Sorting size 0.3-0.02mm thin materials of iron ore,ilmenite,chromite,pyrite,zircon,rutile,monazite,P B ore,etc. Spiral chute application: This machine is applicable for selecting materials with size 0.3--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 rare matels and nonmetal minerals. The concentrating process is stable and easy to control with this spiral chut, allowing feeding thickness change to a large extent.
Stick up the spiral chute, adjust vertical line, and fix it to a proper place with hob ore timber; deliver the ore slurry to the two feeding opening at top of the spiral chute with the help of sand pump; add supplementary water to adjust slurry thickness. Then slurry flows down automatically and rotarily from the top. A inertial centrifugal force is formed along the rotary bevel with flow speed, so that ore and sand can be divided under rotary steam and centrifugal force according to the slurry's different specific gravity, grain size and shape. Next, final ore flows to the final ore hopper and coveyed out by pipe and picked up, and final sand flows to final sand hopper and coveyed out by pipe to sand pond. Then remove the sand pump. That is the whole concentrating process
