ZS-B twin screw side feeder

Our ZS-B twin screw side feeder enables the side feeding of fillers and additives in powder or pellet form or cut glass fibers into the processing section of the twin screw extruder. The ZS-B features the self-cleaning cleaning profile of the twin screws and product feeding into the screw flights of the extruder without stagnant zones. Very little space is required for the side feeder thanks to its compact design.

The side feeder can be mounted anywhere on the extruder’s process section in conjunction with a connection housing. C-clamps on the barrels allow fast assembly and disassembly.

In the standard version the ZS-B comes with a base frame on castors. Optionally it is mounted on a swivelling base frame which is bolted directly to the extruder’s machine bed. This solution provides extremely easy handling. It also allows the connection of ZS-Bs directly to adjacent barrels of the process section.
