I. Aerosol Size Range Particle size is often determined by the process that generated the particle. Combustion particles usually start out in the 0.01-0.05 Pm size range, but combine with each other (agglomerate) to form larger particles. Powder is broken down into smaller particles and released into the air; it is difficult to break down such

Size reduction of waste rubber is carried out in two steps. In the grinding process, the breakdown of particles is the primary objective so that the obtained crumb rubber can be fed into the subsequent processing stages. The successive stage is breaking of the chemical bonds (primarily sulfur bonds) in a process called devulcanization.

Rittinger, on the other hand, assumed that the energy required for size reduction is directly proportional, not to the change in length dimensions, but to the change in surface area. This leads to a value of -2 for n in eqn. (11.1, as area is proportional to length squared. If we put: K = K R f c And so;

Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is …
