THE ENERGY-EFFICIENT TECHNOLOGY OF POWER-INTENSIVE GRINDING PROCESS

Abstract

Below - The results of laboratory studies of new energy efficient technologies grinding of raw materials. These technologies are the one of the most energy-intensive industries in the industry. These findings confirm the possibility of getting of groundbreaking of the technical and economic indicators in the implementation of the proposed innovative raw material grinding in ball mills. The last one is achieved by maintaining them in optimal trajectories of in-mill download depending on the constantly changing physical and mechanical properties (strength) of the crushed product. Inside the mill the most effective modes of grinding are quickly realized (impact, abrasion, crushing). Achieved a reduction in specific energy consumption depending on the strength of crushed material to 31,3 ÷ 43,5% while increasing productivity mills for raw materials of various classes fortress on 22,3 ÷ 57,3%. For Industrial test of offering technology was developed the variant of the automatic control of the fortress of the crushed material in the mill. The Books 5, Tables 3, Fig. 2.
