## Bond equation of cement ball mill sizing CHAENG

The method is used to size a cement ball mill. Efficiency correction factors are applied with the Bond equation. The method is valid both for clinker grinding and for raw materials grinding. This method only gives a rough and initial idea for sizing a cement ball mill.

The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio "length to diameter" and this ratio most frequently varies from 0.5 to 3.5....
