This DHB 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.
Features of DHB series of screen changer
Deao 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 at high output.
Filtration screen diameter ranges from 70-360mm.
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.
