney. At the end of therotary dryer, using one belt conveyor to transport the dried material into trucks or storage room directly. The rotarydryer seems very simple, but in fact it is one whole drying system, and the drying system should be designed according to: --- The features of raw material, for example the wet sand has surface water which is easier to be dried, but the wood chips has inner water which is more difficult to be dried. ---Initial moisture content(%) of the wet material. ---Output moisture content(%)the dried material needed. ---Bulk density (kg per cubic meter) of the wet material. ---Input capacity (ton per hour). ---Output capacity(ton per hour). ---Fuel Choice such as coal, waste wood, natural gas, diesel, etc. ---End use of the dried product. When the above information are clear, then Sunco Machinery engineers can calculate and design the suitable and reasonablerotary dryer systemfor the customers accordingly.

Direct heating type rotary dryer machine are used to apply heat / hot air to contact and heat the raw material such as sawdust, wood chips, chicken manure, silica sand, wood shavings, palm fibre, fly ash, etc.

If it is not suitable to apply heat direct to heat and dry the raw material, then rotary dryers of indirect heating design can be furnished so that the heated hot gases will not come in direct contact with the wetraw material.

Rotary Dryer is a simple, inexpensive unit forreducing the moisture content from the wet material. Several types ofrotary dryer machine design can be applied for drying different kinds of raw material.

Wet material goes into the feeding hopper by belt conveyor or bucket elevator, then through the feeder goes into the feed pipe. The feed pipe slope is greater than the natural inclination of the materials, so that the material can inflow therotary dryersmoothly.

Therotarydryercylinder is tilted slightly compared with horizontal. Materials and hot flue gas goes into therotary dryercilinder from the higher end. During the rotation of the cylinder, the material by gravity goes into the lower end. When the wet material is in the process of moving forward in therotarydryercylinder body, the lifting plates inside therotary dryercilinder makes the material up and down to contact with the hot flue gas completely. Thus, the moisture inside the wet material is evaporated into water vapour, and finally we get the dried materials.

There is one high pressure induced draft fan is used to suck out the water vapour out of therotarydryerduring the drying process. Finally the water vapour with some dust goes into the cyclone dust collector. In the cyclone dust collector, the dust is seperated from the water vapour and falls down from the bottom of the cyclone dust collector; the water vapour leaves the cyclone dust collector from the top pipe of the cyclone dust collector, and finally goes into atmosphere through the chimney.

rotary dryer design & working principle

For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption.Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design are used. If it is not possible to apply heat direct to the material to be dried, Rotary Dryers of the Indirect Heating Design can be furnished so that the heated gases will not come in direct contact with the material.

Rotary Dryer is a simple, inexpensive unit for reducing the moisture content of flotation concentrates, as well as chemical and industrial products. Frequently the saving of shipping weight so effected will pay for the dryer in a few months. Difficulties from freezing while in transit are also eliminated. Many industrial projects are now using Dryers for control and production purposes on many materials.

Three main types of Rotary Dryers can be supplied. The direct heat unit is used when it is permissible for the drying gases to come in direct contact with the material being dried. Partition plates increase the heating surface. Drying may be by hot air or exhaust gases from other operations. If this drying gas has a deleterious effect on the product, then an indirect type of dryer can be supplied. A further derivation is the Tedrow Steam Dryer.

Of the different types of dryers that there are the most common is the ROTARY DRUM DRYER/Kiln, This type of drier is common not only in the mining industry but you will find them in fertilizer plants, Cement plants, and peat hogs to name but a few.

The theories behind these machines are very simple, heat an air space up, and then tumble the material to be dried through this space until it is dried. All though it sounds simple there are problems that have to be solved before the required results are met. But first, so you know what we are talking about lets go through the design of a drier.

First is the KILN, this provides the heat, The BURNER is inside this portion. The fuel for the burner is usually diesel although heavy crude oil could be used in some cases. To be able to generate enough heat to dry the concentrate air must be added by way of a BLOWER. In front of the kiln is the point that the wet concentrate enters the drier. It is put into the revolving SHELL. The shell is on a slight incline. As the Concentrate is tumbled through the hot air mass of the drier it travels down this incline to the exit of the drier.

At this exit point the concentrate is either deposited straight into a storage area or taken to the storage area by a conveyor. It is also at this point that there is an EXHAUST HOOD. This provides a controlled escape passage for the fumes and water vapor that is generated by the concentrate drying. This is a very important function and the operator will have to be sure that it is open at all times. If it should become blocked the water vapor will not be able to escape. The concentrate will become wet and sticky which will result in the discharge plugging. The wet sticky concentrate will also lower efficiency level of the drier for an extended period of time. This happens because inside the drier shell are what are termed FLIGHTS these are flat pieces of metal that are bolted onto the shell.

They are there to lift the concentrate up to the top of the shells rotation and drop the concentrate through the hot air. If the water vapor isnt taken away, the concentrate becomes sticky from reabsorbing the water. This sticky concentrate will fill the spaces between the flights.

The concentrate will not be lifted and dropped through the hot air. This results in a long term condition of poor performance even after the initial problem has been cured. These flights will remain buried in concentrate. This removal of the water vapor is one of the functions of the blower. It assists the natural process of air movement as the hot air mass expands. To prevent the buildup of concentrate on the flights there are often CHAINS attached to them. As the drier revolves the chains slap the flights preventing concentrate from building up on dryers walls.

The drier shell is rotated separately from the stationary kiln section. To achieve the rotation a BULL GEAR is attached around the shell section. There are also two flat rings attached to the shell. These provide surfaces for support rollers to roll on. There is another problem that the inclined shell has, the incline causes the shell to want to slide in the direction of the incline. To prevent this additional rollers are attached to the last set of rollers.
