CSM-VD Impact Mill(Air Classifying Mill)

The materials are evenly sent into the crushing chamber by the feeding system, and are strongly impacted by the high-speed rotating crushing disc. At the same time, they are impacted by the centrifugal force, collide with the crushing gear ring, and are subjected to a variety of comprehensive forces such as shear, friction and collision, so that the materials are crushed. The crushed materials move to the classification area with the air flow, and the coarse and fine materials are separated by the classification wheel with frequency conversion adjustment, The products meeting the fineness requirements enter the cyclone collector and dust collector with the air flow for collection, and the coarse particles return to the crushing area for further crushing.

Product Description

The materials are evenly sent into the crushing chamber by the feeding system, and are strongly impacted by the high-speed rotating crushing disc. At the same time, they are impacted by the centrifugal force, collide with the crushing gear ring, and are subjected to a variety of comprehensive forces such as shear, friction and collision, so that the materials are crushed. The crushed materials move to the classification area with the air flow, and the coarse and fine materials are separated by the classification wheel with frequency conversion adjustment, The products meeting the fineness requirements enter the cyclone collector and dust collector with the air flow for collection, and the coarse particles return to the crushing area for further crushing.

Working principle

The material is evenly fed into the grinding chamber by the feeding system, strongly impacted by the high-speed rotating grinding disc. At the same time, it is subjected to centrifugal force and collides with the grinding ring gear, and is subjected to various comprehensive forces such as shearing, friction and collision to finished grinding. The grinded material moves to the classifying zone with the airflow. The classifier is adjusted by frequency conversion, separates the coarse and fine materials, the product that meet the fineness requirement enters the cyclone collector and the dust collector with the airflow, and the coarse powders return to the classifying zone, secondary grinding.
