Spiral Classifier is a traditional type of classification equipment, mainly for metal mineral processing for the slurry density and particle size on the wet grade, mining operations could also be used in the flow desliming.
it is hard to get very fine product, especially for product with -200 mesh over 90%; It is not easy to automate control it, and the classification efficiency is not high; It needs a large space for installation.

spiral classifier - mineral processing
Spiral classifier and hydrocyclone are the main equipments for the classification operation of the concentrator. Although the rapid development of the cyclone once made the spiral classifier lose its market, but with the continuous changes in the requirements of the selection plant, it was found that the spiral classifier also has its advantages.
The spiral centrifugal classifier has the advantages of strong continuous operation, large processing capacity, low energy consumption per unit output, and convenient maintenance. It can handle particles with a diameter of 1um-10mm.
The horizontal spiral centrifugal classifier adopts the method of wet classification, and its processing capacity can reach 1~20 (m3 slurry) kg/h. It is widely used in minerals, metal powders, chemical raw materials, pigments, fillers, etc.
The screw classifier is based on the principle that the solid particles are different in size and specific gravity, so the settling speed in the liquid is different. Fine ore particles float in the water and overflow, and coarse ore particles sink to the bottom of the tank.
Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
There are four classifiers: high weir single spiral and double spiral, submerged single spiral and double spiral.
The spiral classifier is widely used in the classification of the grinding circuit of the concentrator and the operations of washing, desilting and dewatering. Its main advantages are simple equipment structure, reliable work and convenient operation.
1. It is used for the separation of machine-made sandstone powder, which can control the content of machine-made sandstone powder very conveniently and meet the requirements of users.2. It is suitable for dry technology large and medium-sized sand production lines.3. The content of 0.000.75mm stone powder can be adjusted between 2%-15%.4. Stone powder quality is easy to control, fineness adjustment is convenient, flexible and reliable.5. Using frequency conversion control technology, the operation is more concise.6. It can be connected with the mill in the closed circuit of the grinding circuit. Compared with hydrocyclone, the power consumption is lower.7. The main disadvantage is that the classification efficiency is low, the equipment is bulky, and the floor space is large. Due to the limitations of equipment specifications and production capacity, it cannot generally form a closed circuit with a ball mill of 3.6m or more.
The spiral classifier is divided into two types: high weir type and submerged type. High weir classifier is suitable for coarse particle classification, the maximum size of overflow is generally 0.4~0.15mm; submerged classifier is suitable for fine particle classification, the maximum size of overflow is generally below 0.2mm.
small and portable gold wash plant - jxsc machine
JXSCSmall andPortable gold wash plant with trommel, fullyCustomizable & moveable. Equip with the sluice box, gold centrifugal concentrator, shaker table, gold trommel, sand washing machine, vibrating feeders, vibrating screen, pumps, and the like portable mining equipment according to different conditions. CapacityCustomizable 1-300TPH Applicationdry land, beachside, stream, river gold mining, etc. Servicemining process flow design, quick machine selection and quotation, on-site installation, one year warranty.
DescriptionThe portable gold wash plant integrates ore mining and gold mineral processing operation, includes the excavation system, mineral processing equipment, water supply system, tailings treatment system, power supply, etc. TypeThe configuration of the mobile gold wash plant varies with the ore nature, processing capacity, site environment, and other factors. hard rock gold deposit, alluvial gold (placer gold) deposit; dryland placer gold, river gold (need gold dredger), river bed & beachside gold; contains sticky clay, sludge, gold trommel wash plant equipped with trommel scrubber, sand washing machine; Using bulldozer and excavator stockpiles the gold-bearing gravels near the gold mining wash plant, feeds gravels into the wash plant from feeding hopper (mount a vibrating screen to primary classify the gold-bearing gravels), the oversize material slides out, and the undersize material is mixed with water flow through the gold concentrator machines like gold centrifugal concentrator, portable shaker table, portable sluice box, tailings are discharged routinely. Portable gold wash plant manufacturerJXSC has been supplying gold mining equipment for large scale mining and small scale mining plant since 1985, develop deep cooperation relationships with gold mine companies in South Africa, Australia, Ghana, Russia, Congo, etc. Contact us to get the best gold wash plant price.
Portable gold mining equipment and process flow 1. Feeding: dredge pump, hopper feeder with vibrating grizzly bar. 2. Washing and screening: usually use rotary scrubber, gold trommel, sand washing machine, vibrating screen, etc. 3. Beneficiation: gold centrifugal concentrator, shaker table, sluice box, mineral jig. 4. Water supply 5. Tailings 6. Mobile System: Composed of chassis and traction steering two major components, 4 axes 16 tires, 4 mechanical legs support centrifuge, can be turned in situ 180 degrees, easy to move to the workplace. Working principle1. Dry gold mining Dry land mobile gold wash plant with rubble tyre, easy to move on, can separate placer gold from ancient river, dry beach sand. Dryland gold mining usually use trommel screen combines the small gold jig and gold sluice box into a single mobile gold recovery plant to process placer gold, monomer lode gold. This type of small scale gold wash plants has a light weight, easy to maintain, low cost. 2. River gold mining The river gold panning equipment, mostly as the gold dredging ship floating on the water, it is a multifunctional placer mining equipment that combines excavation, ore washing, beneficiation, tailings disposal, and power supply, water supply. River gold dredger can work at stream, river, offshore, beach side, etc. But as for small gold wash plant, the cost of the gold dredger may be a huge part. How to build a small gold wash plant? Using dredge pump pumping the river bed fine sand to the near land portable gold trommel, wash and classify the undersize material to gold centrifugal concentrator and shaker table.
