Kiriya R. Optimization of the Parameters of Passive Shifting Knots of Belt Conveyers of Mining Enterprises

Processes of co-operation of bulk load with the elements of shifting knots of belt conveyers working in the conditions of mountain enterprises. Increase of efficiency of work of passive shifting knots of belt conveyers by optimization of their parameters. The methods of mechanics of solid substance, kinetic methods of statistical mechanics, methods of optimization are research methods. Critical speed of stream of bulk load, at which it passes from one structural-mechanical state to other, is first found. The values of coefficients of losses of mechanical energy of stream of bulk load are obtained in theory and confirmed experimentally. The method of calculation and optimization of parameters of passive shifting knots of belt conveyers, which is inculcated in planning organizations, is developed, that allowed to decrease the number of refusals of shifting knots more than in two times and get an economic effect of 210 thousand rubles in the prices of 1991. Mining, metallurgical and building industriesare the sphere of the use.
