Roll Crusher - an overview ScienceDirect Topics

Rotary breakers, jaw crushers, roll crushers, or sizers are used to achieve particle size reduction. Crushing may also improve the cleanability of the coal by liberating impurities locked within composite particles (called middlings) containing both organic and inorganic matter.

Double Roll Crusher, 13mm Particle Size - Gilson Co.

Roll Crushers work well in preparing samples for further fine reduction using a pulverizer. Output size is controlled by adjusting the gap between the rollers using a hand lever. Feed hoppers offer high capacity, open easily for cleaning and maintenance access, and feature an electrical safety interlock that shuts down power to the unit when the hopper is opened.
