Specification framework for robust control of a run
The ROM milling circuit model with its uncertainty and performance weights is then cast into a general synthesis and analysis framework. Abstract It is difficult in run-of-mine (ROM) milling circuits to control the particle size of the product and other important variables because the ore fed to the mill also acts as the main grinding medium.
