Grinding experiments were performed in a steel mill having dimensions of the Bond ball mill (305 mm × 305 mm) with smooth inner surface. A torque transducer (Magtrol, TMB 308/411) was mounted between the motor (Asynchronous AC-0.37 kW) and the mill drum by using flexible couplings (Rexnord, BSD-966-62-000 CBC Single) in order to measure the torque drawn by the mill avoiding efficiency losses

Abstract The kinetics of slowing down of breakage rates for fine wet grinding of 20×30 mesh quartz fraction was investigated as a function of slurry concentration in a laboratory batch ball mill. It was discovered that the slowing-down effect occurred to all particle sizes in the charge and at any slurry concentrations even for very dilute conditions. The slowing-down factor was defined and

Therefore, the research in fine grinding has gained more importance, especially, in submicron grinding. In the previous paper, a series of wet grinding experiments using inorganic powders by a stirred ball mill were performed. The grinding consumption power was measured, and the grinding rate constant, K, in the grinding kinetics equation was

Laboratory batch wet ball milling tests of quartz and chlorite were carried out for four feed size fractions (− 2 + 1.19 mm, − 1.19 + 0.5 mm, − 0.5 + 0.25 mm,-0.25 + 0.15 mm). The results showed that both quartz and chlorite demonstrated the first-order breakage behavior in the feed size range investigated.

The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the shell is 5′ inside diameter and

The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions, with about 70% solid mixture in water. This procedure maximizes ore production and minimizes power consumption.
