Abstract.

The article presents findings on correlative dependence between various external factors and parameters of general-purpose conveyor which prove that among the total number of factors the most important one which significantly impacts on the efficiency of the conveyor operation is a size of the bulk cargo as it reduces life of supporting elements, increases tractive resistance of the belt on the roller carriage and increases costs of the conveyor restoration.

It is shown that with increasing angle of the conveyor inclination the correlative dependence decreases (К_в = 0,3–0,5 ). To create an adequate model of such interdependence between parameters and factors absolute (operation complexity and safety of bulk cargoes transporting) and relative (power consumption, reliability and costs) criteria ere determined. Regularities of their changes depending on conditions of conveyor operation and effective area for the conveyor usage are presented.

Keywords:

conveyor, belt, criterion, bulk cargo, cargo size, traction body, inclination angel, roller carriage, roller, parameter, conditions of operation, regularities.
