Multiple Choice Questions on Mechanical Operations

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.
