Brabender Technologie, Duisburg, Germany, has launched a new line of feeders designed specifically for handling pellets. The new DS Series is available in a choice of four sizes and is characterised by a simple design that concentrates on essentials.

 “Our main goal in launching this equipment is to reach out to compounders such as those specialising in films or textiles,” explained Jürgen Knez, developer of the DS line. Pellets are typically a simple material and can be fed using spiral screws requiring no additional agitation. “When designing the new line, we therefore concentrated on creating a feeder featuring only a few easily accessible components, a design so simple and easy to handle.”

At the design stage Knez focused primarily on applications, which is why the DS is available in two versions. “We have developed two different versions for various customer applications: the S version for continuous operations involving one material and the E version for frequent product changeovers.” The difference between them can be explained by the way the motor and screw are configured. On the DS-S, the standard version, both components are linked together. This is ideal for long-term feeding. For product changeovers and cleaning, both can only be removed together.

The enhanced DS-E version features a different design. “When a screw is being replaced or the device is being cleaned, the motor remains in place and is only shifted to allow the screw to be removed from the rear.” The slide gate and the tight pipe connection which allow the hopper to be emptied completely, are also practical details that make bulk material changeovers and cleaning easier. The DS-E is therefore ideal for various pellet feeding processes that involve frequent product changeovers. The new feeders will be featured on the Brabender Technologie stand at POWTECH (Hall 4, Stand 237). www.brabender-technologie.com
