Features of this kind of GM-DP-E series of dual bolts continuous screen changer with elongated screen pack for extrusion machine
Two elongated /oval removable breaker plates on each bearing piston
"Continuous type" means operation of screen change without machine halt or disruption of melt flow.
Equipped with three steps of gas venting system
Fit for almost all kinds of polymers
Flexible installation ways
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.
screen change proces
The screen changer and gas venting process of this kind of Dual column continuous screen changer with enlarge enlongated screen pack
one rod is pushed out by hydraulically
the blocked filter screen pack is removed and replaced by a fresh one
the rod is pushed into the housing of the screen changer
the other rods repeat the above steps
The gas venting systen begins to work when the rod is pushed into the housing of the screen changer, and the following picture show the process of gas venting of this type of dual rods continuous extrusion screen changer for polymer melt filtration.
