In separating lines at different stages of the technological process is carried out fractionation of the bulk material. These different quality streams subsequently processed on the working bodies or machines that are more suited for a specific faction. Fractionation can increase productivity, reduce costs, reduce the amount of material being processed through the working bodies of the passes. Criteria for selection of the working body for fractionation and its place in the production line depends on many factors and insufficiently developed. The aim of this work is to determine the criteria for evaluating the effectiveness of the working body for the fractionation of the raw material on the basis of a possible increase productivity throughout the production line. The curves obtained by calculation, allow us to estimate the total increase in line speed. Obtained dependence can be used for calculations of separation processes of granular mixtures in the production of building materials, food industry, powder metallurgy, pharmaceutical and other.
