Spiral Chute
A spiral chute, also called mineral spiral separator, is a kind of gravity separation equipment. It makes use of the inertial centrifugal force generated by the ore pulp in the spiral rotation motion to separate light and heavy minerals.A spiral chute combines the features of a spiral concentrator, vibrating table, and centrifugal concentrator. It is the best equipment for mining and beneficiation, especially for placer mining on seashores, riversides, sand beaches, and streams.
Capacity
120-640t/h
Feeding size
0.3-0.02mm
Application
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
Spiral chute application
The spiral chute can be used to separate fine-grained minerals with a difference in specific gravity and a particle size of 0.3–0.02 mm. Applicable materials are gold placer, iron ore, magnetite, ilmenite, chromite, pyrite, zircon, rutile, monazite, tungsten ore, tin ore, tantalum ore, niobium ore, antimony ore, and other non-ferrous metals, rare metals, non-metallic minerals.
The structure of the spiral chute
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.
The main part of the spiral chute device is the spiral flight which is made of glass fiber-reinforced plastic. The inner surface of the spiral groove is coated with a wear-resistant lining, usually a polyurethane wear-resistant glue or an epoxy resin mixed with artificial gold steel sand.
