Chinese medicine superfine pulverizer can strengthen the utilization of materials and reduce the waste of resources. It is continuously applied in the field of medicine. Relevant enterprises should combine market demand with high technology to develop more powerful and practical Chinese medicine pulverizer equipment. In order to effectively promote the growth and sustainable development of the ultra-fine crushing industry. At present, there are still some minor problems in the aircraft, which require users to find timely and timely processing.
1. The temperature is too high;
Most of Chinese herbal medicines have active ingredients. In the pulverization process, there is a high requirement for temperature. If the impact force caused by high rotation speed is pursued, the temperature is too high and the medicinal materials are invalid.
2. Not easily stressed;
Most of the Chinese medicinal materials are plants, which are various in variety and different in nature. A large part of them are rich in fiber and light in weight, and are not easily subjected to mechanical force in the pulverizing machine.
3. The wall breaking effect is not good;
The cell diameter of Chinese medicinal materials is generally between 10 and 50 microns, and some of them reach 70 microns, so they are pulverized to two or three hundred meshes. Only some cells begin to break the wall. To achieve the purpose of improving the efficacy, the wall should be fine. It is more appropriate to set the bottom line to 500 mesh (equal diameter of 25 microns). Nowadays, the general ultrafine pulverizer is difficult to meet this requirement for Chinese medicinal materials.
4. The bearing is overheated;
Many users will find the bearing overheating when using the traditional Chinese medicine ultrafine pulverizer. It is understood that there are many reasons for the bearing overheating, such as when the two bearing housings are uneven, or when the rotor of the motor is not the same as the rotor of the destroyer, The bearing is subjected to an additional load and then causes the bearing to overheat. In this situation, it is necessary to stop the machine immediately to eliminate the fault and avoid the damage of the bearing in the early stage.
Too much, too little or aging of the lubricating oil in the bearing is also the primary cause of overheating and damage of the bearing. The lubricating oil should be filled in time according to the requirements of the application. Generally, the lubrication accounts for 75%-80% of the bearing space, too much or Too little is not conducive to bearing lubrication and heat transfer.
When the bearing cap and the shaft are too tightly fitted, the bearing and the shaft are too tight or too loose, which may cause the bearing to overheat. Once this problem occurs, the friction sound and obvious sway will occur during the operation of the equipment. Remove the bearings from the machine, trim the friction parts, and reassemble as required.
5. The output value decreases;
There is a user reaction, and the output value drops after the machine has been working for a while. There are many reasons for the decline in the output value of the crusher, such as too much moisture in the material, poor discharge of the destroyer, improper size of the screen mesh, and factors such as fan equipment can affect the output value of the destroyer.
Too much moisture in the material will affect the efficiency of the machine. Materials with too much moisture are not easily crushed, and the mesh of the screen is simply blocked, which seriously affects the output value of the machine. The treatment of this condition is to dry the material or to dry it before pulverizing.
6. Blockage problem;
If there is a blockage at the discharge port, it will affect the discharge speed of the destroyer, resulting in a decrease in output value. The treatment of this condition is to clean the discharge port, including the residual material inside the chamber, to ensure the smoothness of the entire destruction.
The pore size of the screen is also an important factor in controlling the particle size. If the particle size required for pulverization is not the same, the screen with different pore sizes should be replaced, otherwise the efficiency of the failure will be reduced, or the unqualified particles will be produced. The opening rate of the screen affects the filtration speed of the screen. When the opening ratio is too small, the efficiency of the destruction machine naturally decreases. The problem of the reduction in the output value caused by the problem of the pore size of the screen is to replace the screen with the appropriate pore size and opening ratio.
Blockage is one of the more common problems of ultrafine grinding equipment. It may also be a problem in the design of the machine during use. However, it is more due to the increased load caused by improper operation, and the feed rate is too fast, causing blockage. During the feeding process, always pay attention to the large deflection angle of the ammeter pointer. If the rated current is exceeded, it indicates that the motor is overloaded and overloaded for a long time, which will burn the motor. In this case, the door should be immediately reduced or closed, and the way of feeding can be changed. The feeder is controlled to increase the amount of feed.
Due to the high speed of the machine, the load is large, and the load is shaken strongly. Therefore, the current during operation is generally controlled at about 85% of the rated current. If it does not meet the requirements, the air vent of the machine will be blocked. If the matching with the conveying equipment is improper, the wind of the discharge pipe will be weakened or blocked after the wind is not found. When the discharge pipe is not smooth or the feed port is blocked, the feed port should be cleared first, and the feed amount should be adjusted to make the equipment operate normally.
In order to better use the Chinese medicine superfine pulverizer, if you notice the above problems during the operation, don't ignore it.
