What you should know to select medium-fineness grinding equipment

If you need to reduce particles to between 100 mesh and 1 inch, you'll find information in this article to help you select grinding equipment. Sections discuss the many types of equipment that can grind particles to medium fineness, as well as factors to consider when selecting equipment.

Several theoretical laws apply to solving size reduction problems. Kick's law states that the work for a given reduction ratio is the same, irrespective of the starting size. Rittingler's law states that work is proportional to the size produced. And Bond's law states that work is inversely proportional to the square of the particle diameter. These commonly quoted statements seem obvious and have proven true for some applications, but they don't produce a formula you can apply to all size reduction problems.
