1. A method for determining a timing for replacement of a liner assembly within a comminution mill, the comminution mill having an external shell, comprising:
a) placing a sensor for directly measuring a wear profile of the liner assembly, the liner assembly including a body and a cavity open to the shell, and locating the sensor within the cavity;
b) registering a position of the liner assembly within the comminution mill, whereby the position of the liner assembly within the comminution mill is known;
c) storing the position of the liner assembly using a non-transitory memory associated with the comminution mill; and
d) monitoring an output of the sensor to determine the timing for replacement of the liner assembly based on the wear profile, and wherein the sensor transmits ultrasonic waves within the body of the liner assembly to determine a depth of the body for comparison to the wear profile.
