进口煤焦破碎机的国产化改造

LOCALIZATION REFORM OF IMPORT COKE CRUSHER

进口煤焦破碎机具有产量高、粉化率低等优点,但由于国内制造技术和材料技术的原因,导致设备运行故障率频繁、运行费用高。文章深入分析了导致问题的原因,并采取了改变破碎方式、进行可修复性和互换性设计,效果显著,齿辊平均破碎焦量由原来不足5 000 t,提高到接近20 000 t,其他各项指标均有较大的改善,并取得了明显的经济效益。

Imitation import coke crusher has advantages like high output, low pulverization rate, but due to domestic manufacturing and materials technology, failure rate of equipment operation is so much, the operation cost is high. This paper deep analyses the cause of problems, it has significant effect by changing crushing way and taking repairablity and Compatibility design, original average crushing coke quantity of tooth roll is not enough 5,000 t, but now about 20,000t, other targets also have greatly improved, achieving obvious economic benefits.
