Because raw coal is still used in cement manufacturing, equipment that can grind coal onsite is necessary for most cement plants. As with the actual milling of cement, manufacturing equipment used to break down the coal requires mechanisms with airlock capabilities. These must be able to handle capacities from 10100 tons hourly.

Cement ball mill sizing method explanation 1 Introduction: The Bond 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.

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is that ...
