China Continuous Screen Changer for PP PE Pipe Extrusion Machine

Benifits of the melt filtration system for plastic extrusion machine
1, leak free mold
2, simple operation and uncomplicated screen change
3, high operational reliability
4, Easier access and less interference for the operator
5, no need to stop the working machine when chnage the screen
6, improve the quality and increase the output of the final products

Indroduction of the "continuous screen changer"
Continuous piston-type screen changers come in single- or multiple-piston styles and typically employ more than one breaker plate in the flow so that each breaker plate can be removed, one at a time, for screen changing without interrupting the flow. Piston units also include a venting/de-aeration process to ensure that no entrained air enters the flow and creates off-spec product. And about the piston type continuous screen changer, we may have two kinds of this screen changer: single pistion type continuous screen changer and double piston type continuous screen changer. and there are three kinds of different double piston screen changer
1, with round breaker plate
2,with elongated breaker plate
3,with the screen wrapped on the pistons

Here we main introduce the most common type GM-DP-R series double piston continuous screen changer with round breaker plates.

Characteristics of GM-DP-R series Continuous piston-type screen changers - double piston continuous screen changer with round breaker plates.
Two round removable breaker plates on each bearing piston
"Continuous type" means operation of screen change without machine halt or disruption of melt flow.
Fit for almost all kinds of polymers
It works well under the high pressure 400bar(40Mpa) not impact the high performance.
The filtration screen area covers from 56cm² to 520cm², depending on the size, fit for output range from 30kg/h to 1800kg/h.
