Carrying out experiments in a mill, namely the ball filling j and the powder filling f c.J is the ball filling volume, which is the fraction of the mill filled by the grinding media bed eqn.1, while f c is the powder filling volume in the mill eqn.2 1 1 volume of solid balls j mill volume 1 c 1 1 volumeofsolidpowder f.Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 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 particle-size measurement device and size-control cyclones.

Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill.
Jun 01, 2018 Dry batch milling tests were performed in a laboratory scale ball mill measuring 30.2 by 28.2 cm. The mill specifications are given in Table 1. A constant ball load of 20 was maintained in all the tests with a ratio of 0.5 for binary and 0.33 for trinary ball mix.Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40 by volume, the rotation rate was equal to 85 of the critical speed. Balls were made from steel S4146, extra high quality, having hardness 62 2 HRC according to Rockwell.
1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of.Makokha et al. [20] reported that an increase in the ball mill volume loading tends to increase the slurry turnover time. It reduced the slurry pool volume subsequently lowering the mill discharge.
