Batch dosing device, Cx-Series

With integrated vacuum conveying
Gravimetric – conveying, dosing, weighing, mixing, extracting and controlling in a single device
For plastic granulate, additives and ground materials


The Cx-series has been designed for a capacity from 100 kg/h to 1000 kg/h. Its unique, compact design saves space to ensure perfect dosing and mixing results. Whether granulate or ground product – all materials are homogeneously mixed.
Individual components from 0.5 to 100 % are metered into the weighing hopper with sliders. At quantities of 0.05 % to 0.5 %, metering is by a drum dosing station (WD).

Sliders with special seals ensure both an exact metering accuracy and effective sealing for filling the dosing stations.

There is no need to disassemble the feeders for cleaning. Thus maintenance and cleaning become a matter of minutes.
