What are the easy-grinding parts of the Raymond mill?

Raymond mill is a commonly used grinding and milling equipment. Raymond mill is suitable for the grinding of more than 300 kinds of non-flammable and explosive materials with a Mohs hardness of less than 9.3 and a humidity of less than 8 percent. machining. And the use of vertical structure, small footprint, the number of mesh can be adjusted at will, and so on, deeply loved by the majority of users, the sales of Raymond mill has been steadily rising in recent years. So what are the easy-grinding parts of Raymond Mill, how to improve their wear resistance? Here is a small series for everyone to introduce in detail, I hope to help everyone.


The principle of Raymond mill is that the roller material is rolled on the grinding ring under the action of centrifugal force. The scraping material is sent to the middle of the grinding roller and the grinding ring by the blade, and the material is broken into powder under the action of rolling pressure, and then acts as a fan. The powdered material is blown up through the analysis machine, and the material that meets the fineness requirement passes through the analysis machine, and the heavy grinding chamber is not required to continue grinding. Discharge after meeting the requirements. In this process, Raymond Mill saves 30% to 40% more electricity than other milling equipment, which can greatly reduce the cost of use. The easy-grinding parts of Raymond mill are the blade, the grinding roller and the grinding ring. These three are the three easy-grinding parts of Raymond mill, which directly contact the grinding of the material.


So how do you slow down the wear and tear of these three easy-to-wear parts? First of all, we need to know which factors are related to the wear: the hardness of the material, the harder the material is, the higher the degree of wear, and the lower the hardness of the material, the less wear on the grinder. For higher hardness materials, it is necessary to choose a better abrasive parts, such as manganese 13, or a better high-chromium alloy material grinding ring. In the case of ensuring the efficiency of the powder, the speed of the Raymond mill is reduced as much as possible, so that the power consumption can be reduced, and the wear level can be effectively reduced to prolong the service life. It is necessary to regularly repair the wearing parts and replace the worn parts to ensure the best condition of the Raymond grinding.
