The present invention provides a system and method for more efficient utilization of comminution mills. Sensors are provided in the liners placed within the mill shell. The sensors may include RFID tags, liner wear profile sensors (e.g., such as an ultrasonic sensor), an inertial sensor (preferably included both an inclinometer and an accelerometer, and an acoustic sensor, among others. When the liners are installed in the shell, the RFID tag is used to register the location of the liner within the shell. In operation, the information provided by the sensors is collected by a data transmission unit and sent by transmitter over the air to a computer having an antenna and receiver for such data. The data is correlated and the data is reviewable in real time while the mill is in running.
A system for monitoring the operation of a comminution mill, comprising:
The system of claim 10, wherein the sensor is an ultrasonic sensor.
The system of claim 10, further comprising:
The system of claim 12, further comprising a plurality of RFID tags having a unique identifier, where the individual RFID tags are associated with corresponding liner assemblies, and where the RFID tag unique identifier is transmitted with the first signals, whereby the wear reference values are associated to corresponding liner assemblies.
The system of claim 13, wherein one or more additional sensors are included in the liner assembly and generate second signals representative of mill operation parameters, the additional sensors selected from the group:
The system of claim 14, wherein the second signals are transmitted to the receiver and provided by the processor to a display device, wherein operation of the mill may be reviewed based on the second signal parameters in real time and changes to the operation of the mill may be made.
The system of claim 15, further including providing the first and second signals to a remote location.
