Abstract
A method for treating in particular viscous, paste-like materials in a housing (1) with kneading elements (2, 3), in which at least one kneading element (2, 3) is to be monitored.
Claims4
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 and further comprising the steps of maintaining a predetermined constant pressure in the kneading element, and monitoring a through flow of the pressure medium to distinguish between normal leakage and breakage of the kneading element.
