single screw extruder with self-cleaning filtration system

Short Description:

PURUI company make and design a new type of self-cleaning filtration system adopts the latest research and development technology, which can realize non-stop cyclic extrusion, especially suitable for heavy pollution plastic granulation. The newest filtration system can treat and remove up to 5% of impurities in the melt. Separable impurities include paper, wood chips, aluminum, non-melting plastics, and rubber.

The screen changer is a manual or automatic switching device consisting of one or more filters, which is used to filter out foreign particles and impurities when plasticizing material flow filters. As we all know, the cleanliness of the recycled materials and the technological use of the final regenerated particles determine the filtration technical standards of the filtration system. For different melt filtration loads, the conventional non-stop single-plate double-station or two-piston double-station screen-changing filtration system is applied to achieve excellent melt filtration performance.

The traditional screen changer needs to replace the dirty metal filter in time, while the newest system has continuous filtering performance and automatically removes impurities on the surface of the alloy filter plate, with an effective accuracy of up to 120 mesh. The advent of the PURUI newest self-cleaning filter has realized a more efficient production of pelletizing lines with an output of more than one ton per hour.

this new design equipped with compactor/cutter, single screw extruder, hot watering cutting system, self-cleaning system. which is automatic scraping action to ensure continuous self-cleaning of the filter screen, and it can reduce the waste of melt when the impurities are discharged.
