suggestions to improve wear rate of ball mill liner

  • Modification of SAG mill liner shape based on 3-D liner

    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.
