Product Description

Double piston continuous screen changer with large filtration area for plastic extruder

This GM-DP-L series  continuous screen changer/ melt filter is consist of

• The main body of the screen changer
•  Hydraulic unit 
• Electrical controlling pack(this part is optional choice by customers)

This GM-DP-L series Large filtration are continuous screen changer for high output recycling 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. And this kind of continuous screen changer now is widely used for the hot melt adhesive, high output plastic recycling machine.

 

Characteristics of  GM-DP-L series continuous  screen changer/melt filter

• 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.
