screen changer/ filtration system for plastic extrusion
The Continuous Screen Changer allows for filtration of most all polymers without interrupting production during a screen change. The Continuous Screen Changer consists of two screen bolts with each containing a filter cavity. When a screen change is required, one of the bolts is moved out of the housing while the other remains in the operating position. The dirty screen pack is removed and replaced with a new one. The bolt is then moved back into the housing to its venting stages before resuming operation. These steps are then repeated for the other bolt. This concept allows for continuous filtration with no interruption or loss of production.

Application
1. Used for the production of plate, sheet, cast film, pipe, granulation and so on.

2. Applicable to the production line of colossal, adhesive, coating and finishing materials and other blending agent products, used for filtration of the material mixture, filtering screen replacement available without machine halt.
