A grinder includes a grinding table rotatable about a first rotational axis and at least two grinding rollers. Each of the at least two grinding rollers is arranged for rotation about a second rotational axis such that ground material can be comminuted between the grinding table and the grinding rollers during operation. A sensor arrangement can detect a change in inclination of the grinding table beyond a given threshold value.
