A unit operation is a process that happens between streams . A unit operation can be as simple as a pump, or as complex as a distillation column. A unit operation can have 1 or more inlets, and 1 or more outlets. Each inlet or outlet that is used should be connected to a stream. Unit operations are external objects.

When the test ball mill is run in open circuit the design feed rate is tonnes/hour. Figure 4 compares the predicted size distributions from the open circuit ball mill with feed rates of, and tonnes/hour respectively. As might be expected, the larger the feed rate the coarser the grinding mill discharge product.
