Research and Application of Main Lubricating Oil Pollution Control of Cone Crusher in a Concentrator
In view of a series of problems caused by the main lubricating oil pollution of cone crusher in a concentrator of Anhui Province,the transformation scheme and implementation are introduced on the basis of analyzing the causes.Optimizing the positive pressure dustproof system,selecting the off-line fil-ter,strengthening the maintenance site management and daily maintenance management,and setting the alarm system for the positive pressure fan and the off-line filter can reduce the unplanned shutdown time of the cone crusher by 40 h/a,increase the production by 46 800 t/a,save shell 150#lubricating oil 284 400 yuan/a,the main lubricating filter element and the main lubricating oil pump and other costs 1082 000 yuan/a.The good operation state of the cone crusher increases the working pressure from 4.0 MPa to 4.4 MPa,in-creases the proportion of qualified particle size product,reduces the circulating load,and reduces the opera-tion rate of the crusher by 3.4 percentage points.The effect of cost decreasing and benefit increasing is re-markable.The decrease of equipment failure rate and the shortening of unplanned maintenance time reduce the labor intensity of workers.The implementation of the anti-fouling measures for the main lubricating oil of the cone crusher on site has a significant effect on capacity expansion,production increase,quality improve-ment and efficiency increase,and has the value of popularization and application.
