The article describes research data on evaluation of the single-function mineral processing equipment efficiency by the specific performance criteria calculated from aggregation of simple indexes of resource consumption per unit functional event (J – criterion point). In the capacity of the governing criterion of specific performance in evaluation of processing equipment efficiency, the mechanical energy–time input is used. The feature of the J-criterion evaluation of equipment is feasibility of new designs capable of highest-level implementation of the specific task of a process flowchart in the given conditions. The required production effectiveness of designs calls for development of principles for further improvement of mineral processing equipment based on selecting such milling parameters that have the major effect on the qualitative and quantitative indices of mineral dressing, as well as on the analysis of change of the selected parameters with a view to varying the indices toward reduction in the specific performance. Based on the implementation of the improvement principles, new milling methods and structural arrangements of milling machines are developed using the specific performance criteria. These criteria allow positive effect to be reached owing to decrease in cost per output in manufacturing of various marketable products from mineral raw materials. The new-designed structural arrangements of milling machines are protected by author’s certificates and patents. Some of them have already been introduced into production.
