Spiral Chute for Mineral Concentration
Description
Spiral chute is widely applied to mineral separating of size 0.3 – 0.02 mm, such as ilmenite,
chromite, pyrite, zircon, rutile, monazite, phosphate, tungsten ore, tin, tantalum, niobium ore
and other non-ferrous metals, precious metals and non-metallic minerals.
Spiral Chute Working Principle
Spiral chute is working under the force of water flow, gravity, inertial centrifuge and friction.
Slurry is pumped to the top of the spiral, and it enters a feed distributor that evenly
distributes the feed to each spiral concentrator. The design and shape of the spiral make it work,
when combined with gravitational acceleration. As the slurry travels the spiraling path down the
spiral, mineral grains settle and start sorting according to size, density and to a lesser extend
shape. Low density particles are carried with the bulk of the water towards the outside of the
spiral, while particles with the greatest density migrate towards the inside of the spiral.

Main Features
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;
7. Strong adaptability to fluctuation of feeding amount, density, size and grade.
