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 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.

Stainless Steel Shaftless Classifier KWS Manufacturing

Biogas can then be processed to produce renewable clean energy. The slurry is fed into the inlet hopper of the classifier in a batch operation. The struvite settles to the bottom of the classifier hopper and is conveyed out by the shaftless screw conveyor. Once the water drains out it gets sent to Environmental facilities for further processing.

Screw Wikipedia

Explanation. A screw is a combination of simple machines—it is, in essence, an inclined plane wrapped around a central shaft, but the inclined plane (thread) also comes to a sharp edge around the outside, which acts a wedge as it pushes into the fastened material, and the shaft and helix also form a wedge in the form of the point. Some screw threads are designed to mate with a complementary
