Spiral chute, which is also known as spiral chute separator, is a kind of gravity separation equipment.
Spiral gravity separator spiral chute is also called spiral concentrator or gravity separator, it’s a kind of gravity concentrator which can separate mineral particles according to density, granularity and shape by the interaction of centrifugal force, friction force of chute surface, water flow pressure and gravity of minerals. Spirals are made of high-density fiberglass, high quality emery and unsaturated resin.
The spiral chute is suitable for separation of 0.3-0.02mm fine materials such as iron ore, ilmenite ore, chromite ore, pyrite ore, zircon ore, rutile ore, monazite ore, tungsten ore, tin ore, tantalum ore, niobium ore and other materials with enough specific gravity difference. It is the best roughing gravity equipment, which has been widely used in ferrous and nonferrous metal mines.
The spiral chute parts have a distributor and feed chute in the upper part and a product interceptor and collection chute in the lower part. The entire equipment is framed vertically with steel frames.The spiral chute is similar to the thread shape. The movement of the materials inside can be divided into three stages: the material introduction stage, the material acceleration stage, and the material uniform velocity warehouse stage. The third stage lasts the longest and is the key to materials crushing.

A Spiral Chute is a gravity-fed separator that uses a helical pathway to separate minerals based on density and particle size.
A Spiral Chute uses a combination of gravity, centrifugal force, and frictional drag to stratify and separate valuable heavy minerals from lighter waste materials.
Spiral Chutes are commonly used for separating coal, iron ore, rutile, zircon, ilmenite, and other heavy minerals from sand and gravel.
Spiral Chutes offer low operating costs, high capacity, simple operation, and no moving parts, making them a cost-effective separation solution.
Consider feed rate, particle size distribution, mineral density, chute material, and number of turns when choosing a Spiral Chute.
