Planetary Ball Mills are used wherever the highest degree of fineness is  required. Apart from the classical mixing and size reduction processes, the  mills also meet all the technical requirements for colloidal grinding and have the  energy input necessary for mechanical alloying processes. The extremely high centrifugal forces of the Planetary Ball Mills result in very high pulverization  energy and therefore short grinding times.

The PM 400 is a robust floor model with 4 grinding stations.

Application Examples:

alloys, bentonite, bones, carbon fibres, catalysts, cellulose, cement clinker,
ceramics, charcoal, chemical products, clay minerals, coal, coke, compost,
concrete, electronic scrap, fibres, glass, gypsum, hair, hydroxyapatite, iron  ore,
kaolin, limestone, metal oxides, minerals, ores, paints and lacquers, paper,
pigments, plant materials, polymers, quartz, seeds, ...
