Jan 16, 2013· Micronization is most often used to describe processes that reduce particle size by using fluid energy, such as a jet mill, rather than by mechanical means. Mechanical particle-size reduction using a bead mill, however, can also be used to obtain micrometer- and nanometer-sized particles.
The minimum size of grinding balls should be selected with caution since there will be a tendency for such balls to float out of the mill in a dense pulp (this is minimised by the use of a grate discharge mill). Also the smaller the media the quicker it will reach its reject size.
A small media mill is an enclosed vessel filled with thousands of small spheres or beads (the grinding media) that are activated by a high speed agitator shaft, creating shearing and impacting forces.
