Assumptions of Probabilistic Model of Grains Density Distribution in Jig Bed Layers

Abstract

Significant limits of grain disperion in layers of the jig bed and the consequences of these limits are shown in the presented paper.They are
the results of large grains dispersion in relatively small range of jig bed density layers. These limits are omitted or incorrectly presented in the
descriptions of the phenomena occuring in the jig operation in most of existing papers. Correct conditions and assumptions of probabilistic
model of these phenomena are presented. The construction of this probabilistic model does not have any restrictions for proper creation of the
density layers of jig bed and amount of mass distributed in these layers. The experimental validation of this model in the laboratory conditions
is possible in particular situation. Additionally this model explains some errors existing in gravitional benefication theory.
