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.

摘要： A reducing machine having an air cooled cutting discs is disclosed. The air cooled discs have cutting surfaces on both sides. The cutting surfaces have edges which are sharpened for cutting input material when the cutting surface is facing the cutting surface of the opposed disc. When the cutting surface of the stationary disc is facing the housing, the cutting surface acts as a heat sink to air cool the stationary disc and the mill assembly in general. Air inlets in the housing lid permit air to flow over the cooling surface of the stationary plate. Air inlets in the carrying plate permit the carrying plate to channel air flow over the rotating cooling surface. A damper restricts air flow over the air cooling surfaces to control the temperature of the reducing machine, such as during start up.
