Disintegration of particles

The stress acting on particles is of high importance for many technical processes. As well as dispersion processes in two-phase systems (liquid/liquid or gas/Hquid), where the disintegration of particles is desirable, there are also a number of processes that may be adversely affected by particle disintegration. These include precipitation, agglomeration, crystalHsation processes, and also bio conversion with immobilised enzymes and the fermentation of sensitive microorganisms and animal and plant cells.

Atoms with the same value of Zbut different values of A are isotopes (Table 11.1). Many isotopes are stable but others are naturally or artificially radioactive, i.e. their atomic nuclei disintegrate, emitting particles or radiation. This changes the nuclear structure of the atom and often results in the production of a different element. 

The strong influence of the specific impeller power P/V and of the impeller type on the disintegration of floes can be seen from these curves, so that the effects of the operating conditions and the reactor type can be determined with satisfactory accuracy. The disintegration kinetics are complex, and show an exponential decrease in particle size with time. 

Sedimentary rocks have formed as a result of accumulation and compaction of mineral particles derived from pre-existing rocks, transported from their original places of occurrence and deposited in new environments. The essential ingredients for the formation of sedimentary rocks are (i) source materials, (ii) mechanical and chemical disintegration of these source materials, (iii) transportation of the released materials either in a clastic form...
