J+A Screw Classifier
The J+A screw classifier systems are free-standing units used for the separation of mineral grit from other types of solids. The screw classifier hopper maintains a water level through a series of weirs. A peripheral weir removes floating solids and a second weir positioned within the trough wall removes other solids that are lighter than grit. A hydrocyclone can be used to receive the flow and reduce the liquid delivered to the classifier, retaining the mineral particles.
