Product introduction

Spiral chutes are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. It has extremely good performance and effects in processing placer of beach, riverside, seashore and stream.

Spiral chutes are made of polyurethane lined fiberglass with wear-resistant corundum inner surface.

Spiral Chute — 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.

Features

Spiral Chute features:

1. It is the newly re-selecting equipment for gravity way mineral processing.

2. It is a high efficiency gravity concentrator of the international advanced standard.

3. It is widely used to separate the hematite, stannum, tungsten, tantalum, niobium, gold ore, colliery,monazite, rutile and zircon of the size between 0.3 and 0.02mm , and the other metals and nonmetal minerals of enough proportion deviation.
