Air Classifying Mill
The material is uniformly sent into the grinding chamber by the feeding system, and is strongly impacted by the high-speed rotating grinding disc. At the same time, it is subjected to the centrifugal force to collide with the crushing ring gear, and is subjected to various comprehensive forces such as shearing, friction, and collision. The material is ground, and the crushed material moves to the classification area with the airflow. The coarse and fine materials are separated through the classification wheel adjusted by the frequency conversion.
Working Principle
The material is uniformly sent into the grinding chamber by the feeding system, and is strongly impacted by the high-speed rotating grinding disc. At the same time, it is subjected to the centrifugal force to collide with the crushing ring gear, and is subjected to various comprehensive forces such as shearing, friction, and collision. The material is ground, and the crushed material moves to the classification area with the airflow. The coarse and fine materials are separated through the classification wheel adjusted by the frequency conversion. The products that meet the fineness requirements enter the cyclone collector and the dust collector with the airflow for collection, and the coarse particles return to the grinding area to continue shattered.
Features And Benefits
- Integration of grinding and classifying, classifying wheel is adjusted to obtain ideal particle, and the classifying rotor can be installed horizontally or vertically.
- Different types of grinding disc are used based on characteristics of materials to obtain different grinding forces and improve grinding efficiency.
- Key parts are made of ceramic, ensuring non-contact with metal throughout the grinding for high purity of the final product.
- It can produce products with multiple particle sizes at one time; grinding is in closed system, low dust and noise, clean and environmentally friendly production process.
