Abstract

An example method for estimating a wear profile of a consumable wear product used in conjunction with the processing of ore includes obtaining historical data related to wear of the consumable wear product, building a historical wear model based on the historical data, and obtaining a current single measurement point for the consumable wear product. The method includes extrapolating an estimated wear profile using the current measurement point and the historical wear model, and estimating a performance characteristic based on the estimated wear profile.

Claims

1. A method for estimating a wear profile of a liner assembly of a grinding mill that processes ore, the method comprising:

building a historical wear model based on historical data from the grinding mill;

obtaining a current single measurement point for the liner assembly;

extrapolating an estimated wear profile using the current single measurement point and the historical wear model; and

estimating a change-out date for the liner assembly based on the estimated wear profile.

2. The method of claim 1, further comprising estimating a wear rate of the liner assembly.

3. The method of claim 1, further comprising estimating a consumption rate of the liner assembly.

4. The method of claim 1, further comprising estimating a through put for the grinding mill using the liner assembly.
