conversion and optimisation of open circuit ball mill to close circuit

PDF Dynamic matrix control of milling circuits

Grinding circuits are multivariable in nature with large interactions and time delays and demand that they be operated at constraints for profitable operation. It is recommended that on-line optimization of milling circuits be investigated for maximum benefit from the control algorithm.

This article explains what open circuit voltage is

Open Circuit Voltage Represents a Voltage Source's Full Voltage. Because it doesn't drop any voltage across a load, as what would happen when it is connected to a load, a voltage source's open circuit voltage represents its full voltage value, since the voltage doesn't share any of its voltage with
