Double slide flat continuous screen changer for masterbatch extrusion machine
GM-DSP series
In comparison with the double pistons continuous screen changer, the GM-DSP series double slide flat continuous screen changer allows a quicker screen change. This advantage is
based on the optimized volume of filtering chamber, which minimized the
duration of the venting procedure.The new sealing system allows the operation in extrusion lines with high pressures.
In masterbatch production process, consider about the change of color, we need to clean the extruder everytime when we need to change the color of the pellets, so it requires the chamber of the screen changer no any dead spots, and the raw material will not be residual in the dead spots.
The features of the chamber /flow channel of this kind of double slide flat continuous screen changer is no geometry dead spots.
So this kind screen changer now is widely used on the master batch extrusion line for melt filtration.
This GM-DSP series continuous screen changer/ melt filter is consist of
The main body of the screen changer
Hydraulic unit with accumulator
Electrical controlling pack
Characteristics of GM-DSP series continuous screen changer/melt filter
Two round removable breaker plates on each 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 400bar(40Mpa) not impact the high performance.
The filtration screen area covers from 100cm² to 980cm², depending on the size, fit for output range from 100kg/h to 3700kg/h.
Benifits of this kind of dual plate continuous screen changer for plastic extruder
