With the continuous improvement of milling technology, various types of milling equipment are also increasing. Common milling equipment includes Raymond mill, superfine mill, vertical ring roller mill, high pressure mill and other different equipment. From the appearance point of view, the differences between these types of pulverizers are not big, so users will have doubts when choosing equipment. For ultra-fine grinding, what are the advantages of this equipment compared with Raymond mill? The following is an introduction to the advantages of ultra-fine mills.
1. At present, Raymond Mill is a relatively mature model in the milling industry. The superfine mill is an improved milling equipment based on the traditional Raymond mill. Relatively speaking, ultra-fine grinding has higher technical and process advantages for Raymond mills.
2. Whether it is superfine grinding or Raymond grinding, the basic principle is the same when processing materials. All materials are sent between the grinding roller and grinding ring, and then under the action of gravity and the centrifugal force of the grinding roller, the material is rolled to achieve the effect of grinding powder.
3. However, the ultra-fine grinding has a more significant advantage than the Raymond grinding in the internal structure. For example, the blade of the traditional Raymond pulverizer is an integrated device. When it is worn and needs to be replaced, the whole set needs to be replaced, which greatly increases the maintenance cost. The superfine grinding only needs to replace the worn blades, thereby reducing maintenance costs.
4. The lubrication form of traditional Raymond mill is grease lubrication. In the grinding operation, the lubrication resistance is higher, the temperature rise is also higher, and the life of the bearing will be relatively reduced. The ultra-fine grinding adopts an internal thin oil lubrication system, which can realize the lubrication of the main shaft bearing and gear bearing without adding an additional oil pump or lubrication station, thereby greatly improving the service life of the equipment.
