Abstract (en)
The ball ring mill (99) has a grinder (1) with multiple grinding balls (4), which are guided in a mill track between a grinding ring (2) and a pressure ring (3). The grinding balls are movable along the mill track due to difference of rotational speeds of the grinding and pressure rings. A sensor system (11) is provided for contactless detection of the movement of the grinding balls, where the sensor system has expansion-measuring strips, a radiation source e.g. microwave source and light source, and a radiation detector e.g. microwave detector and light detector. The sensor system is inductive, capacitive, magnetic, optical, acoustic and electromagnetic proximity switches. An independent claim is also included for a method for monitoring a movement of a grinding ball in a ball ring mill.
Abstract (de)
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Überwachung der Mahlkugelnbewegung in einer Kugelringmühle (99), bei der Mahlkugeln (4) sich entlang einer Mahlspur (10) bewegen. Dazu ist ein Sensorsystem (11) zur berührungslosen Erfassung des Vorbeilaufens einer Mahlkugel am (4) Sensorsystem (11) vorgesehen ist. Durch Auswertung des Sensorsignals können Störungen im Betrieb der Kugelringmühle (99) festgestellt werden.
