That is to say, the work done, in crushing a given weight of ore from any one stage to the next, would, from this reasoning, be proportional to the number of particles at the first of these two stages. If this were actually the case, the law deduced would give, with the finer sizes, extremely large work values, even larger than Rittinger's ...

In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to …

Both crushing and grinding refer to particle size reduction; the principal difference between these two designations is that grinding implies smaller mean particle sizes. The ability of rocks or minerals to withstand fragmentation depends on the hardness and structure of the material and the manner of fracturing.

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test …

New Surface Formed by Grinding When a uniform particle is crushed, after the first crushing the size of the particles produced will vary a great deal from relatively coarse to fine and even to dust. As the grinding continues, the coarser particles will be further reduced but there will be less change in the size of the fine particles.
