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.
1. SCF series disc-type self-cleaning filtration system
The new SCF self-cleaning filtration system makes non-stopping recycling extrusion, especially suitable to highly
contaminated materials re-pelletizing. Different from traditional screen changers, which requires timely change the dirty
wire mesh, the SCF system will present continuous filtering performance, and remove the contaminates from the surface of steel screen plate automatically. The SCF filtration system consists of hardened steel screen plate, rotating unit,hydraulic section, contaminates removing blades and discharging screw. SCF filtration system can handle and remove up
to 5% contaminates in the melt flowing, can separate the contaminates as: paper, wood, aluminum, unmelted plastic and
