    摘要: A device for processing high-consistency fibrous material has a housing. First and second treatment tools in the housing are fastened to a base plate, have a rotationally symmetrical form, are arranged coaxially to each other, rotate relative to one another about a common axis and delimit a treatment gap through which the fibrous material radially flows. The gap width of the gap is varied by axially shifting at least one base plate of a treatment tool. In order to determine the minimum distance between the base plates, the oscillations are detected on the device and the distance between the base plates rotating relative to one another is reduced until the frequency and/or the amplitude and/or the change in frequency and/or the change in amplitude of the oscillations exceeds a limit value. The distance when the limit value is exceeded is determined as the minimum distance.
