TM 300 Drum Mill

Retsch | Sample Preparation - Inorganic, Sample Preparation - Organic

The TM 300 Drum Mill is used for the preparation of granules and powders.The grinding process is performed either in dry or wet conditions. The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process. Typically, a final fineness below 20 microns is obtained.

The drum mill consists of a gear motor mounted on a solid steel frame complete with outlet funnel and a set of separation screens plus sample collector. The TM 300 features a yoke and locking mechanism for easy access to the sample. The drum cover is easily removed for cleaning thanks to a quick release locking mechanism.

Adjustment of grinding parameters:
Parameters like grinding time or start and stop are set conveniently via the display. The following factors have an influence on the final particle size: Sample characteristics, maximum feed size and capacity. We will gladly support you in working out the most suitable configuration for your specific application.
