Raymond vertical mill is also called calcite milling machine. It is suitable for all kinds of mineral powder preparation, coal powder preparation, such as fine powder processing of raw material mine, gypsum mine, coal and other materials. Now with the development of the mining industry, there are many types of grinding equipment in the mine development site to process ore. When we understand and use the grinding equipment, we will find that the bearings of the grinding equipment will appear after a period of use. Fever, don't panic at this time, the editor will take you to understand the structural characteristics of the milling equipment.
Raymond Vertical Mill
Structural characteristics of the Raymond vertical mill
1. Most of the milling equipment has a three-dimensional structure, a small footprint, and a strong set. From the bulk material to the finished powder, it independently forms a production system.
2. The fineness of the finished powder is even, and the screening rate is 99%, which is difficult for other milling equipment.
3. The transmission device of the main machine of the pulverizer adopts a closed gear box and a pulley, and the transmission is stable and the operation is reliable.
4. The important parts of the mill are made of high-quality steel, and the wear-resistant parts are made of high-performance wear-resistant materials. The whole machine has high wear resistance and reliable operation.
5. The electric system adopts centralized control, the grinding workshop can basically realize unmanned operation, and the maintenance is convenient.

The main supporting part of the operation of the mill is the bearing. The bearing is also the main factor affecting the performance and production efficiency of the Raymond vertical mill. The user must pay special attention to the temperature of the bearing and the noise of the bearing to avoid abnormal phenomena and affect the normality of the machine Run. The following are the causes and solutions of bearing heating summarized by everyone.
1. Too much or too little lubricating oil will cause the bearing to heat up. If it is overheated, due to poor heat dissipation performance, the generated heat cannot be radiated in time; and too little will not completely lubricate the bearing. When running, the bearing will become hot. When adding lubricating oil to the bearing, it is generally better to use lubricating oil for about 70% of the space. Too much or too little is not conducive to heat dissipation of the bearing.
2. The height of the bearing is different, or the rotor of the motor and the rotor of the mill are not concentric, which will cause additional shocks of the bearing, resulting in overheating of the bearing. If this phenomenon occurs, you should immediately adjust the position of the bearing to avoid the position being out of concentricity, resulting in the phenomenon of partial wear.
3. The cooperation between the bearing and the bearing seat of the mill is too tight. If the bearing and the bearing seat are too tight, the wear will increase. If the bearing is too loose, the bearing will overheat. If this problem occurs, the tightness of the bearing and the bearing seat must be adjusted. Degree, refit.
Raymond Vertical Mill
There are three main points of overheating of the bearing of the mill. The amount of lubricating oil, the bearing and the motor are not concentric, and the bearing and the bearing seat are too tightly matched. After reading it, do you think it is very easy to solve it? There are many tips and tricks that will be sorted out for you. If you want to know more about the grinding equipment, please call for detailed consultation.
