    The Differences Between Double Roll Crushers and

    The kinetic energy stored in the flywheels combined with the higher roll speeds powers the crusher through peak crushing moments. The DDC-Sizer does not utilize flywheels, and the rolls rotate at approximately one-third of the speed of the V-belt driven crusher. Therefore, due to the torque required to perform the crushing action, greater motor horsepower is required. Roll Speeds and Feeding

    Roll Crusher an overview ScienceDirect Topics

    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 with 24-inch
