  • Ball Mill Parameter Selection CalculationPower

    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 21 CONCLUSIONS Continued In the present work equations were also derived giving zthe ball-mill power drawP as a function of its dimensions internal mill diameter D and length L zthe ball-mill power drawP as a function of the feed D f (mm) and the product size d (mm) the Bond work index w i (kWh/short ton) and the mill throughput T (short ton/h) zthe ball-mill dimensions (D and L) when

  • Calculate Ball Mill Grinding Capacity

    The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.
