Customized comminution

Dec 11, 2018· Effective and efficient comminution in AG (autogenous), SAG (semiautogenous) or ball mills means higher volumes through the mill and a finer product, leading to improved recovery. A poorly designed mill liner, however, can reduce the efficiency of the entire process, particularly if the liner wears quickly or unevenly.
