Cutting Tool Applications, Chapter 16: Grinding Wheels and Operations

For example, a 60-grit-sized grain will pass through a screen with 55 openings per inch, but it will not pass through a screen size of 65. A low grain size number indicates large grit, and a high number indicates a small grain. Grain sizes are broadly defined as coarse (6 to 24), medium (30 to 60), fine (70 to 180), and very fine (220 to 1,000.)

CPE: Lesson 13. Principle of Size Reduction

In general, compression is used for the coarse reduction of hard solids (to yields relatively few fines), impact gives coarse, medium or fine products, attrition gives very fine products from soft, non-abrasive materials and cutting produces a product of a definite particle size and sometimes a definite shape, with few or no fines.
