Moreover, the steel balls wear continuously while grinding the ore block and become smaller and smaller until they fail, resulting in a substantial consumption of grinding balls. Significance of ball mill balls. Using too many grinding balls in the ball mill will cause the steel balls to overlap, which will reduce the grinding effect.

Industrial tests of grinding balls 40 mm in diameter of hardness group IV under Southern Mining and Processing Plant conditions have shown that the specific consumption at 0.124 kg/ton of concentrate is lower (8.83%) than for grinding balls of hardness group III used currently produced by DMKD or Azovstal.
Details
Steel consumption of balls is spread out over an even greater range. Some indication as to media consumption can be obtained from power consumed in grinding. For example, balls or rods will generally wear at a rate of about 1# for each 6 or 7 kilowatt hours consumed per ton of ore.
Details
The load acted by grinding balls on lignocellulosic biomass is considerably higher, compared to the conventional ball mill and planetary ball mill. Important factors affecting the impact forces acting on the powders are the rate of milling, vibrational frequency, the amplitude of vibration, and the mass of the grinding balls [ 33, 47, 48 ].

suggested), depending on size of balls and ore being tested. • Ball surface wear rate is approximately constant, but with variations due to hardness, and other factors. Consumption is closely related to total ball charge surface area. • A useful guideline for make-up ball size for a new circuit was provided by Bond (1958).
