Single- and double- roll crushers are used for the initial reduction from run- of-mine to a nominal 6- to 8-inch size. A secondary crusher, often of the hammer-mill type, reduces it to less than 2 inches for shipping. In the central and eastern coal regions, all coal is similarly crushed and sized before shipping or processing.
