Ultra -micro crushing technology and its application introduction

Ultra -micro crushing is a high -tech that has developed rapidly in the past 20 years. It can add 10 % microns and even nano -level microfimm that can be added in all walks of life. In view of the basic processing technology in the production and application of Chinese medicine, ultra -micro crushing has become increasingly attracting people's attention. Although it starts late, the development and development varieties are relatively small, but it has revealed unique advantages and broad application prospects. Essence The manufacturers of Shandong Character Character below will introduce the ultra -micro crushing technology and its applications for everyone.

1. Overview of ultra -micro crushing technology

Ultra -micro crushing technology is an important part of the powder engineering, including ultra -ultra -superior raw materials for powder materials, Micro crushing, high -precision classification and surface activity changes. According to the size or particle size of the raw materials and finished particles, crushing can be divided into rough, fine crushing, slightly crushing and ultra -microfinance, which is a rough classification. It is worth noting that due to the use of ultra -micro powder, the differences in preparation methods and technical levels, various industries and industries and various industries have different granularity of the super microfinance.

Ultra -micro crushing machines are generally sieve -free pieces, and the particle size is controlled by the gas flow rate. The crushing particle size requires 95%through 0.15mm (100 mesh). Ultra -micro crushing is usually completed by ultra -micro crushing machines, power transportation, and classifiers. The crushing particle size of the raw materials may show unexpected characteristics, but it also brings more problems, such as static electrostatic adsorption, poor liquidity of the material, large energy consumption, which increases production costs, the impact of processing operations on processing operations It is relatively large, these adverse effects can be overcome by different methods (such as changing feed processing processes).

Ultra -micro crushing is achieved through the impact, collision, cutting, grinding, dispersion and other means. The squeezing and crushing method of traditional crushing cannot be used for ultra -micro crushing, otherwise it will produce grain effect. When choosing a crushing method, it is necessary to depend on the nature of the shattering material and the required crushing ratio, especially the physical and chemical properties of the crushed materials have a great decisive effect, and the hardness and rupture of the material are the primary position of the more primary position For hard and brittle materials, the impact is effective; while grinding and cutting methods for traditional Chinese pharmaceutical materials are better. In fact, any kind of crushing machine is not just a certain crushing mechanism, generally combined with two or more crushing mechanisms for crushing, such as the airflow crusher is crushed with the mutual impact and collision of the material; High -speed shocking pieces are shocking and cutting into crushing effects; the crushing mechanism of vibration grinding, mixing grinding and ball mills is mainly grinding, impact and cutting; The strong shear, friction, impact, etc. of the relative movement of the body.

2. Commonly used ultra -micro crushing equipment

2.1 Mechanical impact crusher is high, large, large, simple structure, operating, operatingStable, suitable for medium, the crushing machine of the soft and hardness materials not only has two crushing effects of impact and friction, but also has airflow crushing effects. Because the impact of ultra -fine powder products is running at high speed, we can wear wear, which must be worn. The problem, in addition, has the problem of fever, and take appropriate measures for the crushing of thermal substances. Zhejiang Favorite State Special Crusting Equipment Factory produces a series of crushing machines to increase air volume transmission materials. The heat transfer effect is good, the temperature of the crushing area is low, and it can be used for crushing Sichuan of certain thermal materials.

2.2 The airflow crusher is a carrier of compressed air or overheating steam through the supersonic high turbulence flowing air flow generated by the nozzle. Cutting and other functions to achieve the purpose of crushing. Compared with ordinary mechanical shock super microcomputers, the airflow crusher can crush the product very finely, the granularity distribution range is narrower, that is, the particle size is more uniform; because the gas swells at the nozzle, it can cool down, and there is no accompanying calories in the crushing process. So the shattering temperature is very low. This characteristic Liu Yu's ultra -micro crushing of low melting points and thermal materials is particularly important. However, there is also a problem: the equipment manufacturing cost is high, the one -time investment is large, the energy consumption is high, and the energy consumption rate is only about 2%. It has made it a certain restriction in the use of this field: at the same time, it is difficult to achieve the smashing of sub -micron -level products.

2.3 ordinary ball mill is a traditional equipment used for ultra -micro crushing. It is characterized by large crushing ratio, simple structure, strong mechanical reliability, easy to check and replacement of wear parts, mature craftsmanship, strong adaptability, product grain size Small. However, when the granularity of the product must reach 201 \u0026 mu; m, the efficiency is low, the energy consumption is large, and the processing time is long. For example, it takes ten hours to grind pearls to a few hundred meters.

2.4 vibration grinding grinding is to support the body with a spring support, which is vibrated by the main axis with eccentric blocks. During operation, it vibrates the medium and material. High, the number of times of the unit time is high (the number of shocks is 4-5 times the ball mill), so its efficiency is 10-20 times higher than that of ordinary ball mill, and the energy consumption is several times lower than its. By regulating the amplitude of vibration, vibration frequency, medium type. The average particle size of the vibration grinding products can reach 2-3 \u0026 mu; M is below the m, and it is easier to obtain a sub-micron-level product for substances with greater brittleness. In recent years, through practice, the vibration grinding has become increasingly valued. The reason is that the vibration grinding can reach the sub -micron level for certain material products. At the same time, it has a strong mechanical and chemical effect. Easy to produce industrial scale.

