Disturbance Rejection
for Ball Mill Grinding
Circuits
11.1 Introduction
Ball mill grinding circuits are amongst the most important operation units in min-
eral processing plants. Grinding processes hold almost 50% of the total expenditure
of concentrator plant. Moreover, the product particle size influences the recovery
rate of valuable minerals as well as the volume of tailing discharge in the subsequent
processes. Generally speaking, the aim of grinding processes is to maintain stable and
effective control of the product particle size and the circulating load. However, un-
desirable characteristics, ...
