Work Principle

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.

Product Application

Spiral chute (glass fiber reinforced plastics spiral chute) is applicable to metal and non-metal ores with adequate density difference, like iron, chromite, pyrite, tin ore, tungsten, tantalum, niobium, gold ore, colliery, monazite, rutile and Zirconium.
