FEDDEM Additional Modules

Robust Continuous Operation

Side Feeders and Side Venting / Degassing 

FEDDEM offers a range of auxiliary devices for ensuring smooth continuous performance of feed and degassing openings in the processing section. These devices are equipped with twin-screw discharges and frequency-controlled drives. Various speeds and screw pitches as well as a selection of metallurgies for abrasion and/or corrosion resistance allow to adapt these devices to individual process requirements.

FSB side feeders ensure uniform delivery of a metered stream of additives, fillers or reinforcing materials into the process. The FSV side vacuum degassing unit prevents extraction of product through the vent port in vacuum-sensitive degassing processes. It keeps the degassing opening in the processing section reliably and permanently open. The FSE side venting unit is a process relevant component that is only available from FEDDEM. It supports atmospheric venting when feeding fillers of low bulk density and reduces the exit of dust through the vent port. The unit can easily be converted for use as a side feeder. In some applications the use of FSV and FSE units allows for increasing the throughput rate by more than 30 %.

FEDDEM was the first machine manufacturer to design convertible versions of the FSB, FSV and FSE units and to supply them with optional conversion kits as early as 2012.

 

Flexibility and Cost-Efficiency

Processing Length

FEDDEM Extension

The FEDDEM Extension unit (e.g. 10 L/D long) allows for easy modifictaion of an extruder´s length to match the requirments of an individual process. Changing the processing lengths just takes a few hours, This offers the option of adapting the processing length of an extruder from a compounding application to large-volume venting / dgeassing or to reactive processing. Subsequent retrofitting of FEDDEM extruders to a longer processing length is an option and entails substaintially lower investment costs compared to sourcing an additional extruder. 

The extension is an already pre-mounted stand-alone module for quick-fix to the last barrel segment of the extruder. The electrical connection is established via quick disconnect couplings and when prepared at order placement the required control hard- and software extensions are already built into the extruder´s control cabinet.
