近几年来,重介选煤技术在我国选煤系统得到迅速的推广和发展,重介选煤技术因具有系统简单、分选效率高等优点,深受青睐,但在生产过程中,管路磨损严重,为此,我们选用了耐磨管路,然而实际使用过程中发现弯头部分和管路转弯部分仍然磨损严重,例如,我厂三产品重介旋流器系统矸石集? In recent years, heavy medium coal preparation technology has been rapidly popularized and developed in China’s coal preparation system. Heavy medium coal preparation technology is favored due to its advantages of simple system and high separation efficiency. However, in the production process, the pipeline wear Serious, therefore, we use the wear-resistant pipe, but the actual use of the process found that the elbow part of the pipe and turn some still serious wear and tear, for example, I plant three products HM cyclone system set?
