Vertical roller mill
Vertical Roller Mill is a new kind of large-scale grinding mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With decades of years’ research, Vertical Roller Mill is designed and manufactured based on our advanced design idea.Now it has found its extensive application in the mining ,chemistry, non-metallurgy and other hundreds of industries.
Working Principle
1)The motor dives the grinding table to turn through the speed reducer. At the same time, hot air comes into the roller mill from the air inlet. The materials fall down the centre of grinding table from the feeder.
2)Because of the centrifugal force, the materials move to the edge of grinding table from the centre
3).The materials are crushed by the grinding roller when they passes the groove on the grinding table. The crusher 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. 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)The time materials stayin the machine body is short ,which can reduce the repeating grinding and have a stable quality.
2)the adjustable dry air temoeture,and high drying ability ,energy-saving
3)the non-direct contacting equipment installed on the roller shells and the grinding liner can avoid the damage compact and strong shaking.
4)the machine merges the crushing ,drying,grinding ,and classifying into a single whole .
5) the grinding roller and the liner adopts the high-quality materials ,which can reduce the abrasion and increase the service life .
6)the whole seal of the equipment makes the system work in a negative environment with no dust leaking and a clean environment.
Main Structures
It mainly consists of : powder-collector,grinding roller ,pressure equipment,grinding plate ,decelerator,electric motor,and and the machine shell ,etc.
