Comminution in a Material Bed
|
|
|
|
|
|
The High Pressure Roller Mill, also named Roller Press, consists of two rollers with the same diameter, wich are rotating
against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.

|
The bearing units of one roller can move linearly and are pressed against the material bed by springs or hydraulic
cylinders. The pressures in the material bed are bigger than 50 MPa. In general they achieve 100 to 300 MPa. By this the material bed is compacted to a solid volume portion of more than 80 %.
The High Pressure Roller Mill has a certain similarity to roller crushers and roller presses for the compacting of
powders, but purpose, construction and operation mode are different. - Schwechten, D. [2]
