    Model Predictive Control for SAG Milling in Minerals

    Model Predictive Control for SAG Milling in Minerals Processing Steven J. McGarel, Rockwell Automation Introduction SAG and ball mills are generally accepted as the largest power consumers in a mining and mineral processing operation and can be 80% of total electrical energy consumed at a specific power consumption of around 20kWh/ton.

  • Sino Grinding Mineral Processing

    Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semiautogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process. The mix of media and ore rises and falls in the mill like clothes in a

  • SAG Mill Liners Breakage Grinding Classification

    I assume you are referring to a ball mill, since cyclone discharge recycle normally goes back to ball mill feed. I am less versed in ball mill grinding. Ball mills break rock by compression fracture, while SAG mills predominantly break by shear. Some compression fracture does occur, but, it is not the major comminution mechanism.

  • Ball mill

    A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
