Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones This is generally followed by a cone crusher A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh 45 m Instead of grinding the ore dry slurry is used as feed for rod or ball mills to avoid dusting.
The HPGRball mill circuit comprises a reverseclosed secondary crushing circuit prior to a closed HPGR circuit followed by a reversedclosed ballmill circuit with cyclones See Figure 2 The vibrating screen decks were set to an aperture size of 32 and 4 mm for the secondary crushing stage and HPGR screen circuit respectively.
When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only.
