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

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 ).
