Calculate and Select Ball Mill Ball Size for Optimum Grinding
02/08/2013· The ball sizing formulas from the literature on ball diameter selection do not take into consideration such as the target P90 . Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of the single-sized balls in mm.d = the diameter of the largest chunks of ore in the mill feed in mm.Dipl.-Ing. Th. Fahrland, Dr.-Ing. K.-H. Zysk, Loesche GmbH,,for a ball mill system in closed-circuit operation with a high- efficiency, third-generation classifier would be between 0.75 and 0.98. The equivalent would be between 0.82 and 1.05 in a Loesche vertical roller mill system. These ranges may differ when different types of laser sizers are used.

Grinding machine - Wikipedia
A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting tool.Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.. Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high,,,,,,
