Hongji Group Product Superiority. Spiral classifiers or screw classifiers are important ore dressing equipment. Spiral classifier is mainly used in metal beneficiation production line to classify minerals according to their different sedimentation velocity. Screw classifiers can be divided into high weir type low weir type and sank type according to the height of the weir.

The design of these classifiers (rake spiral screw) have inherent problems First they are very susceptible to wear caused by the scrubbing action of the ore that plus all of the mechanical moving parts create many worn areas to contend with. The other problem that these classifiers have is that they are easily over loaded.

Rake classifiers are also used for close circuit grinding. Both rake and spiral classifiers are more efficient in classifying the coarse particles. But they are very costly for installation. In these classifiers the separation achieved is distinct. Dry classifiers. Dry classifiers are based on the principle that separation by air fluidization.
