Structural transformations taking place in the surface

During the comminution of powders of the ferrite BaFe12O19 in an attritor mechanical energy is expended in the disintegration of particles, formation of defects, and plastic deformation of the crystal lattice. The comminution of powders in a vibratory mill is accompanied by the formation of well-developed surface layers on particles, which are characterized by a high degree of defectiveness

Particle Size Reduction

Particles produced using a hammer mill will generally be spherical in shape with a surface that appears polished. The distribution of particle sizes will vary widely around the geometric mean such that there will be some large-sized and many small-sized particles. Particles produced tend to be uniform in size; that is, very little fine

Understanding The Dry Granulation Process

The original method of dry granulation employed a heavy duty tablet press to compact the dry powder. The compacting process in this case is known as slugging and the compacted material was therefore in the form of "slugs" - typically 25 mm in diameter and 10-15 mm thick. A hammer mill is ideal for breaking up the slugs to create granules.

In stirred-medium mills, the stirrers set the contents of the mixing chamber in motion, causing intensive collisions between the grinding medium and the ore particles and between the ore particles themselves. The grinding action is by attrition and abrasion, in which very fine particles are chipped from the surfaces of larger particles, rather than impact breakage.
