The grinding setup refers to the socalled Malmberget method used at LKAB, characterized by a subsequent circuit of rod and ball mill grinding. The highest P 80 values were obtained by grinding only in the rod mill for 10 min (step A). Ball mill grinding for 25 min (step B) and 35 min (step C) gave a very narrow range of P 80 values.

The experimental results showed that the AbbottFirestone curve can evaluate the lifter surface topography. The wear rate of the lifter specimen is increased first and then decreased with mill speed and grinding media size. Increasing ball filling will increase the wear rate, and the grinding media shape of ball has a maximum wear rate.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

These studies have been carried out to compare the grinding characteristics of different morphological mineral matters. Coal, dolomite, manganese and iron ores samples were ground using a ball mill in different grinding conditions (dry and wet) and at different critical speed (R 45%, R 70% and R 90%) during wet grinding.

Xiao et al. [2] investigated the iron grade and recovery of fine grained magnetite ground by a stirred mill and ball mill. They found that the stirred mill was more beneficial for grinding P80 1030 μm minerals to liberate more valuable minerals and the grade of iron concentrate was % higher than that of ball mill.

Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
