Ball Mill Motor Power Draw Sizing and Design Formula

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

Calculation of Top Grinding Media Size -Ball Sizing

The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond (1958) or Azzaroni (1984) or by using special batch-grinding tests interpreted in the content of population balance models (Lo and Herbst 1986). The effect of ...

Principles of Ball Mill Grinding | Mill (Grinding) | Paint

In steel ball grinding, many operators, especially in the paint industry, are satisfied to run with a smaller ball charge ranging as low as one-third the volume of the Mill. They find the smaller charge gives them the required grind within allowable limits of grinding time and the …

Kinetic study of ferronickel slag grinding at variation of ball …

The objective of this paper is to investigate the effect of ball filling and ratio of feed to grinding balls on the kinetic of grinding of ferronickel slag in a laboratory scale ball mill. The experiments were started by crushing the ferronickel slag samples using a roll crusher to produce −3 mesh (−6.7 mm) product. This product, after sampling and sample dividing processes, was then used ...
