The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.
The reduction ratio—that is, the ratio between the " inch size " of the largest lump entering the machine and that of the largest piece leaving it—is usually between 4 and 6 to 1 for either machine.
