Double Piston Continuous Screen Changer for Plastic Extruder


Working principle of this GM-DP-R series continuous screen changer

As the polymer melt enters the main body ofthe screen changer, the melt stream is divided equally and flows into the two channels ,go through the two breaker plates, and the impurities are intercepted by the screen mesh, and when screen changing is required, one of the pistons with blocked screen pack is pushed out by hydraulic unit , and the other is still on the working position, we replace the fresh screen and then the piston with new screen is pushed into the working position, at this time, the air bleeding system also begin to work.  The other piston screen change is the same with above.  This type of continuous screen changer maintains a continuous melt flow.

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.
