screen changer for film or sheet line

Batte has been designing and manufacturing screen changers, including automatic and continuous solutions for plastic extruders. Whether you are processing highly contaminated, post-industrial or post-consumer plastics, or are committed to filtering clean plastics to ensure zero contamination, screen changers are a key element in your extrusion line for extruders from 30 mm to 600 mm in diameter.

Screen changer for film plant is simply a product used to filter out foreign particles and contaminants when plasticizing material flow filters, but is supported by an alloy porous plate that is mounted on a plate or column carrier. The carrier can be moved so as to switch between the working position of a system and the off-line non-working position. The screen changer can be installed on any new or existing extruder, melt pump, reactor or other extrusion line.

screen changer for film or sheet line

　1、Manual screen changer 

　A manual screen changer, as the name suggests, is a direct manual switch of the screen changer. Manual screen changer has the advantages of compact size and low cost, but its shortcomings are also obvious: the screen changing speed is slow, usually need to stop to change the screen, and the screen diameter is generally below 100mm due to the friction resistance and sealing performance.

　2、Hydraulic automatic screen changer 

Hydraulic automatic screen changer hydraulic automatic screen changer, is relying on the complex structure of the hydraulic station to switch back and forth to change the screen plate or screen column. Hydraulic automatic screen changer has the advantages of compact size, good back pressure sealing, rapid screen changing speed, etc. Its shortcomings are relatively more acceptable: higher cost and complex hydraulic structure. 

3、Net belt type automatic screen changer 

　Mesh belt type screen changer This series of filter consists of a 10m or 20m filter mesh belt, heating and cooling series and electric control system. No external power is needed, relying on the pressure driving device to automatically control the screen changing. No fluctuation of material flow and no deformation of products during screen changing. Suitable for: pp, pe, abs, ps, pmma and other plastic melts, widely used in the production of various films, plates, sheets, high quality, fiber, drawing, granulation and other long process products.
