Analysis of the causes of uneven fineness of Raymond mill

[xuanxuan geng]

As a modern milling equipment, Raymond mill itself will encounter various problems in the production process, such as performance degradation and wear of wearing parts. Recently, some customers have reported that the fineness of the milling of the Raymond mill is uneven. Then, Shanghai SBM Heavy Industry made an analysis, the specific contents are as follows:
1. Hardness of raw materials
For different materials, the hardness is different. The hardness directly affects the grinding difficulty and fineness of the Raymond mill, so the harder the material, the greater the degree of grinding. In the process of using Raymond mill, reasonable ingredients should be used to ensure that the size of the material is uniform and the fineness of the mill.
2. Opening height and size of classifier
During the installation of the Raymond mill, if the size of the opening of the classifier is not adjusted properly, it will affect the grinding operation and the fineness of the grinding. Therefore, in the installation and production process of Raymond mill, it is necessary to pay attention to check the opening size and height setting of the classifier.
3. Damage of the impeller blade of the analyzer
During the grinding of materials by Raymond Mill, if the blade of the analyzer is seriously worn, the fineness of the material after grinding will become coarse, which will affect the quality of the grinding. At the same time, if the blade of the analysis machine is seriously worn, it will affect the overall performance of the equipment, so as to shorten the use time of the equipment.
4. Wear of grinding roller and grinding ring
In the production process of Raymond mill, the grinding roller and the grinding ring are in direct contact with the material. In the long-term grinding process, different degrees of wear will occur. Once the grinding roller and the grinding ring are seriously worn, it will affect the fineness of the equipment degree.
