Under the background of the rapid development of the Chinese medicine industry due to the favorable environment, the market prospect of Chinese medicine pulverizers is broad, and the team of its manufacturers is gradually increasing. Chinese medicine pulverizers are suitable for small Chinese medicine factories, Chinese medicine stores, Chinese medicine hospitals and other fields. Moreover, with the development of modern automation and intelligent technology, as well as the increasing market demand for traditional Chinese medicine products, many traditional Chinese medicine crushing equipment have been improved and upgraded in the direction of higher automation, higher work efficiency, and simpler operation to further meet user needs.

However, users often encounter some problems in the process of using traditional Chinese medicine pulverizers, which affect the production of traditional Chinese medicine pulverization and the quality of products. Specifically, there are mainly the following problems, which are briefly analyzed.

Agglomeration phenomenon in crushing

How to solve the phenomenon of reunion is a problem that needs to be solved in the process of crushing traditional Chinese medicine. It is reported that dispersants (surfactants) play a very important role in the grinding process. If the ground materials can be fully dispersed, there will be no agglomeration, so the so-called reverse grinding phenomenon will not occur. Therefore, the proper choice of dispersant is an effective way to solve the problem of inverse grinding.

The industry reminds that for most materials, the longer the crushing time of the traditional Chinese medicine grinder, the better the crushing effect. Otherwise, sometimes some materials reach a certain fineness, but it is not easy to crush; sometimes the particle size of the material increases instead.

production decline

Many users reported that the output of the traditional Chinese medicine grinder decreased after working for a period of time. What is the reason? According to the industry, there are many reasons for the decline in the output of the pulverizer, such as too much moisture in the material, poor discharge from the pulverizer, inappropriate screen aperture size, fan configuration and other factors can affect the output of the pulverizer.

For example, too much moisture in the material will affect the efficiency of the pulverizer. "Materials with too much moisture are not easy to be crushed, and it is easy to block the mesh of the screen, which seriously affects the output of the crusher." According to the industry, the solution to this situation is to dry or dry the materials before crushing .

Blockage of the discharge port The blockage of the discharge port will affect the discharge speed of the pulverizer, resulting in a decrease in output. The solution to this situation is to clean the discharge port, including the residual materials inside the crushing chamber, to ensure the smooth flow of the entire crushing process.

The pore size of the screen is also an important factor in controlling the crushing particle size. According to the industry, when the particle sizes required for crushing are different, the screens with different apertures should be replaced, otherwise the crushing efficiency will be reduced, or unqualified particles will be produced. On the other hand, the opening ratio of the screen affects the filtering speed of the screen. When the opening ratio is too small, the efficiency of the pulverizer will naturally decrease. The solution to the decrease in production due to the size of the pore size of the screen is to replace the screen with a suitable pore size and opening ratio.

In addition, the problem of air pressure configuration will also lead to a decrease in production. It is understood that the rotor in the pulverizer will form a low-pressure area in the pulverization chamber during operation. The material is affected by the atmospheric pressure and is not easy to fly out of the pulverization chamber. The purpose of configuring the pressure difference is to artificially increase a low pressure area outside the pulverization chamber. In the crushing area, the pressure difference between the inside and outside of the crushing chamber disappears, and the discharge speed of the material is naturally increased. The solution is to configure a reasonable fan for the pulverizer.

Bearing overheating

Many users will overheat the bearing when running the traditional Chinese medicine grinder. Is this a normal phenomenon?

It is understood that there are many reasons for the overheating of bearings. For example, when the two bearing seats are uneven, or the rotor of the motor is not concentric with the rotor of the pulverizer, the bearings will be impacted by extra loads, which will cause the bearings to overheat. In this case, stop the machine immediately to eliminate the fault, so as to avoid early damage to the bearing.

"Too much, too little or aging lubricating oil in the bearing is also the main cause of overheating and damage to the bearing. Lubricating oil should be added on time and quantitatively according to the requirements of the instruction manual. Generally, lubrication accounts for 70%-80% of the bearing space. Or too little is not conducive to bearing lubrication and heat transfer." The industry said so.

In addition, when the fit between the bearing cover and the shaft is too tight, the fit between the bearing and the shaft is too tight or too loose, which will cause the bearing to overheat. Once this kind of problem occurs, there will be friction sound and obvious swing during the operation of the equipment. At this time, the operation should stop and remove the bearing, repair the friction part, and then reassemble as required.
