摘要

The grinder has an outer body (1) and inner body (3). The inside face of the outer body and the outside face of the inner body are shaped to match that of the grinding rollers (2). The diameter of the rollers changes at least in the compensating region between the outer body and inner body along their shafts (10) uniformly corresponding to the distance between the outer body and inner body. The grinding rollers are mounted displaceable in order to compensate wear.
