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

2. Wear and tear in wet crushing is more than that in dry crushing of materials. 3. Size enlargement (opposite of size reduction) is not a mechanical operation. 4. A ''dust catcher'' is simply an enlargement in a pipeline which permits the solids to settle down due to reduction in velocity of the dust laden gas. Correct.
