High performance double pistons screen changer for non-woven fabric production machine
Why do we need to use the screen changer/ melt filter on the non-woven fabric extrusion machine?
In nonwovens manufacture it is necessary to achieve a uniform spinning quality across all spin packs. Therefore, any in homogeneities must be removed before they enter the spinning beam. Moreover, process consistency regarding pressure and temperature is the basic prerequisite for an efficient production. Our GM-DP-R series double-piston continuous screen changer is widely used on spun bond and melt-blown nonwovens production lines.
This GM-DP-R series continuous screen changer/ melt filter is consist of
The main body of the screen changer
Electrical controlling pack
Characteristics of GM-DP-R series continuous screen changer/melt filter
Two round removable breaker plates on each bearing piston
"Continuous type" means operation of screen change without machine halt or disruption of melt flow.
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 56cm² to 520cm², depending on the size, fit for output range from 30kg/h to 1800kg/h.
