The product from an open-circuit ball mill therefore exhibits a wide range of particle size and overgrinding of at least some of the charge becomes a problem. Closed-circuit grinding in mills providing low residence time for the particles is almost always used in the last stages to overcome this.

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.
