Daily use and maintenance of carbon black mill


The carbon black pulverizer must be regularly maintained during its use. Basically, it is divided into small maintenance, medium maintenance and large maintenance. Good maintenance is good for the service life of the pulverizer. So how to maintain the carbon black mill in daily use? What problems should we pay attention to? Shanghai Joyal Mining Machine provides a few examples of the daily maintenance of the carbon black mill, hoping to help you.
1. The upper end of the main shaft of the carbon black mill uses sliding bearings or copper sleeves, and the rest of the transmission parts use rolling bearings, so it must be operated under good lubrication conditions, otherwise the bearings will be damaged and the service life will be shortened. The maintenance methods are as follows:
The main shaft refueling time is twice per shift, but it must be noted that when the oil in the oil cup is found not to be worn out or the loss is too slow, the oil passage should be cleaned immediately. Add 50# mechanical oil, the oil cup is located at the upper end of the spindle, the spindle base bearing and the grinding roller bearing are filled with 5# calcium-based grease with a grease gun for each shift, and the fan bearing chamber is filled with lithium-based grease.
2. It is strictly forbidden for metal blocks to enter the machine. If found, stop the machine and take it out immediately, otherwise the grinding roller and grinding ring will be damaged or the plum blossom frame will be deformed.
3. The feeding should be uniform, not too much or too little. Too much feeding will block the air duct, reduce the output, and easily burn out the motor. Too little feeding will also reduce the output. It is strictly forbidden to add bulk materials into the machine.
4. Air volume adjustment: The air volume control valve located on the air intake pipe of the fan is generally opened to a large position and adjusted appropriately according to the fineness and output requirements. The regulating valve located on the exhaust pipe of the exhaust gas outlet can be adjusted so that no dust is ejected at the feeding port, the air volume is small, and the fineness is high. However, it should be noted that if the air volume is too small, materials are easily deposited in the air duct below the main unit, so please adjust it appropriately.
5. Fineness adjustment, according to the size, hardness, water content and specific gravity of the material, the thickness of the processing is also different, the analyzer above can be adjusted, the speed is high, the fineness is high, the speed is low, and the fineness is low. If the fineness is increased, the output will be reduced accordingly. If the requirements are not met, the user can flexibly control the speed of the fan correspondingly.
6. The scrapping limit of the grinding roller ring: the remaining small wall thickness shall not be less than 10mm.
7. When stopping, first stop feeding, and the main engine continues to run, so that the residual abrasive continues to grind. After about one minute, the main engine motor and analyzer motor can be turned off to stop the grinding work, and then stop the fan motor. to blow off any remaining powder.
