Methods and apparatus for continuous monitoring of wear in grinding circuits

A system for the continuous monitoring of wear is disclosed. The system comprises a grinding mill (100) having at least one grinding disc (106). At least one detector (141) is provided to the at least one grinding disc (106), and at least one sensor (120) is provided to the grinding mill (100) which is configured to communicate with the at least one detector (141) during operation of the grinding mill (100). In use, the at least one grinding disc (106) wears away and ultimately affects a function of the least one detector (141). The at least one sensor (120) is configured to monitor said function of the least one detector (141). When the at least one sensor (120) detects a change in the signal of the at least one detector (141), an operator is notified that maintenance or grinding disc replacement may be necessary.
