Ceramic balls were used to ball mill the reinforcing fragments. For the selection of ball-milling process parameters (B.P.R., milling-speed and milling-time), numerous experiments were conducted. Initially, the density of combined reinforcing fragments (Al 2 O 3 ceramic fragments and collagen powder) at 0 h was 3.725 g/cm 3.

The life of the magnetic mill liner depends on the discharge type, mill diameter, ball size, magnetic permeability of ball and magnetic mineral content in feed. It has been observed that the MML lasts two to three times longer than rubber or metallic liners. The performance of the metal magnetic liner is consistent during the period of its life.
