LINER ASSEMBLY FOR ORE GRINDING MILL

Abstract

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.

Description

Claims

1. A method for determining the timing for replacement of a liner assembly within a comminution mill, comprising: a) placing a sensor for measuring a wear profile within a liner assembly;b) registering the position of the liner assembly within the comminution mill, whereby position of the sensor within the comminution mill is also known; andc) monitoring the output of the sensor to determine an appropriate time to replace the liner assembly based on the wear profile.

2. The method of claim 17, wherein the sensor is an ultrasonic sensor.

3. The method of claim 18, further comprising registering the position of the liner assembly by including an RFID tag with a unique identification information in the liner assembly.

4. The method of claim 18, further comprising transmitting the output of the sensor to a computer for comparison to a stored predetermined wear profile.
