A method for treating viscous-pasty compositions in a housing (1) with kneading elements (2, 3), at least one kneading element (2, 3) being monitored, comprising the steps of:
- generating a control signal with the aid of which the state of the kneading element can be clearly assigned by the monitoring, with the control signal being generated from a drop in the pressure of a pressure medium and, when there is a drop in pressure, pressure is supplied in order to maintain a predetermined pressure of the pressure medium.
A device for treating viscous-pasty compositions comprising a housing (1) having at least two kneading elements (2, 3), at least one of the kneading elements (2, 3) being connected to a monitoring device (8) and another kneading element (2) being passed through at least partially by at least one channel (14) which is connected to a pressure medium source (15), the channel (14) is connected with the pressure medium source (15) by a valve block (6), and a pressure sensor (16) assigned to the valve block (6) or to a pressure medium line to the pressure medium source (15).
