The development of the crushing airflow began with Guslin, and has experienced the success of Andrew's flat airflow crusher. It has developed for about 100 years. type. There are advantages and disadvantages. In comparison, the fluidized bed -type air crusher has obvious advantages and represents the mainstream direction of the development of air flow crushing equipment.
At present, the development and production of my country's ultra -fine airflow crushing equipment has been greatly developed, which has made important contributions to my country's powder industry. However, there is still a large gap compared with developed countries. It is mainly manifested that there are fewer models of independent innovation. Most manufacturers still stay at the stage of imitation foreign products; There are few products. The airflow crusher is one of the important equipment for ultra -micro processing. The airflow crusher, also known as the airflow crusher, refers to the use of high -speed airflow (300-500m/s) or overheating steam (300-400 ° C) energy Shocking, collision, friction to achieve ultra -fine crushing equipment. Compared with other types of crusher, the air flow crusher has the following advantages: ① the product has good granularity. The average granularity (D50) of the material is generally below 5 \u0026 mu, and the particle size is narrow. ② High product purity, especially suitable for the crushing of materials that are not allowed to be contaminated. ③ Crossing low melting points and thermal materials. ④ The product has high granular activity and good decentralization. ⑤ The production process is continuous, the production capacity is large, and the degree of automation is high.
