| 中文摘要: |
| 文章介绍了几种典型的饱磨故障案例，通过对磨机饱磨的原因分析，包括入磨原料水分问题、研磨体级配、磨内料球比和系统操作参数问题等，探讨了饱磨问题的解决措施，生产中要加强脱硫石膏原料管理，脱硫石膏不直接进磨头、适当提高一仓研磨体填充率、调节磨内隔仓板篦缝及出磨篦板大小、增加磨内流速，提高磨内研磨效率，增大磨内负压等等。 |
| 英文摘要: |
| The article introduces several typical cases of mill overfilling failures. By analyzing the causes of mill overfilling, including issues such as moisture content of the feed material, gradation of grinding media, material-to-ball ratio inside the mill, and system operational parameters, it discusses solutions to address the overfilling problem. In production, it is essential to strengthen the management of desulfurized gypsum raw materials by avoiding direct feeding into the mill head, appropriately increasing the filling rate of grinding media in the first chamber, adjusting the grate openings of the internal mill diaphragm and the size of the discharge grate, enhancing the material flow rate inside the mill to improve grinding efficiency, and increasing the negative pressure within the mill. |
