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.

3.2 Shaft speed. The 2nd key design and operational aspect for a hammer mill is the rotation speed. As the milling principle is based on the energy of the impact, the higher the speed, the finer the product can be expected as the particles will hit the hammer at high speed, but also be sent against each other or against the screen at high speed.

Feb 25, 2016 The Jeffrey Heavy Duty Reversible Hammer Crusher is designed especially for reducing bituminous coal down to a product of 85% minus 1/8″, at large capacities, for coking purposes. These machines are also adaptable to the reduction of abrasive materials since they are symmetrical about the vertical center line and when one corner of the hammers become worn, it is only necessary to reverse the direction of the rotor in order to use the opposite unused faces of the hammers.

Breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory. High reduction ratios of between 20:1 and 40:1 can be achieved with hammer type impact crushers. Only low reduction ratios of about 2:1 can be achieved with kinetic energy type impact crushers.
