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.
Highlights
For modern concentrating machines is an evidence the trend to expansion of functional possibilities due to rising of operational loads under metal intensity decrement, enhancing productivity and the reduction of the refinement time, improvement of the accuracy, efficiency and reliability [1]
The investigations, which took place in the Mining college of NUST MISIS (Moscow), had proved the possibility to estimate the evaluation of an equipment with a help of an versatility indicator, calculated on the base of aggregation of the simple measurements, characterizing the resources spends on achieving a unit of the final result of work [2]
The complex indexes, calculated on the basis of aggregation of simple measurements, are the lows of least action, which was generated by Maupertuis, Euler, Lagrange, Hamilton and other scientists [3] and which were used by modern scientist as criteria of
Summary
For modern concentrating machines is an evidence the trend to expansion of functional possibilities due to rising of operational loads under metal intensity decrement, enhancing productivity and the reduction of the refinement time, improvement of the accuracy, efficiency and reliability [1]. The investigations, which took place in the Mining college of NUST MISIS (Moscow), had proved the possibility to estimate the evaluation of an equipment with a help of an versatility indicator, calculated on the base of aggregation of the simple measurements, characterizing the resources spends on achieving a unit of the final result of work [2]. The complex indexes, calculated on the basis of aggregation of simple measurements, are the lows of least action , which was generated by Maupertuis, Euler, Lagrange, Hamilton and other scientists [3] and which were used by modern scientist as criteria of. Criteria of specific actions assesses the degree of sophistication of analyzed systems, elucidate the parameters under which the system is close to optimal [5]
