Abstract:There are 10 material feeding hoppers in the material preparation workshop of Guixi Smelter , including 6 in one system and 4 in the second system. According to statistics, the workshop transported more than 2 million tons of copper concentrate raw materials and other auxiliary materials such as quartz sand to the next process throughout the whole year. As the first pass of belt conveying system,whether the feeding is stable or not directly affects the conveying efficiency, and is particularly important for the pre-drying production conveying efficiency, energy management and control, and various process index parameters. Combining with the practice of independent project of the first system feeding hopper in the workshop, precise measures are taken at the source of conveying, so as to stabilize feeding, further improve the efficiency of feeding hopper, and escort the smooth production.
