Product Description
Full automatic large filtration area continuous screen changer
This GM-DP-L series Double piston large filter area continuous screen changer for plastic extrusion machine 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 Large filter area continuous screen changer for plastic extrusion machine is designed based on GM-DP-R series dual rods continuous screen changer , this kind of 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 full of holes. And this kind of continuous screen changer now is widely used for the hot melt adhesive, high output plastic recycling machine.
So the filtration area of the GM-DP-L series screen changer is much more larger than the GM-DP-R series continuous screen changer, it meets the high yield device requirements.
After successful trials atJiangsu Province,an ABS recycling factory, we have installed two sets of this GM-DP-L series large filtration area continuous screen changer on the ABS recycling machine .Through the filtration process, The ABS flakes can be processed at a throughput rate of 1100kg/h. And during the screen change process, the strands do not interrupted . and there are no bubbles in the final granules That is to say, this kind of large capacity screen changer can meet the high output recycling extrusion machine and can realize the continuous production without interruption
Characteristics of GM-DP-L series large filtration area continuous screenc hanger for plastic extrusion machine
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.
