of autogenous, semi-autogenous and ball mill grinding circuits[6]. Schnatz carried out a huge test program on a semi-industrial ball mill which operates in a closed circuit. He evaluated performance of a ball mill circuit by varying the L/D ratio, ball charge filling ratio, ball size and residence time and determined their optimum value[7].

below 0.25” are sent to the grinding section for further size reduction. The screen deck oversize, consisting of particles over 0.25”, is recycled back to SC-101. The Ball Mill, B-101, grinds the 0.25” ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles
validity of each theory within a certain particle size range. This study illustrated that Kicks law was applicable in the crushing range (above 1 cm in diameter) . Bond's theory was more suited to the particle size ranges involved in conventional ball and rod mill grinding (5 to 250 mm). Rittinger's law showed more _app1icability to the fine
rate at each screen size is calculated from a torque-mill test as in the example that follows. Torque mill solids load during test: 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. Mill speed: 35.2 rpm (65 percent of critical speed)
The ball mill is the key equipment to crush the material after being crushed. This type of mill is equipped with a number of steel balls in its cylinder as grinding medium. When the barrel rotates, the grinding medium is attached to the wall lining of the barrel due to inertial centrifugal force.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and
Besides particle size reduction, ball mills are also widely used for mixing, blending and dispersing, amorphisation of materials and mechanical alloying [1, 49, 51].
