Gyratory Crusher Wear Monitoring Using Laser Technology

Crushing has proven to be of fundamental importance in mine mill integration at Highland Valley Copper (HVC). Highland Valley Copper has achieved large throughput and good quality control through the gyratory crushers by proper blast design and better gap control. The next step, in optimizing the mine mill relationship, is evaluating the crusher liner wear and its shape influence on performance and product size reduction. To do this a laser measurement device has been developed and data is being recorded on the concave and mantle liner wear. This paper will outline the work to date and indicate specific objectives of the work.
