Double piston screen changer with enlarge filter screen and continuous operation 
This GM-DP-L series Double piston screen changer with enlarge filter screen and continuous operation     is consist of
 
The main body of the screen changer
 Hydraulic unit 
Electrical controlling pack(this part is optional choice by customers, the above picture shows two kind of controll system)

This GM-DP-L series d Double piston screen changer with enlarge filter screen and continuous operation  is designed based on GM-DP-R series dual rods continuous screen changer ,  this kind of Double piston large capacity continuous screen changer  enlarge the filtration area by instead  the round breaker plates as the rods full of holes, and the filter screen is wrapped on the rods. And this kind of continuous screen changer now is widely used for the hot melt adhesive, high output plastic recycling machine.


So the GM-DP-L continuous screen changer filter area is much more larger than the GM-DP-R series continuous screen changer, it meets the high yield device requirements.
 
After successful trials at Kunshan ,A ABS recycling factory, we have equiped two sets of the ABS recycling machine with this kind of double piston continuous screen changer with large capacity.Through the filtration process, The ABS flakes can be processed at a throughput rate of 1100kg/h. That is to say, this kind of large capacity screen changer can meet the high output recycling extrusion machine .
 
Characteristics of  GM-DP-L series     Double piston screen changer with enlarge filter screen and continuous operation 
The filter screen is wrapped on each slide bearing bars  full of small holes-the same function as the breaker plates
"Continuous type" means operation of screen change without machine halt or disruption of melt flow.
Equiped with air venting system
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 400cm² to 2500cm², depending on the size, fit for output range from 100kg/h to 4800kg/h.
