1. Descriptions of spiral chute :
gravity spiral chute is our company's concentrating experienced scientific product, The product is made of the fiberglass lined with wear-resistant polyurethane and corundum cover; the advantages are light, moisture proof, anti-rust, wear proof, anti corrosion and no noise, properly suitable for granularity 0.3-0.02 millimeters fine grain
2.Application of spiral chute :
A. which is the best separating equipment, especially for separating sand ore in beach, riverside, seashore and stream.
B. metal mines such as iron, tin, tungsten, tantalum-niobium, gold ore, monazite, rutile, zircon and other metals.
C. non-metallic minerals coal mine, coal of coal chemical industry, the sulfur-selection factory
D. scientific research, the design department, the colleges and universities lab.
3. Use and working principle:
Make the screw chute stand, adjust the vertical line, fixed the proper place with the iron structure or wood, make the ore sand deliver to two feed openings of the screw chute top, enter enough water, adjust the mash chrome, the mash flows freely from the high, produce the intertial force at the speed of the rotary, divided the sand and ore, the concentrate comes into bucket with the tract, gangue comes into the bucket with the tract to the sand pool, and pump off, complete the whole process.
