  • The importance of the size of the beads to be selected

    The bead size is the most important factor for milling practices. Large beads, bigger than mm, are adequate for grinding micronsize particles into submicronsize ones. Small beads, mm or finer, are applied to grinding or dispersing submicron or nanometersize particles. For dispersing, a large impact is not necessarily required, and ...

  • What Are the Advantages of Wet Grinding vs. Dry Grinding?

    Sizes smaller than 1 micron in diameter are referred to as the nanometer level. One micron is equal to 1,000 nanometers. Typically, nano sized particles range from 200500nm. The process of achieving particles this small is sometimes called nanonization. In general, dry grinding can reduce particles to singledigit micron sizes.
