Drum Mill TM 300 XL

Language:


The TM 300 XL 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 150 microns is obtained.

The 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 XL 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.

Function Principle

In a drum mill the sample (usually pre-crushed material) is placed inside the drum with the grinding media (grinding balls or rods) and subjected to external forces. The Ball Mill and Rod Mill Modules are used for fine grinding of solid matter by impact and friction, in wet or dry condition. The drum, which contains the sample and grinding balls or rods, rotates around a horizontal axis. Whereas particles break more easily when larger grinding ball resp. rod diameters are used, smaller diameters lead to a substantially higher final fineness.

The motor incorporates a solid-state controller with internal overload protection which is used to set and accurately control different drum speeds.
