Spiral Chute
Spiral chute is applicable to material separation of size 0.3 - 0.02 mm, such as of Iron ore, Ilmenite,
Chromite, Pyrite, Zircon and Rutile, Monazite, Tungsten ore, Tin, Tantalum ore, Niobium mine and
other non-ferrous metals, precious metals and non-metallic minerals, which with proportion differences.
Spiral chute is gravity concentrators and separate minerals of different specific gravity according to their
relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
Spiral chute is made up of feeder, feed chute, spiral flute, bracket, intercepting slot, and supporting frame, etc.
Spiral chute feature
1.Reasonable structure and small occupation area
2.High recovery, high efficiency, and precise separation,
3.Light in weight, rust and corrosion resistant;
4.Simple installation and Minimal maintenance requirements
5.Low operating cost and long operating life
6.Reliable running with minimal operator attention.
Spiral chute working principle:
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
