Classifying Machines – Spiral Classifier

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

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.
