• process of separation
• slotted sieve
• granulated matter

The process of sieve separation might be treated as some kind of random experience, in which the fact that a particle (of a size smaller than the sieve separation size) will pass through its slot in a given place, is to be determined by probability. It could be alternatively said that during classic sieve separation, there are areas at the sieve for which the probability of separation is higher and, in consequence, areas with the lower probability measure. If we assume that the separation process runs stable in regard of the external conditions, then we could say that values of the mentioned probabilities in given areas are not varying significantly. Relatively small deviations from average values are called fluctuations, and are considered to be perfectly normal. However, when the external conditions (e.g. a change in the granulometric composition of a mechanically fed material, a change in the sieve inclination, etc.) are changing, then the configuration of the above mentioned probabilities should also change.
