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.
