- Product Introduction
- A gravity separation equipment of separation different weight mineral by inertial centrifugal force pulp produced in helix turning motion
- Product improvement
- There are 3 kinds of chute for user to choose, glass steel chute, Xinhai wear-resistant rubber liner, polyurethane rubber liner.
Stable, easy control, wide range of concentration
Large capacity, enrichment ratio, high recovery rate
Small cover space, less water consumption, simple structure, no need of power
Simple installation, convenient operation,less investment, quick return
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.
Spiral chute is suitable for treatment of 0.6-0.03mm lode and placer, but high mud content is bad for separation. At present, spiral chute has been widely used in the treatment of iron ore, tungsten, tin ore, niobium tantalum ore, coastal and riverside placer and gold ore.
