May 16, 2009· The common wear rate determination method is to assume uniform wear profile for a liner and measure the profile at one cross section. But it has been shown that the wear profile of the liner is not uniform (Banisi and Hadizadeh, 2006).Thus, a new method was proposed and tested which measures the wear profile through building a 3-D model of liners after any given operating time.
