Abstract: 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) due to the abrasive action of the ore pulp residing inside the mill and due to the action of the grinding elements during the operation, and which in certain cases also generates obstruction of the slots (4) due to the jamming of said grinding elements inside the slots (4) while the mill is running, and said grate (1) has 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), wherein said system includes: a sensor (16) located on the external surface (7), and said sensor (16) is connected to a sensor adaptor unit (17); a wireless transmitter (18) connected to said sensor (16), and said transmitter transmits the signal from the sensor (16); a wireless receiver (20) receiving the signa

Abstract: A system and a method is provided to measure the material discharge from a mill for grinding one in a real time. The system includes at least a strain gage located on at least one insert positioned in a pulp lifter or discharge cone. The strain gage is connected to an adaptor unit. A wireless transmitter is connected to the adaptor unit to transmit signals from the strain gage to a wireless receiver. A signal reader is connected to the wireless receiver to process the signal.

Abstract: A real-time monitoring system to monitor the wearing in the thickness of the ribs of a grate of a SAG mill. The grate can have a screening surface that includes a pulp lifter and an external surface that is not exposed to impacts, and can also include a central trough where the supporting elements fit and which allow securing the grate inside the mill through fitting bolts. The system can comprise: a sensor (accelerometer or strain gage) located on the external surface in which the sensor is connected to a sensor adaptor unit; a wireless transmitter connected to the sensor to transmit the signal from the sensor; a wireless receiver for receiving the signal from the wireless transmitter; and a signal reader connected to the wireless receiver which processes the signals received from the sensor.

Abstract: A system and a method to measure the material discharge from a mill for grinding ore in real time, wherein the system includes: at least of a strain gage (16) located on at least one insert (13), where said insert (16) is located in the pulp lifter (8) or discharge chute (9), and wherein said strain gage (16) is connected to an adaptor unit of the strain gage (22); a wireless transmitter (19) connected to said strain gage adaptor (22), wherein said transmitter transmits the signal from the strain gage (16); a wireless receiver (20) receiving the signal from the wireless transmitter (19); and a signal reader (21) connected to said wireless receiver (20) which processes the signals received from the accelerometer.
