Drum mills by SIEBTECHNIK TEMA - Comminution

Drum mills have a horizontal grinding drum rotating around a fixed center of rotation. Located in this cylindrical working space is a grinding-media filling, which is tumbled by the rotating grinding drum. The material fed is pulverized by the freely moving grinding-media primarily through pressure, impact and shearing action.
