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.
>Mathematical Modelling of Comminution Processes ...
Simplifying the resulting equation the mathematical model for ball mills may be written as (11.36) P = D • R − 1 • (D • R − 1 + I − A) − 1 • F. This perfect mixing model has been successfully used to simulate ball mill and rod mill operations. It can be used for steady state and dynamic simulations of milling processes.
