The size characteristics of the feed are important consid- erations. The coarser the feed, the larger the number of crushing stages and degree of compaction the feed has to undergo before it is discharged. It is commonly observed that the degree of compaction of the product decreases with increasing coarseness of the feed.

The crushing action in gyratory crushers is regarded as rings or 'helics' (spirals) of feed down through the crusher of which a single section may be regarded as similar to the jaw crusher. Therefore, computations leading to the performance of gyratory crushers may be considered very similar to jaw crushers.
