The weight loss can then be used to calculate the specific wear rate (g/kWh) of the media. It is important to note that wear rates are often different for different materials and even different types of mills. For example, a ball mill typically has a higher wear rate than a rod mill. Operating conditions also play a role in determining wear rates.
