Analysis of the cause of the ultra-micro gas flow crushing machine

　　Airflow milling for drugs, the drug particles after micronization mainly include: increase the specific surface area of ​​the powder powder, a more compact PSD (particle distribution size), more uniform size, better powder control characteristics ( Suspension, dispersion and absorption), more predictable powder properties, color consistency, gloss, opacity.Bearing is

　　, which directly affects the normal operation and production efficiency of the device. The bearing fever is a common fault of ultra-micro gas flow. The main causes of the occurrence are as follows:

　　1, lubricating oil excessive, too small, contamination Deteriorate. If the lubricating oil is unqualified, it is one of the main reasons why the bearing is overheated. Therefore, in order to quantify the binder in the bearing box according to the standard timing, it is generally lubricated 70% -80% of the bearing space, excessive or too little is not conducive to bearing lubrication and heat transfer. If it is contamination, be sure to clean the bearing box and then inject new lubricants.

　　2, the bearing housing is low. This situation also affects the motor rotor of the ultra-micro gas flow crusher and the pulverizer rotor, so that the shaft is subjected to an additional load, causing the bearing overheating. This happens, you have to shut down immediately, troubleshoot, avoid early damage to the bearing. 3, the pulverizing machine bearing cover is too tight. The bearing and the axis of the shaft is too tight or too loose. One, this problem occurs, in the operation of the equipment, the sound of friction and obvious swing will be issued. At this time, the bearings should be removed immediately, and the wear portion is repaired, then re-assemble it as required.

　　During the operation of the ultra-micro gas flow pulverizer, when the bearing is heated or noise, it should be closed in time, and then enabled after troubleshooting.

　　Sincere cooperation, work together, Shandong ALPA powder technology and a number of well-known enterprises have not only provided a power for China's economic expansion, but also for the performance of Shandong ALPA powder technology. A bright. In the future, Shandong ALPA Powder Technology will continue to play its own advantages in the manufacturing field of industrial powder, provide high-quality powder equipment, laying a solid hair in more enterprises.Exhibit.
