    22/01/2002  Fig. 1, Fig. 2, Fig. 3 show examples of the relationship between the mass fraction of feed size and grinding time using balls with a diameter of 20 mm and the materials of silica glass, limestone and gypsum, respectively. They exhibit almost linear relationships when plotted on semi-log graph paper, and it is possible to calculate the grinding rate constant K 1 of Eq.

  • Ball mill - Wikipedia

    A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

  • 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 ...

    The minimum size of grinding balls should be selected with caution since there will be a tendency for such balls to float out of the mill in a dense pulp (this is minimised by the use of a grate discharge mill). Also the smaller the media the quicker it will reach its reject size. For the first stage of grinding, media will generally be in the 4″ to 2″ size (in some cases as high as 5 ...