2.5 stirring and grinding is developed on the basis of the ball mill. Compared with ordinary ball mill, the mixing grinding uses high speed and high media filling ratio and small media size. The material grinding time is greatly shortened, and the energy utilization rate in the ultra -micro crushing machine is high,Very promising species equipment. The efficiency is greatly improved when mixing is less than 20 \u0026 mu; High -power density (high -speed) mixing grinding machine can be used for products below micrometers with large grain size, and it has been successful in pigments, ceramics, paper, coatings, and chemical products. At present, the large -scale application of high -power density stirring and grinding in industries has two major problems: processing ZUI small and high wear costs. With the emergence of high -performance wear -resistant materials, I believe these problems can be resolved.

3. Application of ultra -micro crushing technology in traditional Chinese medicine processing

3.1 The ultra -micro crushing of super microcros on Chinese medicine processing in Chinese medicine processing, currently mainly refers to cell -level micro -crushing. \u0026 quot; Cell -grade micro -crushing \u0026 quot; refers to crushing operations for the purpose of moving and plant medicinal cells, using modern ultra -micro crushing technology, the wall breaking rate of general medicinal cells under this detailed conditions reaches 95%. After the Chinese medicine cells break the wall, the following advantages are shown:

(1) Increase the drug absorption rate and increase its biological utilization.

The size of the drug particles and the structure of the powder are important factor affecting the absorption of the drug. After the traditional Chinese medicine is treated, its particle size is more subtle, increases from the surface area, the pore rate increases, the drugs can be dispersed well, dissolved in the gastrointestinal fluid, and the contact area of \u200b\u200bthe gastrointestinal dry membrane increases. Intestinal absorption, whether it is an external patch or an internal capsule, can use a smaller dose to achieve the original efficacy after super micro -crushing. Because the particle size is greatly reduced, it can be decided to dissolve in the body, absorb speed, and improve its absorption;

(2) Failure to retain biological activity ingredients and improve efficacy.

In the process of ultra -micro crushing, it can not produce overheating after control, and can even be performed at a low temperature state. The well and the smashing speed can be conducive to retaining biological activity and various nutrients that are not resistant to high temperature. In order to improve the efficacy, such as pearls, use traditional methods to process part of its ingredients, and ultra-micro crushing under low temperature conditions around -67 ° C can be more completely retained with effective ingredients and enhanced its role in delaying aging. Ganoderma lucidum is rich in amino acids and trace elements, which has the functions of activating immune function, antitumor, anti -thrombosis and other effects. After super micro -crushing, the curative effect is more complete;

(3) save raw materials for easy application.

After the traditional Chinese medicine is crushed by super slightly crushing, the small dose can be used to obtain the original prescription effect. Generally, the drugs can be treated after super micro -crushing. Losses, ZUI uses raw materials limited to, so this technology is especially suitable for the crushing of precious and rare Chinese medicines, and due to the increase of fineness, it can improve the sense of sun, which is convenient to take it. It is performed in the systemEffectively avoid external pollution, and control the microorganisms and dust of the product.

3.2 The current status of super microclicage between traditional Chinese medicine is in the study of Liu's Chinese medicine for cell -level micro -crushing. The aforementioned super -micro crushing equipment is exploring and has achieved gratifying progress.

Due to the low production efficiency and long crushing time of the ball mill, it is generally not used in the ultra -micro crushing of Chinese medicine. There are not many reports on the use of Chinese medicine with stirring mills. Nanjing Institute of Technology Jiangsu Super Fine Powder Engineering Technology Research Center has developed an LC -type high -efficiency stirring grinding machine system. The machine is equipped with a special mechanism to prevent the slurry from sinking to the bottom without forming \u0026 quot; dead zone \u0026 quot; The type of shocking crusher conducts cell -level microcomputers on traditional Chinese medicine, especially the crushing of chips and collagen and the dissolution of starch. The impact line speed is about 50 m/s, so if you want to use it, you must be improved. The relatively good units currently doing in this regard are: Wuxi Light Industry University has developed a successful mechanical shear ultra -micro -crushing function to efficiently make fiber granification, successfully use ten soybeans and mung beans to produce. Durezhou Machinery in Zhejiang Province combines high -precision turbine grades with high -speed impact micro -crusher to develop a new generation of high -efficiency and energy -saving CWJ ultra -micro crushing machines. M below. The granularity is not adjusted, and the granularity distribution is narrow. In terms of the research of airflow crusher, the supersonic airflow ultrafine air flow super crushing grading system developed by Nanjing University of Science and Technology Jiangsu Provincial Super Fine Powder Engineering Technology Research Center, integrates multi -inferential technology, fluidized bed technology and lying group points
