DEVICE FOR MONITORING OPERATIONAL CONDITIONS OF A MINERAL CRUSHER

原文（中国語）

There is disclosed a mill comprising a motorized rotating drum having an internal cavity of the rotary drum; a lifter and grinding media located in the internal cavity for promoting breakdown of mineral; a bolt configured to hold the lifter to the inner surface of the rotary drum, one end of the bolt elongated to the full height of the lifter located in the internal cavity of the rotary drum, the other end of the elongated bolt located outside of the rotary drum; an acoustic sensor acoustically coupled to the elongated bolt for capturing acoustic waves carried by the bolt from the inside to the outside of the internal cavity; and a condition monitoring system mounted on the rotating drum communicating data to a base station. AI assisted condition monitoring of the acoustic signals, provides control parameters for safe operation of the mill, optimizing lifter wear and through put.
