General description

It is mainly used in pre-classification and examination classification of grinding loop in concentration plant and aggregate plant as well as desliming, dehydration in sand washing process and so on .  It can be classified into single and double spiral types by to the spiral quantity; and into high weir and sinking types by different depth of spinning blade dipping into overfall surface. The former can be used in classification of ore with overflow granularity 0.83-0.15mm, and the latter in classification of ore with overflow granularity 0.15-0.07mm.
