As one of the more popular milling equipments currently used, Ultrafine mill have been widely recognized by users for their excellent performance. However, the smooth production of ultrafine grinding mills directly affects the production of ore milling plants. Benefits, so it is necessary to properly maintain the mill, master some of the more common faults and solutions of ultra-fine mill is to help users fully understand the best magic weapon Ultrafine, the following Shanghai SBM summary for the majority of users What are the common faults and solutions for some ultra-fine mills?
First of all, the most common is the failure of the bearing wear of the ultra-fine mill. The reason for the bearing wear of the ultra-fine mill is that the bearing is mixed with impurities, which makes the friction increase and wear; the other is the bearing bearing is too large. This leads to increased friction and wear. The last reason is that the lubrication of the bearing is not in place. To solve the above three problems, the first need to always lubricate the bearing, the role of lubrication is mainly to reduce the friction between the bearing and other components in the mutual movement, thereby avoiding the bearing wear failure; In addition, when the bearing load exceeds a specific value After fatigue is used, the user needs to replace it in time and be careful not to allow the machine to operate with fatigue. In addition, because the working environment of the ultra-fine mill is rather harsh, some impurities will be mixed into the bearing. It is unavoidable that the user needs to do a timely cleaning of bearings, regular lubrication, and good sealing work.
After the failure of the bearing is solved, the next step is the breakdown of the vibration of the ultrafine mill. There are three reasons for this problem. First, it may be because the high-hardness material enters the grinding chamber of the machine. The ultra-fine pulverizer vibrates and generates a loud sound. To solve this problem, it is necessary to control the type of material entering the grinding chamber to eliminate the malfunction. Second, because the feed size is too large, when the size of the material entering the machine grinding chamber is too large, the machine consumes more energy to grind large materials, so it needs more grinding power to grind the material, and when When the power exceeds the maximum strength that the machine can withstand, it will inevitably cause product vibration, and because the material will break and the flour will make a sound, it will produce a loud sound, but this sound will continue for a little while, So don’t worry too much about it. Thirdly, it is related to the stability of the machine. We all know that ultra-fine pulverizers are cemented on the concrete foundation through foundations, bolts, etc. If cracks or loose bolts occur in this fixing method, it will also lead to The machine vibrates with the sound, and to solve this problem, it is only necessary to reinstall the machine and re-cast the concrete foundation.
Another problem is also more common, that is, the problem of excessive temperature of the ultrafine pulverizer. To solve this problem, you can first check whether the extension pipe is unimpeded, the viscosity and the grade of the oil meet the requirements; the roller bearing into the powder bearing should be timely refueling according to regulations, regular cleaning, replace the oil seal; grinding roller ring bearings to be regularly refueling .
