针对安徽某选矿厂圆锥破碎机主润滑油污染造成的一系列问题，在分析原因的基础上
介绍了改造方案与实施情况。通过优化正压防尘系统、选用离线过滤机、加强检修现场管理和日常
维护管理、正压风机和离线过滤机设置报警系统，可以降低圆锥破碎机非计划停机时间 40 h/a，增产
4.68万t/a；节约壳牌150#
润滑油28.44万元/a、主润滑滤芯及主润滑油泵等费用108.2万元/a；圆锥破碎
机的良好运行状态使工作压力由4.0 MPa提高到4.4 MPa，合格粒度产品占比增大，减轻循环负荷，破
碎机作业率下降 3.4个百分点，降本增效效果显著；设备故障率的下降、非计划检修时间的缩短减轻
了工人的劳动强度。现场圆锥破碎机主润滑油防污染措施的落实，使得扩能、增产、提质、增效效果
显著，具有推广应用价值。
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.
