Product Description

Spiral Chute is suitable for sorting gold mine, silver mine, alluvial gold mine, lead-zinc mine, copper mine, tin mine, titanium iron mine, pyrite mine, hematite, limonite, chromite, ferberite, tungsten, tantalum-niobium, colliery, monazite, sapphire , barites, rutile, zircon, etc. Spiral Chute is high efficient equipment for sorting ferrous, nonferrous, nonmetallic mine and minor metal mine.

Features of spiral chute
1. Stable, easy control, wide range of concentration
2. Large capacity, high enrichment ratio, high recovery rate
3. Small cover space, less water consumption, simple structure, no need of power
4. Simple installation, convenient operation, less investment, quick return

Working principle of spiral chute
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 as concentrate, middling and tailings.
