Biological, medical sector airflow applications: (1) submicron and nanoscale needles; (2) Medicine refinement, improve absorption (ultra-microcallar); (3) health products refine, improve absorption rate;
my country's crushing machinery is in the 1980s and has been developed later. Due to the extensive industrial production, it has developed rapidly with the rapid development of the national economy. During the research and development of powder production, application and equipment, there are continuous new equipment, new products appear in the market, and the airflow pulverizer is one of many crushing equipment.
The airflow pulverizer is different from other crushers. Under high-speed airflow, the material impacts between the particles through its own particles, the gas stream impacts shear effects and materials and other components. Impact, friction, cutting, smash the material. Therefore, the average particle size of the material after the gas flow is thin, the particle size distribution is narrow, the particle surface is smooth, the particle shape is standardized, the purity is high, the activity is high, and the dispersibility is good; the low melting point and thermal material and biologically active article (because the gas flow is pulverized The machine is powered by compressed air, and the adiabatic expansion of the compressed gas at the nozzle reduces the system temperature). Moreover, when N 2, CO2 is used, the pulverization in the inert atmosphere can be performed. The gas flow is pulverized in a sterile state; the production process is continuous, the production capacity is large, self-controlled, and the automation is high. However, the production cycle of mechanical impact pulverizer, vibration grinding, stirring mill, etc. is often longer, thereby causing low production efficiency; a large amount of heat is generated when the material is pulverized, resulting in deterioration of thermal materials; and equipment wear will contaminate products. . Therefore, these mechanical crushers have not fully satisfied that people have become increasingly high and higher in ultrafine powder, and the airflow crushing equipment has a trend of replacing mechanical pulverities in the production of super fine powder. Since the 1930s, the airflow pulverizer has erected many researchers, and its structure is continuously updated, and the types of species are increasing, and the flat (or disc) airflow mill, circulating airflow pulverizer, hit Airflow pulverizer, fluidized bed airflow pulverizer, target airflow pulverizer, supersonic airflow pulverizer, etc.
There are many types of ultrafine gas flow pulverizer, and the structure is different, and each model has its advantages. In recent years, crushing equipment has been greatly improved in the previous basis, and its structure is constantly improving, and the crushing performance is continuously improved. in order toMeeting information technology, biotechnology and new material technology development on particle size, purity and particle size distribution of powder products, the following aspects should be paid to the following aspects: on the existing basis , Optimize, optimize ultrafine gas flow, develop new equipment, and pay attention to smashing, grading system matching design; large equipment, in the above-mentioned ultrafine airflow pulverizer, compared to fluidized bed hit The airflow pulverizer has a significant advantage, so the theoretical study should be strengthened to guide the design of the pulverization equipment; due to the maximum disadvantage of the gas flow, the energy utilization rate is low, so it should be sought to reduce energy consumption, increase energy utilization. Wait.
Shandong Erfai production gas flow crusher's ultra-fine pulverizer has been more than 20 years, and the gas flow pulverizer produced by high precision, high efficiency and high stability have obtained a large number of faithful users at home and abroad. The old customers' researched rates are high, highlighting Shandong Erman's deep technical heritage and rich success cases are available for reference.
In the past context of economic globalization, more and more foreign exchanges have become an inevitable trend in all walks of life. For AlPa powder, this communication is not only promoted. The exchange of information, and accelerated the pace of ALPA powder into internationalization.
