Coal comminution and sizing - ScienceDirect

01/01/2013  Double-roll crushers are able to crush more finely than single-roll crushers, because they are designed with teeth that mesh together rather than rotating past a smooth plate. They can reduce coal to as little as ¼ inch (0.6 cm) topsize, although they are more commonly operated close to 2 inches (5 cm). They have a higher capacity than comparable single-roll crushers. For example, a two-roll crusher

Dual roll crushers, how they function

Roll Crushers are compression type crushers, and were once widely used in mining. They have, within the last 10 or so years, fallen into dis-favor among mining and processing companies. The probable reason is because the large mines require very large crushed product output with minimal cost, makes the roll crusher uncompetitive. The roll crushers are not nearly as productive as cone crushers ...
