Ball Mill Design Power Calculation Linkedin

AG SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill Because of the range of mill sizes available AG SAG milling can often be accomplished with fewer lines than in a conventional rod mill ball mill circuit A diagram of types of AG SAG.A ball mill can safely operate at 90 of its motor rated power so choose a motor size like this Motor size as kW = Power 0 90 You will not get a circulating load prediction from a Bond calculation The assumption is that your secondary circuit is efficient whatever that might mean.The grinding product size P in a Bond ball mill which is given by the aperture size which passes 80 of the grinding product as a function of the aperture size of the test screen Pk can be expressed by the formula P= P k K 2.
