hydraulic extrusion double screen changer for plastic recycling

The granulator screen changer is mainly used in granulation, PE, PP, PPR, PERT pipes, plates, sheets, cast films, non-woven fabrics, chemical fiber spinning, and other production processes that require uninterrupted material flow and high continuity during screen changing.

The plastic granulator screen changer is a dual column and dual station screen changer. During operation, two filter screens work simultaneously. When a screen changer is needed, the hydraulic station can be activated to perform the screen changer action. When replacing the filter screen, one screen works and the other screen is replaced. The two screens are alternately replaced. Through the feeding and exhaust devices, the air in the flow channel is completely discharged to achieve the production requirements of non-stop screen changer, no material leakage, uninterrupted material flow, small material pressure fluctuation, small impact on production, and good continuity.
