spiral chute

Ore-distributor is placed freely on the cross (tripod) of the support table, uniform slurry is fed slowly to the spiral groove surface through the bunker mounted to the first end of spiral groove for sorting. The end of the spiral groove has valve product-interception trough which separate products along radial direction by grade into three (or four kinds). By adjusting the position of the valve, can change the interception width of each kind. Product gathering unit is a concentric annular cylindrical bucket that gathers and respectively exports multipoint ore flows which have been pooled. Spiral chute cross slope, the curve changes, especially suitable for fine particulate material sorting. This processing equipment has advantages as simple structure, no moving parts, light weight, no noise, configured installation and easy maintenance.

FRP spiral chute is formed by six parts, ore-distributor, bunker, helical groove, product interception trough, product gathering bucket, tank bracket (including crosses or tripod) and etc. The helical groove which is connected by the spiral sheet is the main part. Spiral sheet is made of glass steel (glass fiber reinforced plastics), bolted together, sorting face of spiral groove has a layer of preformed surface which is wearing layer. The processing equipment is featured by light, strong and durable. The top has a multi-tube ore-distributor, can uniformly distribute ore, easy to control.

Spiral concentrators are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particles hydrodynamic properties (e.g. drag). The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid particles that have come out of suspension.

As larger and heavier particles sink to the bottom of the sluice faster and experience more drag from the bottom, they travel slower, and so move towards the center of the spiral. Conversely, light particles stay towards the outside of the spiral, with the water, and quickly reach the bottom. At the bottom, a cut is made with a set of adjustable bars, channels, or slots, separating the low and high density parts. Many things can be done to improve the separation efficiency, including: -changing the rate of material feed -changing the grain size of the material -changing the slurry mass percentage -adjusting the cutter bar positions -running the output of one spiral separator (often, a third, intermediate, cut) through a second. -adding wash water inlets along the length of the spiral, to aid in separating light minerals -adding multiple outlets along the length, to improve the ability of the spiral to remove heavy contaminants -adding ridges on the sluice at an angle to the direction of flow.

Typical spiral concentrators will use a slurry from about 20%-40% solids by weight, with a particle size somewhere between 1.5-.075 mm (17-340 mesh), though somewhat larger particle sizes are sometimes used. For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm3; and because the separation is dependent upon size and density, spiral separators are most effective at purifying ore if its particles are of uniform size and shape. A spiral separator may process a couple tons per hour of ore, per flight, and multiple flights may be stacked in the same space as one, to improve capacity.

Hi speed disc stack separators are used for separating fluids with different densities or used to separate particles from liquids. Due to the centrifugal force in separators, the fluid/particles with the greatest density collect in the outer periphery of the separator bowl. Both fluid phases are then discharged through separate outlets with any solids discharged at the bottom.

Decanter centrifuges are used to separate solids from liquid. These decanter centrifuges use a bowl and rotating scroll to separate the solids. The solids are dewatered as they continue up an inclined beach and exit out the decanter through a chute. The liquid exits the decanter through weirs at the opposite end from the solids chute.

The emmie comprises a trolley-mounted centrifugal separator and electrical oil heater for use on ships. Moved between marine hydraulic systems, it removes water and 99% of all particles from oil, increasing oil service life and system reliability.

Alfa Lavals unparalleled decanter centrifuge technology has paved the way for a series of ground-breaking innovations, all based on proven technology renowned for reliability. Together, these ensure a unique combination of better performance and lower energy consumption, resulting in lower operating costs than ever before.

The ALDEC G3 is built around the Slimline design a breakthrough in decanter centrifuge performance and capabilities. The smaller conveyor diameter makes room for more liquid in the pond, and allows higher bowl wall pressures, resulting in either drier cake or using less polymer. Patented Alfa Laval Power Plates also effectively reduce the power consumption of ALDEC G3 decanter centrifuges, making a big contribution to cost savings.

The ALDEC G3 decanter centrifuge design provides significantly improved separation results and better control of all the variables using up to 40% less energy. Lower power consumption saves money as well as improving the environmental profile of any dewatering or thickening operation.

The Spiral separator/ spiral chute is the earliest mining machine. It has been used to classify the granularity 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals. The non-metallic minerals which have a big enough specific gravity difference. Spiral chute principleRaise the spiral chute and fix it in the proper position, sand pump send the ore to the feed inlet, adding water to adjust the concentration of the slurry. The slurry naturally swirls from high to low and generates an inertial centrifugal force in the rotating bevel flow rate. The mineral is separated from the sand by the gravity and centrifugal force of the swirl by the difference in specific gravity, grain size and shape of the ore. The concentrate flows into the concentrate bucket and is connected by the pipeline. The tail sand flows into the tailing sand bucket and is connected to the sand pool by the pipeline, and then drained by the sand pump to complete the whole process of the beneficiation.
