Introduction to Mineral Processing or Beneficiation

Jan 12, 2021AG mills employ ore as the grinding media. However, one the challenges with AG mills is that properties, such as hardness and abrasiveness, of the ore can vary, resulting in inconsistent grinding behaviour. The addition of steel grinding balls rectifies this situation.the efficiency of the grinding process significantly reduced.

Optimal mill loading with LoadIQ

Maximum efficiency. Liner wear is directly correlated to the ore trajectory in a grinding mill for a given RPM. As the liners wear, the ability to strike the toe at higher volumetric fills may not be possible. In cases where this is true, the volumetric load will automatically be decreased until the toe is impacted, thus restoring maximum
