The ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.The drum of the ball mill (Pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction effects of the balls and the grinding material.
The grinding circuit comprise of two parallel lines, each consisting of a twin semi-autogenous (SAG) mill and a twin pinion ball mill. The mills feature two 7,500kW variable speed drive motors. The larger gyratory crusher and a secondary crushing circuit ensure the supply of higher throughput of fine feed (75mm) to the SAG mill.
