АННОТАЦИЯ:

Current issues of energy saving in cement production, using technological milling complex, which includes a press roller crusher and ball mill, discussed in the article. Optimized milling conditions of previously ground material through the installation of energy-exchange blade devices (EBD) in amill drum have been proposed. It was found that the level of charge by grinding media in the first chamber periodically varies according to the rotation angle of the mill drum equipped with EBD. There is a "scooping" of the grinding media with a grinding material in the zone of active influence of EBD along, lifting them to a height and enforcing them a cross-longitudinal movement. All that is different from being created in the ball mills without EBD. The additional work is performed, which consumes engine power. Method of calculating anadditional power consumption of the mill drive equipped with EBD was proposed; additional power expended to create cross-longitudinal motion of the grinding mediain the first and second chambers initsareas of activein fluence of EBD. The comparative analysis of the results obtainedby experiment and calculation son the proposed equationss howed high convergenceresults. The analytical dependencies maybe of interest for both Russian and foreign organizations operating in the design and manufacture of cement equipment, as well as for cement manufacturers.
