Optimal mill loading with LoadIQ |

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 efficiency. Conversely, with a new set of liners, the trajectory at high ...

The critical pH for passivation of steel balls during wet grinding of hematite ore was found to be With slurry pH below this critical value, corrosion played a significant role in the total wear of steel and the wear was temperature dependent. Above this critical value, corrosion was prevented and wear of steel, mainly due to abrasion, was independent of grinding temperature.

Both crushing and grinding require energy to reduce the ore size. However, in grinding operations we consume much more eneregy than crushing, up to 100 times ( thousands of kw compared to tens in crushing). Because as far as we go to finer size we need more force and collosions for further size reduction. In fact grinding is the most consume energy section for the whole processing plant, up to ...
