Spiral Chute

Our spiral chute is applicable for selecting materials with size ranging from 0.3 to 0.02mm, such as iron ore, ilmenite, chromite, pyrite, azorite, rutile, monazite, phosphorite, oxide ore, tin ore, tantalum ore, niobium ore and other nonferrous metals with distinct specific gravity difference, and for rare metals and nonmetal minerals.

Features
Glass fiber reinforced plastics spiral rotary chute is the national new type equipment developed in 1977 combining with features of spiral ore washer, spiral chute, shaking table and centrifugal ore separator. Our spiral chute is the ideal equipment for mining or selection mine, especially in seashore, riverside, sand beach or creek. Our spiral chute has reasonable structure, simple installation, small occupation, easy operation, stable and clear selection, large capacity, high efficiency, high enrichment selection ratio and recovery, stable running etc. Besides, it has the advantages of light weight, dampproof, and antirust, and corrosion resistance, high adaptability of feeding ores in different thickness, size and grade.

Working Principle of Our Spiral Chute
First, stick up the spiral chute, adjust vertical line, and fix it to a proper place with hob or timber. Then, deliver the ore slurry to the two feeding opening at top of the spiral chute with the help of sand pump and add supplementary water to adjust slurry thickness. After that, slurry spirally flows down automatically, during which an inertial centrifugal force is formed. Under the action of rotary stream and centrifugal force, the ore and sand can be separated according to the slurry's different specific gravity, grain size and shape. Next, ore concentration flows to the final ore hopper and is discharged via a pipe, and final sand flows to final sand hopper and then is conveyed to sand pond by a pipe and removed by a sand pump.
