With the rapid development of ultrafine powder related industries, it is widely used in fluid bed gas flow grinding in various industries due to their special performance, and it will become an important member of non-metallic industrial machinery. And key research direction.
The development of gas flow begins with Goslin, experienced the success of Andrew's flat airflow pulverizer, developed about one hundred years, the development of technology has been mature, forming five stable five kinds of stable Typical models. It has its own advantages and disadvantages. Compared to comparison, the fluidized bed airflow pulverizer has a significant advantage, representing the mainstream direction of the development of the gas flow crushing equipment.
At present, the development and production of ultrafine gas flow crushing equipment in my country has been greatly developed, and it has made important contributions to my country's powder industry, but it still exists than developed countries. Small gaps, mainly, independent innovation models, most manufacturers also stay in the stage of imitation of similar products; large, specialization, can produce high purity, high fine products.Airflow pulverizer is one of the important equipment for ultra-fine processing, and the airflow pulverizer is also known as the airflow pulverizer refers to the energy of high-speed airflow (300 ~ 500m / s) or overheating steam (300 ~ 400 ° C). Implement the particles to impact, collide, and friction to achieve ultrafine pulverized equipment.
The airflow pulverizer has the following advantages over other types of crushers: 1 Good product particle size. The average particle size (D50) of the material is typically 5 μm or less, and the particle size distribution is narrow. 2 High purity is high, especially for drugs such as drugs and other materials that are contaminated. 3 can be pulverized with low melting points and thermal materials. 4 The product is highly granulated and has good dispersibility. 5 Continuous production process, high production capacity and high automation.
