In order to enlarge the filtration area of the screen changer, GMACH  design this GM-DP-E series continuous screen changer with enlongated screen  pack, you can compare the breaker plate of this type and the GM-DP-R series round breaker plate
 
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 process
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.

Tips for customers
How to choose a most suitable type of screen changer for your extrusion line ?
After the equipment supplier making a size recommendation and then you should perform your own analysis to confirm appropriate sizing. That way, you will have the advantage of independent analyses and, best of all, there is no additional cost.
Learn the difference between price and cost. Be sure to take into consideration all of the variables and look at all the factors to determine the real cost of ownership for the screen changer. Some of the hidden variables to consider may be:
Product quality.
Maintenance, time and cost of parts.
Process downtime and cost.
Life expectancy for the equipment and amortized cost of ownership.
Cost and availability of filtration media.
Pressure loss and effect on line output and product quality.
Operator safety.
Required operator intervention and labor cost.
If all of these and other factors are taken into consideration, you can choose the most suitable solution, and then you can expect a much better return on investment.
