Below each crushing roll (5, 6) is provided a curved perforated screen (13).

The invention relates to a press roll (1) for a roll press, in particular for comminuting highly abrasive materials, comprising a roll body (2).

The configuration of the crushing roll can be advantageously changed by replacing the support plate(s).

The roller mill is peculiar in that it comprises means (10, 11, 12) for regulating the angular position of the roller (4) relative to the horizontal plane of the grinding table (3) during the operation of the roller mill.

Additionally, a crush roll (410) for dressing such a grinding wheel is disclosed.

The inventive method allows a used grinding roll to be reconditioned in a particularly time-saving manner while economizing material.

A method of fixing a position of a roller in a roller crusher is also disclosed.
