The use and maintenance of the third generation Raymond mill

The use and maintenance of the third generation Raymond mill

1. During the work process, raymond mill should have fixed personnel to take care of the machine. The operator must have certain technical knowledge and level. The user must carry out the operation and maintenance and electrical and other personnel before the installation of Raymond mill according to the specific conditions of the factory. Technical training, to achieve a certain level of familiarity with the performance and principles of this machine, in order to operate.

2. The user unit shall formulate equipment maintenance and safety system according to the use of Raymond mill to ensure that Raymond mill can operate safely for a long time.

3. In addition to some models, the upper part of the main shaft adopts sliding bearings, and the other transmission parts adopt rolling bearings. Therefore, it must be operated under good lubrication conditions, otherwise the bearing will be damaged and the service life will be shortened. See the lubrication system table for the specific refueling time and the type of grease.

4. It is forbidden to enter the metal block and find that it will be stopped immediately, otherwise the grinding roller and the grinding ring will be damaged.

5. The feeding should be uniform, not too much. Excessive feeding will block the air duct, reduce the output, and easily burn out the motor. If the feeding is too small, the output will be reduced. The feeding granularity refers to Table 1. It is strictly forbidden to add large materials into the machine.

6. Air volume adjustment: The air volume control valve located on the air intake pipe of the fan is generally opened to the maximum position and adjusted according to the fineness and output requirements. The air volume is small and the fineness is high. However, it should be noted that the air volume is too small, and the material in the air duct below the main unit is easy to precipitate. Please adjust it properly. The regulating valve located on the outlet dust pipe of the fan can be adjusted to the dust-free discharge at the feeding port during normal operation.

7. Fineness adjustment: According to the size of the material, the hardness, water content and specific gravity are different, and the processing thickness is also different. The upper analyzer can be adjusted, and the rotation speed is high, the fineness is high, the rotation speed is low, and the fineness is low. Increase the fineness, the output will be reduced accordingly, if the wind turbine volume and speed should be debugged if the requirements are not met, the user can flexibly master.

8. The grinding roller ring is scrapped and the remaining minimum wall thickness shall not be less than 10mmm.

9. When stopping, first stop feeding, the main machine will continue to run, so that the residual material will continue to be ground. After about one minute, the main motor and analyzer motor can be turned off, the grinding operation is stopped, and then the fan motor is stopped to blow. A net residual powder.
