METHOD OF SELECTION OF TECHNOLOGICAL SCHEME FOR PROCESSING MINERAL RAW MATERIAL

摘要

FIELD: concentration of raw mineral materials; construction and reconstruction of concentrating mills. SUBSTANCE: method consists in determination of grinding device productivity and degree of opening by each base technological scheme at preset technological parameters pertaining to grinding and opening of ground material and operational parameters of grinding and separating devices. Besides that, parameters characterizing negative acceleration of grinding and opening of mineral raw material are determined. Then, productivity of grinding device is determined according to size and degree of opening by each base technological scheme at preset technological parameters of grinding and operating of ground material and operational parameters of grinding and separating devices are determined from mathematical relationships. EFFECT: enhanced efficiency; increased productivity due to optimal selection of technological scheme of processing. 1 dwg
