Single stage balls mills, when processing hard to grind, large sized material incur an oversize inef fi ciency problem over and above the Bond oversize feed factor (EF4). Rod mills suffer from this ineffi ciency phenomenon and AG/ SAG mills mimic the same shortcoming. It follows that in order to obtain the specifi c energy (SE) to achieve a certain transfer size, based on the 80 .

· The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially. Interior of the drum uses the lifting plates. These plates inside the drum are responsible for picking the grinding material up to fall down again throughout the rotations. Repeated collisions between the steel balls and raw materials (ore ...

Ball mill is a cylinder rotating at about 7080% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Grinding media consists balls of 34 sizes (60mm30mm) in designed proportions with large sizes in feed end and small sizes in discharge end. About 27 to 35 % volume of mill is filled with grinding media. Equilibrium charge is that charge ...

Design features of grinding equipment (SAG, BALL and ROD MILLS) ... ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill ...

· Energy consumption for ball mills is a function of many factors: the physical properties of the ground material – its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc. Ball mills have low efficiency – no more than 15%. Energy is mainly consumed on the wear of grinding balls and mill housing, friction; heating the material etc.

Further tests were done, using samples from a platinum mine, namely the feed to a secondary mill (ballmill) and rounded pebbles from a primary AG mill. Grinding capacity was maintained over the range 030% pebbles, by volume, with savings in energy and ball consumption increasing progressively. At 25% pebbles, the saving in energy was 18% and the pebble .
