General Knowledge for Raymond Mill Maintaining2018-06-13
Raymond mill also be called Raymond roller mill, it’s popularity by high efficiency, good quality, energy saving and many advantages. It has a strong ability to process more than 200 kinds of stone materials grinding. However, if we don’t take good care of our Raymond mill, it will appear some trouble after a short of time using. So what’s should we do when we use the Raymond mill to process the stone powder.
1. When Raymond mill at working there should be managed by fixed personnel during the working process. The operator must have certain technical knowledge and level. In accordance with the specific conditions of the mill, the user must carry out technical training for the personnel concerned, such as operation maintenance and electrical equipment before the mill is installed, to a certain degree of familiarity with the performance and principle of the machine. Operation.
2. The user unit should make equipment maintenance and safety system according to the use of Raymond mill, ensure that the mill can run safely in the long run.
3. Besides the sliding bearing on the upper part of the main shaft, the rolling bearing is adopted in the other transmission parts. Therefore, it is necessary to operate under good lubrication conditions, otherwise the bearing will be damaged and the service life will be shortened. The specific time of refueling and the variety of grease are shown in the lubrication system table.
4. Strictly prohibit the metal blocks from entering the machine and find that the machine will be shut down immediately, otherwise the grinding roller and grinding ring will be damaged.
5. Added material should be uniform, not negligible and less. Too much feed will block the air duct, reduce the output, easily burn out the motor, too little feed will also reduce the output, feed grain size reference table 1, strictly prohibit large mass of material into the machine.
6. Air volume adjustment: the air volume control valve located on the intake pipe of the fan is generally open to the maximum position, and is adjusted according to the fineness and output requirements. The air volume is small and the fineness is high. However, it should be noted that if the air volume is too small, it is easy to adjust the material in the air duct below the main engine. The regulating valve located on the outlet dust pipe of the fan is transferred to normal operation without dust ejection at the inlet.
7. Fineness adjustment: according to the size of the material, the soft and hard, the water content, the specific gravity are different, the processing is different, can adjust the above analyser, high speed, high fineness, low speed, low fineness. If the fineness is increased, the output will be reduced correspondingly. If the wind speed and volume of the fan are not met, the user can control it flexibly.
8. The scrap limit of grinding roller grinding ring, the remaining minimum wall thickness should not be less than 10mmm.
9.When we turn down the Raymond mill, the feed is stopped and the main engine continues to run. The residual material continues to be lapping. After about one species, the mainframe motor and the analyzer motor can be closed, the grinding work is stopped, and then the fan motor is stopped to purge the residual powder.
