Drive systems
For more than 25 years, VISCOTHERM AG has taken separation technology forward through continuous innovation with its ROTODIFF decanter centrifuge drives. This development is typified by exceptional flexibility of the equipment, adaptation to widely varying operational conditions.

Fundamentals
The typical feature of all VISCOTHERM drive systems is their exceptional adaptability to widely varying operational conditions. The fundamental criteria are variable scroll speed and bowl rotation speed (option). These two parameters are among the most important in the decanter centrifuge technology.

Bow speed variations of the decanter have decisive bearing on:

the separation speed (g-force)
die Sedimentsetzung

Differential speed changes of the scroll have decisive bearing on:

the direct impact on solids delivery and hence solids throughput
solids residence time
solids filling level in the bowl

These parameters directly influence the volume of solids which can be separated, the dry content of the solids and hence also the total performance of a decanter centrifuge.
