Air Classifier Mill MJL-W

MJL-W air classifier mill is driven independently by the crushing disc and the classifying wheel, the crushing disc is installed vertically, and the classifying 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 causes the material to be ground. 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

Double-sided hammer head structure design improves grinding efficiency.
Special feeding method, convenient for forced grinding.
External bearing, good heat dissipation, natural cooling or water cooling.
The structure of the side opening door is convenient for manual maintenance and cleaning.
Provide different construction materials according to different project needs, such as carbon steel, stainless steel, wear-resistant steel, and ceramic lining.
The overall steel structure base is conducive to the stable operation of the equipment.

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.
