Abstract
In a method for detaching a charge () which is stuck to the inner wall of a grinding pipe (), the grinding pipe () is rotated in a targeted manner such that the charge () that is stuck is removed from the inner wall of the grinding pipe () as a result of multiple modification of the rotational speed of the grinding pipe () and, optionally, as a result of abrupt braking of the grinding pipe (). Generally speaking, the material-dependent maximum angle of rotation F of the grinding pipe is not exceeded in order to avoid the charge that is stuck from falling in an uncontrolled manner. The invention supercedes labor-intensive and protracted methods for detaching such charges () since the tasks can be carried out by the same motor of the drive device () which is used to drive the grinding pipe () during the grinding process.
