The grinding curve is the product size as a function of feedrate, for a fixed feed size. It is proposed that for each new milling condition, in this case a change in the percentage of ball scats in a mill, the peak in the grinding curve must be sought, and that must be used as the comparative test condition.[...]

Dec 18, 2013· Similarly, in ball mills, it is known that grinding finer than approximately 40 μm will result in overgrinding of fines as well as high media consumption. However, it must be noted that the product size to which a mill can efficiently grind depends on the feed material, the F80, and media type and size.[...]
