Grinding Mills and Their Types

Very fine grinding mills. The following are the mills used for very fine grinding. Hammer mills. Hammer mills are high speed mills operating at speeds of between 2000 rpm and 6000 rpm. A set of 'hammers' rotate about a central axis in a vertical or horizontal plane. The hammers are either be fixed or are swinging freely.

Particle Size Reduction and Enlargement

Size reduction takes place by a shearing action between the edges of the grooves on the two grinding stones. This equipment has been used for the grinding of grain, pigments for paints, pharmaceuticals, cosmetics, and printer's ink, although it is now used only where the quantity of material is very small.

ATTRITORS AND BALL MILLS HOW THEY WORK

well on hard, brittle materials. They are not as suitable for grinding elastic, ductile or fibrous materials, or for fine grinding in general. Ball mills can blend and grind at the same time, yielding a fine, intimate mixture. Conventional ball mills are usually limited to a particle size of 1µ after one hour of grinding

Understanding the Difference Between Crushing & Grinding …

Types of Grinding Equipment. ... Common examples include ball mills, rod mills, and attrition mills. Ball Mills: Fine powders are produced when these kinds of machines crush materials using steel balls designed for that purpose. As it rotates, the drum causes these balls to fall onto the material, where they then grind it through impact and ...

Size Reduction

Shear or attrition forces are applied in fine pulverization, when the size of the products can reach the micrometer range. Sometimes the term "ultrafine grinding" is associated with processes in which the submicron range of particles is attained. Finally, cutting gives a definite particle size and may even produce a definite shape.
