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).

Sizers - HAZEMAG
In contrast to a Double Roll Crusher, the basic concept of the Mineral Sizer is the use of two rolls with smaller diameter shafts, because of the operation at a lower rotational speed by a direct high torque drive system. This design produces three major principles which all interact when breaking materials using sizer technology.
