The basic principle, advantages and disadvantages of air jet mill
Airflow mill is a powder preparation technology that uses high-speed airflow to collide and grind materials. Its basic principle is to feed the material into the airflow mill. Then the material are dispersed, ground and mixed the material through the impact and shear force of high-speed gas. Thus we can obtain the powder as required. Compared with the traditional mechanical grinding method, the airflow mill has the following advantages:
- ① Uniform particle size distribution: During the grinding process , the material is impacted and sheared by the high-speed airflow. Particles collide and rub against each other in the process. This ensures a more consistent particle size distribution.
- ② High powder quality: During the grinding process, forces applied to materials are more uniform. It is not easy to produce excessive wear and heat loss, thereby obtaining a higher quality powder.
- ③ High production efficiency: The airflow mill has high production efficiency, high degree of automation and low energy consumption.
However, the airflow mill also has some shortcomings, high gas consumption and significant noise issues. Therefore, these problems need to be paid attention to in practical applications.
