Cement Mill Great Wall
The cement ball mill is mainly used to grind cement clinker in cement production process, and it also applies to grinding various ores and other grindable materials in industrial and mining enterprises such as metallurgical plant, chemical plant and power plant and so on Our company has more than 40year experience on the manufacture of cement ball mill, the quality of our product takes a Aug 02, 2013 In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do Often, the ball used in ball mills is oversize “just in case” Well, this safety factor can cost you much in recovery and/or mill liner wear and tearCalculate and Select Ball Mill Ball Size for Optimum GrindingJun 19, 2015 The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000 where: W = weight of charge C = distance of centre of gravity or charge from centre of mill in feet a = dynamic angle of repose of the charge N = mill speed in RPM HP = A x B x C x L Where A = factor for diameter Ball Mill Design/Power Calculation 911 Metallurgist
