Abstract

The article presents the results of the investigations of evaluation of the effectiveness of implementation of the equalized functionality mineral-processing equipment, using criteria for the specific action, calculated based on the simple indexes aggregation, which describes resource, spending on achievement the end result unit of the functional event (multi-criteria estimation). As a major specific action criterion for the estimation of milling equipment we used the criterion, which takes into account expenditure of energy and time. The need to generate more production-friendly constructions became a reason for creation of the recommendations for further improvement of the mineral-processing equipment. These recommendations based on selection of the milling process variables, which has the greatest impact on the qualitative and quantitative indicators of mineral processing, and on analysis of possible changes of chosen parameters to decrease in the specific actions. In conformity with the practical implementation of these development principles, have been developed the new methods of milling and construction arrangement of the mills, based on the implementation of the specific action criteria, which ensure the positive effect, resulting from the decrease in unit costs during the manufacturing of saleable products from the mineral row materials.
