The spiral chute is a gravity separation device that uses the inertial centrifugal force generated by the pulp during the spiral rotary motion to separate light and heavy minerals.
Applied material: It is mainly used for sorting fine-grained iron ore, ilmenite, chromite, pyrite, zircon, rutile, monazite, phosphorite, tungsten ore, tin ore, tantalum ore etc.
Processing ability:0.2-8 t/h

Ore pulps are uniformly fed into machine and form different layers as they pass across chute. Heavy minerals precipitate to bottom and are moved toward inner edge by the comprehensive action of various forces; light minerals are moved toward outer inner due to the speedy rotation. As a result, mineral particles with different density are divided into three zones-concentrate, middling and tailing.
