The compact twin-screw side feeder enables dosing from the side of fillers and additives in powder or pelletized form, or of cut glass fibers. The co-rotating screws are largely self-cleaning and force-feeding.
The compounder can be mounted on the extruder using a connector housing on any location on the process part where the feed for the above-named materials is sensible.
| Construction: |  |  |
| - | | Transfer gearbox |
| - | | Main drive unit |
| - | | Single housing with optimized opening geometry, providing for partial aeration of the bulk material and consistently high fill levels on the screw |
| - | | Two screw shafts with screw elements |
| - | | Pivoting base frame screwed directly onto the ZSK base frame |
| - | | As an option, a moving base frame on rollers |
| Advantages: | | |
| - | | Increased output through higher drive output and increased speed |
| - | | The self-cleaning sealed profile of the twin-screw compounder screws transports the product and passes it with no clearance volume into the ZSK spirals |
| - | | Small space requirement due to short, narrow compact construction |
| - | | The housing is equipped with captive C-washers, which facilitate rapid mounting and disassembly of the twin-screw compounder from the hot ZSK |
| - | | The screwed-on pivoting base frame enables the twin-screw compounder to be connected to at least 2 neighboring ZSK housings. |
