Product Description

Plastic extrusion machine screen change system-continuous screen changer
GM-DP-R series

This kind of polymer melt filter used on plastic extrusion machine  now is widely used on the plastic recycling machine. 
 Now in the market , most of the  recycling machine is the under water strands pelletizing, So if the we use the tradtional plate type screen changer, the strands will be interrupted when the screen change is required, and we need to draw the strands again, it is waste of time , and labor ,and this GM-DP-R series continuous screen changer solve this problem perfectly. the melt flow is always full fill in the channel of the screen changer, so the strands will not be interrupted.

This GM-DP-R series  continuous screen changer/ melt filter is consist of
The main body of the screen changer
 Hydraulic unit 
Electrical controlling pack
 
Features of this kind of GM-DP-R series of continuous screen changer for plastic extrusion machine
1)Two round  removable breaker plates on each bearing piston
2)"Continuous type" means operation of screen change without machine halt or disruption of melt flow.
3)Equipped with three steps of gas venting system
4)Fit for almost all kinds of polymers
5)Flexible installation ways
6)It works well under the high pressure 400bar(40Mpa) not impact the high performance.
7)The filtration screen area covers from 56cm² to 520cm², depending on the size, fit for output range from 30kg/h to 1800kg/h.
