Structure and Principle of Super Fine Vertical Mill

The ultra-fine Vertical Roller Mill Production Process is mainly composed of the main machine, feeder, classifier, blower, pipeline device, storage hopper, electrical control system, and collection system. The motor drives the reducer to drive the grinding disc to rotate. The material to be grounded is fed into the center of the rotating grinding disc by the feed lock device.

Under the action of centrifugal force, the material moves to the periphery of the grinding disc and enters the grinding roller table. Under the action of the roller pressure, the material is crushed by extrusion, grinding and shearing. At the same time, the wind is sprayed upward uniformly from the wind ring around the grinding disc, and the ground material is blown up by the high-speed air flow at the wind ring, and the coarse-grained material is blown back to the grinding disc for re-grinding. The classification machine performs the classification, and the qualified fine powder goes out with the airflow and is collected by the dust collection equipment to be the product. The unqualified coarse powder falls to the grinding disc under the action of the blade of the classification machine, and is reground together with the newly fed material. In this way, the whole process of grinding operation is completed.

When the iron and other impurities mixed with the material move to the edge of the grinding disc with the material, due to its heavy weight, it cannot be blown up by the wind. The rotor speed of the multi-head classifier is easy to adjust, and a variety of qualified products can be obtained.
