Washing & Classifying. Sand, aggregate and minerals must be washed in order to meet many required specifications for various projects. Washing and classifying equipment provides producers with the ability to remove excess water and deleterious materials such as clay, silt, shale, coal, soft stone, roots, twigs and other debris from the rock.

Dewatering Screw Classifiers once had a wide vogue and still are used in some pulp circuits. They were more or less troublesome because solids tended to accumulate on the sloping sides, sloughed off periodically, and plugged the discharge in the apex; the sand discharged was too dilute and contained too much slime; and sand was frequently carried over with the slime.

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 the required 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.

The grit classifier is effective over a wide range of grit particle sizes, including sugar sand. When the grit slurry is transferred to the grit classifier, the inlet flow is directed diagonally downward. As grit settles, a shaftless screw carries the grit from the bottom of the hopper to the discharge, further washing and dewatering it.
