The composition of high-quality Raymond mills is indispensable for Raymond mill accessories purchase: In general, Raymond mill accessories are composed of main engine, analyzer, fan, finished cyclone separator, fine powder cyclone and air duct. Each Raymond mill accessory blows it into the main machine and sorts it in the analyzer in the grinding chamber. The unqualified material will fall into the grinding chamber and re-grind. The qualified grinding will enter the collector with the wind flow, and finally the powder tube Out, unqualified raw materials are circulated and ground in the Raymond machine in this way, and are discharged after reaching the requirements. From the point of view of Raymond mill accessories purchase, the harder the parts, the more wear-resistant, so it is seemingly simple to make the more wear-resistant Raymond mill parts.
Many foundries flaunt their castings with 30% chromium content. The HRC hardness has reached 63-65, but it is not. Grinding rolls and disc liners are generally made of high-chromium cast iron or nickel-chromium alloy, but this material often breaks, causing considerable damage, especially the loss of production, it is impossible to estimate. According to the expert's identification, the higher the hardness of the Raymond mill fittings, the more the number of carbides contained in the castings is required, and the more dispersed the distribution, the greater the probability of forming microvoids and microcracks at the interface between the matrix and the carbide. The chance of breaking will also increase. Therefore, it is necessary to grasp this degree in order to make a truly wearable Raymond mill fitting. The problems that occur in daily grinding sticks are: bearing damage, there may be two main reasons for the problem: one is oil cut, the seal is broken, and the other is long-term lack of maintenance and cleaning. The grinding rod device is used for more than 500 hours. When re-replacement of the grinding stick, the rolling bearings in the rolling sleeve must be cleaned and the damaged parts replaced. The refueling tool can be used with a manual refueling pump or a grease gun.
The most vulnerable parts of Raymond mill are the grinding stick and the grinding ring. The grinding sticks and grinding rings produced by our company all use wear-resistant materials. According to the process requirements and load characteristics of Raymond mill, the bearing requirements have the following: 1) In order to ensure the rotation precision of the grinding roller, the bearing must have a high matching precision. 2) In order to adapt to the deformation of the grinding roller to reduce the assembly requirements, the bearing is required to have a certain self-positioning performance. 3) The bearing structure should be easy to assemble and disassemble, so that the grinding roller can be removed and removed. 4) Considerable load capacity and vibration resistance. 5) Good enough heat dissipation.
