Plate Type Continuous Screen Changer
This GM-R series of screen changer consists of four independent same size breaker plates, each with the same diameter . These specially treated alloy steel breaker plates has superior sealing ability and durability. This type of screen changer has slight melt pressure fluctuation during screen changing period, thus guarantee a continuous and stable extrusion production.
Breaker plates move in the same direction one by one, improved filtration performance, convenient to clean.
Equipped with preheating and ventilation design to minimize the effect of possible temperature, pressure, melt flow fluctuation on polymer during screen changing process.
Working principle of this kind of screen changer
This GM-R series continuous screen changer/ melt filter is consist of
The main body of the screen changer
Hydraulic unit
Electrical controlling pack
Characteristics of GM-R series continuous screen changer/melt filter
Four round removable breaker plates on the slide plate
"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 500bar(50Mpa) not impact the high performance.
The filtration screen area covers from 38cm² to 314cm², depending on the size, fit for output range from 500kg/h to 1100kg/h]
