A raw material grinding circuit was modeled using plant data. Samples were collected from around the circuit and, following a crash stop, from inside the mill. The size distributions of the samples were determined down to a few microns. Using the data from inside the mill a modeling approach, based on perfect mixing, was developed.

Grinding circuit Optimization - Grinding & Classification ...
Ball Mill Circuit Classification System Efficiency As described above, "fines" may be defined as any material smaller than a specified product size, and "coarse" as any material that is larger. The target 80 percent passing size of the grinding circuit product is a convenient reference point, as it is often used to express the grind size objective.

MILLING CONTROL & OPTIMISATION - Mintek
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.

Ball Mill Operation -Grinding Circuit Startup & Shutdown ...
The grinding circuit operator must ensure that the ball mill runs properly loaded and gives the correct ore grind. A major practical indication of mill loading is the sound made by the mill. A properly loaded mill will have a deep rhythmic roar, while an under loaded mill will have a metallic rattling type noise and an overloaded mill will be quite silent.
