WhatsApp: +86 18203695377A feature of ball mills is their high specific energy consumption; a mill filled with balls, working idle, consumes approximately as much energy as at fullscale capacity, during grinding of material. Therefore, it is most disadvantageous to use a ball mill at less than full capacity. Ball mills have the following advantages:
WhatsApp: +86 18203695377The aim of this work was to optimize the ball mill based refining process of chocolate, in terms of refining time and energy consumption. Experiments were planned following a central composite design ... Analysis of ball mill grinding operation using mill power specific kinetic parameters. Advanced Powder Technology, Volume 25, Issue 2, 2014 ...

WhatsApp: +86 18203695377Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
WhatsApp: +86 18203695377Models for the prediction of the power drawn by ball, semiautogenous and fully autogenous mills have been developed and cited in the technical literature ( Turner, 1982, Austin, 1990, Moys, 1993, Morrell, 1996 ). However, none of these models considers the feed size distribution as a design variable.
WhatsApp: +86 18203695377Another argument for the usage of beater mills over ball mills is the low number of collisions with sufficient energy to cause breakage that occurs in the later, as presented in (Powell and McBride, 2006). ...
