Capacity: The capacity can be calculated for every station in a business process. It is always m / processing time with m being the number of resources ( workers) being devoted to the station. If, for example, one worker needs 40 seconds to put together a sandwich, the capacity of this station is 1/40 per second or 1,5 sandwiches per minute.

The capacity not only determines the mill equipment size, but also dictates how to operate the mill, whether continuous or batch operation is required, and whether the process can be performed inhouse or if a tolling service is a better option. The required product size is an important grinding cost factor, especially for finesize grinding.
