When we use Raymond mill to grind the powder, we need to regularly add grease to the raymond mill bearing parts. Because in the process of Raymond grinding, not only the friction between the material and the main shaft, but also the frictional resistance of the joint parts of the parts, the main function of the lubricating oil is to reduce the frictional resistance between the parts. If the lubricating oil is insufficient, the friction of the main shaft will increase, and the temperature will rise too high, which will cause thermal deformation. In this case, combined with a large number of practices, it is found that the temperature rise of the bearing using the oil and gas lubricant can be reduced by 5-8 ° C and the grease lubrication by 9-16 ° C compared with the use of oil mist lubrication. As the value increases, the effect of cooling will be more pronounced. Oil and gas lubrication technology has been effectively applied to the super high speed Raymond grinding spindle and achieved good results. Ultra-fine Raymond machine is also a kind of Raymond mill. The difference between it and ordinary Raymond machine is that the fineness of grinding is very different, and its application range is wide. Common kaolin, limestone, coal and stone Etc., as well as calcite, barite, iron oxide red, iron oxide green, aluminum hydroxide, pigment, bentonite, etc., can use ultra-fine Raymond machine for ultra-fine powder processing.
After learning about the importance of lubricants to Raymond Timo, let's take a look at the reasons that affect the life of Raymond mills.
The reasons for affecting the life of raymond mill are as follows: 1. Due to improper installation or poor material, the large and small blades often fall off or break during the operation of the classifier. When the small blades fall off or break, the fineness of the finished product becomes thicker. This situation should be stopped and the small fan blades should be updated. 2. The sleeve liner of Raymond mill is easy to wear due to the impact of materials for a long time. If the replacement is not timely, the inner sleeve will wear and form a hole. It can be seen that there are two main factors that determine the service life of the Raymond mill. One is the quality of the Raymond mill manufacturing process, and the other is the installation process, that is, the installation quality. With the economic loss caused by the damage of Raymond mill, the installation quality is particularly important, and even determines the service life of Raymond mill.
