3 The Mixer Mill MM 400
The MM 400 of the Retsch GmbH is a laboratory device and is used for the preparation of
samples.
The device enables fast crushing, grinding, mixing and homogenisation of soft, medium-hard,
hard, fibrous, elastic, and brittle materials in dry and wet condition up to a particle size of 8 mm.
The device is also suitable for the cryogenic grinding of sample materials.
Depending on the properties of the material and the grinding parameters, final fineness levels of
up to 5 µm can be achieved.
Due to the effective grinding process in a closed system, the device ensures a material-friendly,
analysis-oriented preparation of samples in the shortest possible time.
