Gyratory Crusher

The capacity is similar to that of a jaw crusher with the same gape, and breadth 'B' equal to the perimeter of the gyratory crusher. Since all the coarse crushers have greater capacities than the devices for the finer ranges of size reduction, a gyratory crusher of sufficient size to crush the required size feed may have an excessive capacity.

Reduction Ratios in Crushing

The Limiting Reduction ratio - is the maximum feed size (known as F100) that can be put to the crusher and the maximum product size (p100) the crusher can produce. This ratio is a good starting point when choosing a crusher as it will give you an idea if the crusher will be able to handle the size of rocks you want to work with.

Roll Crusher

As mentioned earlier, the diameter to be adopted for the rolls is dependent upon the feed size and the nature of the material to be crushed. Since the reduction ratio for one pass of the material through a roll crusher is about 5–1, a higher reduction ratio may be obtained by putting the material through two crushers operating in series.

Assessing the energy efficiency of a jaw crusher

For a jaw crusher the reduction ratio (R) is defined with gape (G) as: (A.1) R = G L min [−] Therefore the close opening set ( L min ) for a jaw crusher can be written as: (A.1) L min = G R [ m ] Rose and English [4] determine the size for which 80% of the feed passed, by considering a large data set relating the maximum particle size to the ...
