Sidefeeder SF

Universal applicable Side Feeder SF

The latest development of COMTEC is the Side Feeder type SF. It is especially designed for delicate handled bulk materials. An extremely large feed port in relation with a special executed screw geometry avoids back-up's in the feed hopper.

The axial heavily beared corotating twin feed screws reliable feeds in the bulk materials and introduce it consistently into the extruder's melt stream. For cleaning and maintenance reasons the Side Feeder can be disconnected very quickly from the extruder by easily accessible quick clamps.

As an option the Side Feeder cylinder is heat- / coolable by liquid. Under demanding wear & tear conditions the feed screws can be made out of high wear resistant screw elements as well as the cylinder can be executed from extremely wear resistant bimetal.
