The fractional filling of the mill with balls only in the mill is given as JB (B as a subscript). In the case of a ball mill, the same definition applies. However, the definition gets a bit misleading when a slurry pool forms in the mill and the volume of the pulp exceeds the volume of the voids in the grinding media.

In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.

This means that in operation, the pebble crusher remains in an intermittent operating state. The size of the ball mill is slightly undersized, which could explain why the circuit is unable to reach the designed product size (115 µm). Furthermore, the operating capacity of the ball mill has reached 90% capacity, running at near full load.
