Purpose: Research and development of new high-performance equipment for technological processes of crushing and sorting of hard rock Demidov deposit of granites. Research Methods: modern methods of mathematical modeling of physical processes and experimental researches conducted by using modern vibratory and tensometric. Theoretical and practical results: the use is justified to control hydraulic vibration and shock-and-vibration units for mining and other kinds of machines valved pulsators with two cascades; developed a classification and structural determinants of the matrix of possible embodiments of the schematic and design of hydraulic drives; proposed mathematical calculation methods and developed methodology, algorithms and recommendations for project engineering design of hydraulic drive model, technical solutions are implemented in the study of hydraulic drives are recognized invention (technical solutions protected by more than 100 copyright certificates and patents). Scientific novelty: a complete and developed a simplified mathematical model, justified the selection criteria and characteristics of the basic parameters of the hydraulic drive workflow model of shock-vibration unit, controlled by valved pulsator indirect action with two cascades. Scope: the technique and recommendations provided by firm "The granite quarry" to calculate and justify the selection of parameters for the new attack nodes, hydraulic hammers, vibrating conveyors, screens, crushers, vibratory mills and other vibratory machines.
