  • Ball Mill Parameter Selection & Calculation Power

    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 andFor mineral processing project, after blasting, crushing and screening system is always the first stage to reduce the big raw ore lumps to proper small particle size for following mill grinding system Normally to reduce the big ore lumps to smallCrushing&Screening System For Mineral ProcessingScreening Area = U / (A x B x C x D x E x F x G x H x J) • E: Wet screening (10 – 125) • F: Material weight (30 – 150) lbs/cuft • G: Open area of media • H: Shape of opening (100 – 120) sqshortlong • L: Accuracy (70 – 170) Application Example U: Required screening area (Square feet)Principles of Screening and Sizing
