At present, the so-called new products of Chinese medicine ultrafine pulverizing equipment emerge one after another. The common purpose of the machines of various principles is to smash the Chinese medicine more finely, and the complexity of the nature of traditional Chinese medicine determines the pulverizer product that is suitable for its different principles according to its nature. Faced with a wide variety of traditional Chinese medicine superfine pulverizer products, how to choose the right model has become a very concerned issue for our customers. The pulverization principle of each type of superfine pulverizer is different, and the nature of pulverized materials is more diverse. The difficulty in choosing a crusher, how to choose a superfine grinder. Then we must first understand the definition of superfine shredder , and it may be a good way to choose the model from its definition.
Superfine pulverization is a high-tech that has developed rapidly in the past 20 years. It can process raw materials into micron or even nano-sized micro-powder, which has been widely used in various industries. In view of the fact that smashing is the basic processing technology in the production and application of traditional Chinese medicine, ultrafine pulverization has attracted more and more people's attention. Although the technology started late, the developed varieties are relatively few, but it has revealed its unique advantages and broadness. Application prospects.
Ultrafine pulverization technology is an important part of powder engineering, including ultrafine pulverization of powder raw materials, high-precision grading and surface activity change. According to the size or particle size of the raw materials and finished particles, the pulverization can be divided into coarse pulverization, fine pulverization, fine pulverization and ultrafine pulverization, which is a rough classification. It is worth noting that the size of the ultrafine powders is differently divided in various industries in various countries due to the use of ultrafine powders, the difference in preparation methods and technical levels. The ultrafine pulverizer is generally a sieveless pulverizer. The particle size of the pulverized material is controlled by the gas flow rate. The pulverization particle size requires 95% to pass 0.045 mm (325 mesh, that is, 45 μm), and is generally used for special aquatic bait or aquatic open bait. The ultrafine pulverizing system is usually completed by an ultrafine pulverizer, pneumatic conveying, and classifier. The pulverized particle size of the raw material is very fine, which may show unexpected characteristics, but it also brings more problems, such as electrostatic adsorption, poor fluidity of the material, large energy consumed by pulverization, increased production cost, and influence on processing operations. Larger, these adverse effects can be overcome in different ways (such as changing the feed processing process).
Ultrafine pulverization is achieved by means of impact, collision, shearing, grinding, dispersion, etc. of the material. The extrusion pulverization method in the conventional pulverization cannot be used for ultrafine pulverization, otherwise granulation effect will be produced. When selecting the pulverization method, it depends on the nature of the pulverized material and the required pulverization ratio. In particular, the physical and chemical properties of the pulverized material have a great influence, and the hardness and rupture of the material are more important. For hard and brittle materials, the impact is very effective; while the Chinese herbal medicine is better for grinding and shearing. In fact, any kind of pulverizing machine is not a simple pulverizing mechanism. Generally, two or more pulverizing mechanisms are combined to pulverize. For example, a jet mill is pulverized by mutual impact and collision of materials; The high-speed impact pulverizer is the impact and shear pulverization; the pulverization mechanism of the vibration mill, the agitator mill and the ball mill is mainly grinding, impacting and shearing; and the working process of the colloid mill is mainly through the high-speed rotating grinding body and the fixed grinding machine. Strong shear, friction, shock, etc. produced by the relative motion of the body.
The development of traditional Chinese medicine superfine pulverizers has been going on for many years. From the imitation of Zui's initial to the current innovative research and development, from the application of individual industries to the popularization of related industries, the superfine pulverizer has already had a very strong crushing ability, after superfine pulverization. After the Chinese medicine can easily reach the level of cell breakage, the absorption rate of traditional Chinese medicine will be greatly improved. This technology has a bright future in the utilization of precious Chinese medicine, which is important for protecting rare Chinese medicine varieties and improving utilization rate. The same, the same for the plant extract industry is also a good way to increase production efficiency and reduce production costs. As a company specializing in the R&D and production of ultrafine pulverizers, Zhongke Nichi Technology (Beijing) Co., Ltd. is eager to see that the advanced equipment of ultrafine pulverizers has entered a different role in different industries.
