2017-10-23  A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill

1. Wear and tear in wet crushing is more than that in dry crushing of materials. 2. 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. 3. Size enlargement (opposite of size reduction) is not a mechanical operation. 4.
