Using Micronization to Reduce API Particle Size ,, 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 particl Jet millingSize reduction, The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclon The cyclones send correct-size material on to flotation and direct oversize material back to the ball mill for further grindingBall milling, A device used to reduce the particle size of materials, bodies or glaz A ball mill is simply a container that is filled with pebbles (either of porcelain or stones eg Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to ,.
