Airflow pulverizer is a kind of equipment commonly used for material refinement and grinding, and is widely used in chemical, pharmaceutical, food, metallurgy, mining and other industries. Its core working principle is to use high-speed airflow to impact, shear and rub the material to achieve the effect of crushing.
Jet Mill Composition
The airflow pulverizer has five parts: a feeding system, a crushing chamber, a compressed gas system, a classification system, and a collection system.
1. Feeding system: It usually has a hopper and a feeder. It feeds the material to be crushed into the crushing chamber evenly and stably.
2. Crushing chamber: It is the core of the airflow pulverizer. It holds nozzles and grinding rings. The nozzle sprays compressed gas at high speed to create a strong airflow. The grinding ring then further grinds and crushes the material.
3. Compressed gas system: It powers the airflow pulverizer. It is usually made of an air compressor, air storage tank, and air filter. These ensure the airflow to the crushing chamber is clean, stable, and continuous.
4. Classification system: It separates materials of different particle sizes by adjusting the airflow. It changes both the speed and direction. The grading system usually has a cyclone separator and a grading screen. They can effectively sort the crushed materials by size.
5. Collection system: responsible for collecting the graded materials. It usually includes bags, collectors, and other equipment. They ensure safe, easy collection and storage of materials.
The airflow pulverizer has three main advantages. It is efficient, produces a uniform particle size, and causes no pollution. At the same time, it is easy to operate and maintain, and can adapt to the crushing needs of different materials. However, the airflow pulverizer has downsides. It consumes a lot of energy and is very loud. These issues need to be addressed in real-world use.
In short, the airflow pulverizer is an efficient, practical crusher. Its structure and working principle are simple and clear. In practice, only reasonable selection and adjustment can achieve a good crush. This must match the material’s properties and the crushing requirements. Also, we must maintain the equipment. This ensures its stable, long-term operation and extends its life.
