By the adoption of advanced technology from home and abroad ,and years' production experience , the vertical roller mill is developed to be a kind of advanced grinding mill equipment. It mainly consists of:classifier,grinding roller ,pressure equipment,grinding plate ,decelerator,electric motor,and and the machine shell ,etc.And it merges the dry,powder grinding,classifier,and promotion into a single whole .
Working Principle:
1)The motor dives the grinding table to turn around through the decelerator. At the same time, hot air flows into the roller mill from the air inlet. The materials fall down on the centre of grinding table from the feeder.
2)Because of the centrifugal force, the materials will move to the edge of grinding plate from the centre .The materials are crushed by the grinding roller when they passes the groove on the grinding table. The crushed materials continue to move to the edge of the grinding table until they are taken away by the airstream. Then the bigger materials fall down the grinding table and the process of crushing continues.
3)When the materials in the airstream pass the separator on the top of the mill, the materials fall down the grinding table from the taper filler under the force of guide leaf blade. The fine powder comes out with the airstream, and is gathered by the dust catcher of the system. The powder gathered is the final product of roller mill.
4) In the process of the contact of airstream , the materials are dried to meet the clients' need at the proper moisture. Through the adjustment 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 the separator rotor, it can reach the proper fineness of the materials.

Technical advantages:
1. low operation cost
(1)High–efficient :the materials will be crushed directly on the plate by the roller so that its energy consumption is very low.Compared with the ball mill system ,it can save energy by 30%~40%.
(2)Low wearing parts :As the no direct contact between roller and plate ,and the adoption of the high-quality materials ,so its service life is long and low wearing .
2.powerful dry system
As the direct contact between the materials and the hot wind in the grinding mill ,it features powerful dry system ,energy-saving. And it can also meet the various requirements of the materials with various range of humidity.
3.Reliable function
(1)Equiped with the automatic contralling equipment ,it has realized the romote control ,which makes a convenient operation.
(2)The roller selleve and plate are easy to change in a short time by fixing the oil tank and turning around the flexible arms.
Envionment-friendly ,energy-saving :slight vibration , low noise and dust ;clean working condition
