Roller mills are suitable for fine grinding of soft to medium hard materials, specifically light, adhesive and temperature sensitive materials. The throughput rates vary from 100 kg/h to 80 t/h depending on mill size, material and its fineness.
Depending on the material, grinding and drying of material with a humidity of 35% (in case of clay) is possible.
The material is fed to the mill by a feeding device and drops onto the bottom of the lower mill housing. In front of each pendulum a rotary shovel is installed which picks up the material from the bottom and feeds it between the rolls and the grinding ring. Here the grinding of the material takes place.An air stream lifts the ground product from the lower mill housing, into a static or dynamic classifier mounted on top of the mill. This classifier can be adjusted to the required particle size. The separated coarse product flows back to the mill for regrinding. Fine material is drawn through the classifier and is sucked into a dust collector.
