LM Series Vertical Mill is produced by Henan Liming Road and Bridge Hevey Industry Co.Ltd.It can be widely used in such industries as cement, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.How does LM Series Vertical Mill crush the different kinds of stone ? If you want to know this,please see the working principle of LM Series Vertical Mill.

The Working Principle of LM Series Vertical Mill :
Motor runs under the condition that speed reducer drives the Nether millstone.The matericals fall into the center of device through lock air feeder,and not hot air comes into mill through air inlet.Under the function of centrifugal force,the materials move to the edge of the Nether millstone as it runs and rollers will grind the materials when they come by the annular chute.The grinded materials will be taken up by air circulation and the bigger powders will fall down for regrinding . Qualified powders will be collected by collecting device as to be final product.Materials containing water will be dried when they contact with the hot air.Different dumidity materials can be dried to the requirement through adjusting the temperature of hot air.Adjusting the separator can get the required fineness powders.
