Throughput optimisation in milling circuits

Each milling circuit is unique, and as such the goals and most optimal control strategy might differ for individual cases. Process IQ is an expert in implementing control systems for SAG and Ball milling circuits, making use of advanced stabilisation and optimisation strategies developed by Mintek.

Total primary milling cost reduction by improved liner design Total primary milling cost reduction by improved liner design

Total primary milling cost reduction by improved liner design

Total milling cost is composed of energy, liner and grinding media cost. In primary high ball load milling, the grinding media plays the biggest role in total milling cost. This cost can be drastically reduced by improving the impact condition inside the mill.

Mineral resources all over the world are often heterogeneous and have variable ore properties and ore grade. As a result the ore processed in concentrating plants varies over the life of mines. Consequently the circuits often suffer from bottlenecks typically at the stages of crushing, semiautogeneous (SAG) and ball milling. Bottlenecks may be remedied with equipment retrofits, however ...

conventional milling plants considered and actually retrofitted their plants with AG/SAG mills. Historically, the most widely used method to establish the AG/SAG grinding requirements for processing an ore from a deposit was to obtain bulk samples, each weighing 10 to 100 tons, and grind them in a test grinding mill having a minimum diameter of

 · Quite often Autogenous (AG), SemiAutogenous Grinding (SAG) and Ball Mills are present in mining and mineral processing plants. The grinding process of these tumbling mills is produced by a range of mechanisms including highspeed impact, abrasion, chipping and nipping of small particles between large ones due to the rotation of the mill upon its horizontal axis.
