Wu Huanxun and other reform introduced the practice of high-grade ore crushing grinding Yunfu pyrite, 1996 Yunfu pyrite pyrite to -3 mm production technology to transform high-grade ore line reached 80 million t / a of -3 mm pyrite production Scale; After the renovation of the fine crushing equipment at the end of 2007, the capacity of the rich ore has exceeded 1.5 million t/a of the original design, reaching 2.4 million t/a, and the capacity of the equipment is significantly improved. In 2009, the capacity of the rich ore line was more than sufficient. Increasing the grinding system, the slurry is transported to the lean line flotation, and the first implementation of the -3 mm pyrite mine converts the sulfur-rich concentrate with higher economic value. Meng Fanyi analyzed and studied the problem of silt clogging and low crushing efficiency caused by the increase of mud content and water content in Yuntaishan pyrite ore, and solved the problem of easy clogging of vibrating screen by using self-designed double-loop conveying belt. The technical and economic comparison results before and after the transformation show that the benefits of the crushing and grinding section after the transformation can be increased by 892,000 yuan per year before the transformation. Anhui Xinzhongyuan Chemical Technology Co., Ltd. has studied the crushing process and equipment selection of a low-grade pyrite mine with low comprehensive utilization rate, serious pollution and poor economic benefits. Segment grinding - 1 coarse 2 fine 1 sweeping flotation - the process of flotation tailings magnetic separation, finally obtained a sulfur concentrate with a sulfur grade of 46% and an iron concentrate with an iron grade of 60%, achieving this low Comprehensive and efficient use of grade pyrite resources.

In recent years, the research work of pyrite ore dressing workers on crushing and grinding and grinding classification is relatively small, mainly for the process transformation and the problems of unreasonable processes and low production efficiency in production. Work on equipment selection.
