REAL-TIME MONITORING SYSTEM TO DETERMINE WEARING IN GRATE RIBS IN SEMI-AUTOGEONOUS MILLS, TO DETECT THE CONDITIONS OF JAMMING GRATES DURING THE OPERATION, AND TO DETECT WORKING CONDITIONS UNDER DIRECT IMPACT OF THE BALLS ON THE GRATES TECHNICAL FIELD OF THE INVENTION

摘要

A real-time monitoring system to monitor the wearing in the thickness of the ribs (5) of a grate (1) of a SAG mill (9) during the operation, having said grate (1 ) a screening surface (2) that includes a pulp lifter (3) and an external surface (7) that is not exposed to impacts, and also includes a central trough (6) where the supporting elements fit and which allow securing the grate inside the mill through fitting bolts (12). The system includes: an accelerometer (16) located on the external surface (7); a wireless transmitter (18), wherein said transmitter transmits the signal from the sensor (16); a wireless receiver (20) receiving the signal from the wireless transmitter (18); and a signal reader (21 ).
