China Continuous Screen Changer for Plastic Recycling Machine

Continuous screenchanger for plastic recycling machiner
The GM-DP-R series continuous screen changer/melt filter now is widely used on the plastic recycling machine, it makes a high efficient that no material leakage or product disruption.

This series of continuous screen changer is designed to work with two channels in the housing of the screen changer. there is a screen cavity on each bearing piston, and a screen pack on each screen cavity. they work at the same time. when screenchange is required, one screen is working, while the other one is changed , thus the replacement without machine halt is ensured and no interrupt of the melt stream or the production.

Features included
Continuous operation means no machine shut down or production intrerrupt
Flow channels have very good flow characteristics, no material buildup in thechannels
Three steps of gas venting system
inside and outside heating at the same time
Customized design
Benefits of this extruder polymer continuous screen changer
Increased production
Reduced downtime & scrap
Leak-free operation
Increased filtration area
Reduced inlet pressures
Accurate, repeatable screen changes
Reduced maintenance
