Abstract
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.

A grinder, comprising:
- a grinding table rotatable about a first rotational axis;
- at least two grinding rollers, each of the at least two grinding rollers being arranged for rotation about a second rotational axis such that ground material is able of being comminuted between the grinding table and the grinding rollers during operation;
- and
- a sensor arrangement configured to detect a change in inclination of the grinding table beyond a given threshold value.

A method for operating a grinder, said method comprising:
- measuring variables as the grinder is in operation to determine a tilt of a grinding table of the grinder from a specified position;
- comparing a change in inclination of the grinding table with a given threshold value;
- and
- outputting an alarm via a human-machine interface, when the change in inclination of the grinding table has reached, or exceeded, the given threshold value.
