作用原理

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