  • PARTICLE SIZE REDUCTION TECHNIQUESSlideShare

    Mar 25, 2016 · BALL MILL Principle The ball mill works on the impact between the rapidly moving ball and the powder material, both enclosed in a hollow cylinder. Thus, in the ball mill, impact or attrition or both are responsible for the size reduction. Fig Ball mill 13 14. Working The drug is filled into cylinder 60 of the volume. A gold grain, for example, is still organized according to the cubic face-centered lattice structure, even after rolling. The more slip planes available in a grain and the greater degree that the atoms shift on these planes, the more the grain changes from its original shape.

  • Hammer MillsSize Reduction Equipment for Bulk Materials

    Particle sizes are determined by the friability of the material and the size of bedscreen perforations which range from 1/32 to 3 inch (0.8 to 76 mm). The shaft assembly, which consists of a primary shaft, multiple discs and six hammer mounting bars, are driven at 1,800 to 3,600 RPM by a high horsepower motor. The industrial pin mill (also known as a universal mill, turbo mill, and impact mill) is a one pass grinding equipment ideal for achieving the micronization of bulk materials and powdered products. Common applications involve the fine grinding of sugar, salt, sodium bicarb, etc. The average achievable particle size range of the pin mill is around a d50 of 80 microns.
