Gravity separation machine spiral chute classifier for tin ore
Introduction
Spiral chute is high efficient gravity equipment for mineral processing. It doesn’t need the power but utilize the different particles by the effect of gravity, water pressure and friction to achieve the separation of the useful minerals and gangue. It is made of the fiberglass with wear-resistant polyurethane and corundum cover.
Working principleSpiral chute is working under the force of water flow, gravity, inertial centrifuge and friction. 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 concentrate, middling and tailing.
Applications:
Spiral chute is suitable for processing iron, tin, tungsten, tantalum, chrome, niobium, gold, coal, monazite, rutile, zircon and
other metal, nonmetal minerals with enough specific gravity dispersion of granularity ranged from 0.02 to 0.3mm lode and placer, but high mud content is bad for separation.
