This series of screen changer consists of main body, slide plate, heater and hydraulic unit with accumulator. It is driven by hydraulic power, and the slide plate carries 2 pieces breaker plates can move linearly in both directions to achieve screen changing in a short time. Anji patented technology on the sealing system design. Automatic compensation on sealing gap can be realized during screen changing process. Compatible with extruders for various polymers processing for most polymer at high output. With highly precise design, the screen has good abrasive resistant, high pressure performance, ensuring large effective filtration area and improving filtration effect. It works well even under high temperature up to 300 and high pressure up to 50 MPa. Screen changing time ≤ 2 seconds with pressure accumulator. It can be used for sheet, plate, pipe, film, blown film, wire, cable, profile, granulation (masterbatch, compounding, blend features granulation, cable materials, functional masterbatch, synthetic granulation, recycling and pelletizing) and it is suitable for most of thermoplastic plastics.
