At present, consummated product series including more than 20 product specification have taking shape, which almost supply demand of market.

Product Introduction
The spiral classifier is the preparation equipment, which is used for pre-classification, check classification, ore washing, desliming and other work in grinding circuit. It has many features such as simple structure, reliable running, convenient operation and the easy forming of closed circuit with diameter less than 3.6m.

Product Principle
The spiral classifier is in accordance to the principle that different proportion of solid particles have different sedimentation velocity.

Product Classification and Application
There are single and double spiral classifiers according to the amount of spiral shaft.
On the basis of the weir height, the spiral classifier is divided into high weir, low weir and sinking types. The high weir type is usually used for coarse particle classification, with standard of overflow particle size limit being greater than 0.15mm. The low weir is not used to classify materials, and it is mainly as a tool of desliming through washing ore sand. The sinking type is usually used for fine particles classification, with standard of overflow particle size limit being less than 0.15mm.
