Air Classifier Mill MJW-W

MJW-W air classifier mill is driven independently by the horizontal crushing disc and the classifying wheel, and the classification wheel is installed horizontally. The material is evenly fed into the grinding chamber by the feeding system, and is strongly impacted by the high-speed rotating crushing disc, and at the same time, it is subjected to centrifugal force and collides with the crushing ring gear. The comprehensive effect of various forces such as impact, shear, friction, and collision to make materials into powder. The ground material moves to the classification area with the airflow, and the coarse and fine materials are separated by the frequency conversion regulated classification wheel. The fine powder products that meet the fineness requirements are brought into the cyclone and dust collector by the airflow, and the coarse materials are returned to the grinding area for re-grinding.

Product features

Horizontal classification design, more suitable for ultra-fine powder production, performance comparable to German ZPS air classification mill.
The unique grinding structure and classofying structure design realize the unique grinding effect.
Special flow field design to avoid the accumulation of some materials with poor fluidity.
The classifying apex cutting is more precise and the particle size distribution of the product is narrower.
Easy to clean, suitable for the production needs of frequent replacement of materials.

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.
