On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

The reason for this variation in ball mill work index is because the ore at Mt. Milligan has an intrinsic exponent of in the 100 µm to 200 µm size range, not the exponent empirically measured by F. Bond. The work index increase between 100 µm and 76 µm is due to a porphyritic grain size that causes a spike in energy

Dry grinding is more often a continuous operation and is more advantageous for mass production. However, dry grinding tends to aggregate the powder particles because of the high surface energy of the particles. A major benefit of dry grinding is that higher densities can be achieved at lower temperatures.

The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...
