As a commonly used grinding equipment in industrial production, Raymond mill is favored for its high efficiency and stable working performance. However, some users reported that its working efficiency has gradually decreased and is not as efficient as before. There are many reasons for this situation, but it can be mainly attributed to two major factors: process and equipment. In order to deeply understand the reasons for the decline in the working efficiency of Raymond mill, we can analyze it from the following aspects:

1. The core component of Raymond mill, the grinding roller part, will gradually wear after long-term use, and the grinding teeth will become blunt, resulting in a weakened grinding effect. In addition, if there are problems in the installation process of the grinding roller, such as improper arrangement of the slope and tooth angle, or the drawing of the tooth angle characteristics of the grinding roller surface does not meet the quality requirements, it may lead to inappropriate selection of the grinding roller tooth angle, further reducing the grinding efficiency.
2. Excessive material humidity is also an important factor affecting the working efficiency of Raymond mill. When the material contains a lot of water, it is easy to adhere to the inside of the mill and even block the feeding and conveying system, thereby reducing the grinding capacity. Therefore, controlling the humidity of the material is one of the keys to improving the efficiency of Raymond mill.
3. Inadequate cleaning of the Raymond mill after use will also lead to reduced efficiency. If the number of cleaning equipment process passes does not meet the standards of three screenings and two beatings and one stone removal and one material washing, the material is not handled cleanly and contains a large amount of impurities, which will seriously affect the working efficiency of the mill. Therefore, regular cleaning and maintenance of equipment is an important measure to ensure the efficient operation of the Raymond mill.
4. The adjustment of air volume also has an important impact on the working effect of the Raymond mill. The air volume control valve should be reasonably adjusted according to the needs of the equipment fineness and output. It is necessary to prevent the material from settling in the air duct due to too small air volume, and to avoid the fineness from becoming coarse due to too large air volume. By reasonably adjusting the air volume, the output and fineness of the mill can be improved.
5. The fineness of the Raymond mill can be achieved by adjusting the analyzer speed and air volume. Generally speaking, the higher the speed, the higher the fineness, and the lower the speed, the coarser the fineness; the fineness is coarse when the air volume is large, and the fineness is fine when the air volume is small. Therefore, in actual operation, the analyzer speed and air volume should be flexibly adjusted according to the characteristics of the material such as size, hardness and specific gravity to achieve the best grinding effect and output.
