The grinding process of the ball mill is an essential operation in metallurgical concentration plants. Generally, the model of the process is established as a multivariable system characterized with strong coupling and time delay. In previous research, a two-input-two-output model was applied to describe the system, in which some key indicators of the process were ignored. To this end, a three

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The

MILL FEED CONTROL. Smooth operation of a milling circuit is difficult to achieve due to: • The varying nature of the feed material (size, ore hardness, etc.). • The unfavorable dynamics between feeders and the weightometer. These dynamics degrade the performance of PID controllers, making feed optimisation more challenging.

As each ball rolls through the counting chute, an electro-mechanical limit switch is activated, signalling the counter. Each count is added to the last, allowing a continual increasing total count of balls to enter the mill over a set time period. The total ball count can be monitored on the control panel at any time. A controller is used to

A process control agent (PCA) is usually used in the process of mechanical alloying to avoid cold welding and bonding between the powder particles and the balls and the agglomeration of powder during milling, which is also noticeable for some alloy systems in the solid–liquid reaction ball milling process (Chen and Chen, 2006). Thus, an investigation into the effect of PCAs on solid–liquid
