A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grinds material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

Some of the major findings from the study were as follows. HPGR energy consumption (kWh/t) was 38% of the ball mills. With all the different auxiliary equipment, HPGR total circuit energy usage was still less than 50% of the ball mill circuits. Fines removal from HPGR feed increased grinding efficiency in the compression zone by 25% to 30%.
