learn more >In the plastic extrusion production process, plastic melt will produce some decomposition products after a long period of plasticization. At the same time, the raw material itself also contains some impurities. The existence of these impurities not only affects the quality of the product, but also and it affects the continuity and stability of production. The hydraulic screen changer is set between the screw head and the extruder head to filter out impurities and foreign matter in the plastic melt to obtain a pure melt. The hydraulic screen changer relies on the hydraulic station to switch the screen or the screen. The non-stop screen changer is generally composed of the screen changer body and the filter screen. It is composed of perforated plate, plunger and heater. The high-efficiency hydraulic screen changer with automatic backwash function sold by Batte melt pump is very suitable for the recycling and processing of waste plastics.
hydraulic screen changer configuration
1. What is the processed material, PP/PE/ABS/PET/HDPE/LDPE? Is it new material or recycled 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 product, plastic pipe or sheet, pellets, film?
5. Do you require continuous or discontinuous process?
According to the technical feedback, we will suggest that screen changer more suitable your processing requirement.
What are the benifits of screen changer on extruder?1. Improve the quality of the final products
2. Greatly improve the plasticizing of the raw material
3. Make the product structure more homogeneous and product surface smoothness.
4. Protect the down stream equipments, such as melt pumps and the extrusion dies.
