SBM LM Series High Quality and Large Capacity Vertical Mill

LM Vertical Grinding Mills Product Introduction

By bringing in the European advanced technology anddecades of years’ research, Vertical Roller Mill is developed to be a new kindof large-scale grinding mill, which has solved some technical problems, such aslow capacity and high consumption in the industry mills. With the reasonable structuredesign and advanced process flow,it merges the dry, powder grinding, classifier, and promotion into a singlewhole. Especially in the large-scale grindingcrafts, it totally meets the requirements of the clients, and its maintechnology and economic index have reached the international advanced level.

LM Vertical Grinding Mills WorkingPrinciple

1. The motor dives the grinding table to turn aroundthrough the decelerator. At the same time, hot air flows into the roller millfrom the air inlet. The materials fall down on the center of grinding tablefrom the feeder.

2. Because of the centrifugal force, the materialswill move to the edge of grinding plate from the center. The materials arecrushed by the grinding roller when they pass the groove on the grinding table.The crushed materials continue to move to the edge of the grinding table untilthey are taken away by the airstream. Then the bigger materials fall down thegrinding table and the process of crushing continues.

3. When the materials in the airstream pass the separatoron the top of the mill, the materials fall down the grinding table from thetaper filler under the force of guide leaf blade. The fine powder comes outwith the airstream, and is gathered by the dust catcher of the system. Thepowder gathered is the final product of roller mill.

4. In the process of the contact of airstream, thematerials are dried to meet the clients’ need at the proper moisture.Through theadjustment of the angle between the separator and the leaf of wind’s direction(not suitable to the small type of vertical mill), and also the speed of theseparator rotor, it can reach the proper fineness of the materials.
