Biopolymer Production Double Piston Screen Changer

What is screen changer/melt filter?

Screen changer/melt filter includes one or more filter devices. When the polymer fluid flow enters the filter device, the contaminants in the melt is blocked in one side of the filter. The filter is supported by a breaker plate, while the breaker plates are installed in the support carriage; support carriage parts can move, stay in the work place or non-working position.

How to choose a suitable screen changer/melt filter?

As for screen changer, we need these following information:

1. What is the processed material, PP/PE/ABS/PET? Is it new material or reclaim material?

2. Is the extruder single screw or twin screw?  What size is the screw diameter?

3. Production capacity (Kg/h)?  Max operating pressure?

4. What is the finial products, plastic pipe or sheet, pellets?

5. Do you require continuous or discontinuous process?

According to the technical feedback, we will suggest that screen changer more suitable your processing requirement.

Batte has especially manufactured melt pumps, screen changer, melt filter  and loss in weight feeders over than ten years. So we has accumulated abundant experience on the application technique of melt pumps.Recently, according to to the development trend of melt pumps application over the world, especially in the field of precise plastic extrusion. We have done extensive research on the pump operation performance, practical function, equipment structure and control technology and achieved regular achievements.
