Industry analysts said that with the advancement of scientific and technological progress, manufacturing process improvement, my country's market on micro-powder and ultrafine powder is continuously improved, and the importance of gas flow grinding is increasingly prominent. The downstream application is constantly Expansion, the industry has a good prospect. At the same time, the application of high-performance materials and new materials has also made my country's market automation, intelligence, and high precision requirements in China, and upgrades to high-tech content to the inevitable trend of my country's gas flow grinding industry.Airflow ultrafine pulverizer is routinely at the end of product production, the performance of finished products is very affected, so it is an important part of powder processing materials. Many powder materials are very expensive, such as diamonds, battery materials, etc. If the product is unqualified or pulverized, the yield is greatly reduced, and the loss is very large, so the airflow ultrafine pulverizer can produce a narrow particle size However, it is very important that there is no fine particles. When the basic function is determined, it is proposed that the pulverization is proposed. Whether the pulverization requirements are met, the air flow ultrafine pulverizer is ultrafine pulverized equipment, not nano-crushing equipment, 200 nm or less, it is difficult to reach nano-level . Performance parameters are D97 = 2-74 um, that is, the fineness can be 97% = 2um, if it is 50% or average particle size, at 0.5-1 um, such performance is the limit of the device, and is for some comparison Special materials, not all materials can reach this requirement, so the airflow ultrafine pulverizer is not reached by nanometers.
The initial fineness of the raw material is related to the physical properties of the material, and the fluidity in the material is related to the uniformity of particles. Some materials are fluidity, high impurities, high solvent content, can be blocked in the production process, this time you need to use special equipment, not all materials can be pulverized with standard equipment can achieve crushing fineness. It is related to the pulverization pressure during the pulverization process, and some of the equipment feed pressure is greater than the pulverization pressure, and some equipment is larger than the feed pressure, and the particular material needs to be specifically designed. There is a relationship with the feed speed, not all material fluidity is very good, whether it is a screw feeding or a vibration feed, the feed process is a very important factor, some of which is very fine, this It is necessary to reach the feed effect with a dedicated personalized configuration. So for some kind of material ZUIA good way is to first do a test to see the effect, don't take any fineness of a certain machine, the same machine is smashing other materials may reach D100 <2微米，但是对另外一种物料可能d90<5微米也达不到。
final, air flow ultrasound The pulverizer is a fine device that is generous in the physical crushing, but is limited to micron levels. So far, the physical crushing equipment is not reached the nano-stage fineness. Moreover, the selection of airflow ultrafine pulverizer is also very strict requirements. Next article Let's talk about the requirements of the gas flow ultrafine pulverizer for materials.
ALPA powder technology has always adhered to the development concept of "we use the heart, only the airflow mill", adhering to the "quality first, service-oriented" concept, has been based on technological innovation, science and technology research and development As the cornerstone, constantly improve the efficiency and safety of the airflow pulverizer, and is committed to providing customers with safer, energy-saving, environmentally friendly airflow mill products, creating more value for customers, creating greater benefits for employees, for society Do more responsibility.
