The principle of the equipment

The screening machine utilizes the size and quality differences of materials, as well as the varying settling velocities of liquids. Small materials settle to the bottom of the tank while larger materials settle. A grading screen is a device that uses a spiral to push materials upwards and then mechanically screen them. It can filter the materials in the mill according to their grades, and then screw larger materials into the feed inlet of the mill using spiral blades to overflow the filtered small materials from the overflow pipe. The base of the grading screen is made of channel steel, and the body is welded from steel plates.
