In the case of frequent product and formulation changes as well as variable processes, batch mixers or discontinuous mixers are used.

They are suitable e.g. for gentle homogenization and in general for the pre-processing of solid mixtures, solid-liquid, and paste-like mixtures. They are also used for sterilization, breaking up agglomerates, pelletilization, initiating chemical reactions, and metering during product manufacturing.

Product range
