Vertical Roller Mill

Vertical Roller Mill

LM series vertical grinding mill is the newest grinding machine, which integrates the advanced international technology and numerous years of mill-producing experience . It is really an ideal equipment that integrates crushing, drying, grinding and grading conveyor all together.
LM series vertical grinding machine could be traditionally used in cement making, power , metallurgy, chemical and non- metalliferous ore industries. It is used to grind lumpy, granular and powdery materials to the required size.

Features and Benefits

The whole plant is really a vertical structure of strong systematic characteristic, so that it occupies small area. From crushing of raw material to grinding and packing is definitely an independent production system. Compared with other milling plants, its passing ratio achieves 99%, itrrrs this that other mill cannot reach. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably. The electrical control system is centralized controlled, so the automaticity is high, no individuals are necessary for the operating room.

Working Principle

The motor drives the grinding table through decelerator. Materials collapse the center of grinding table from feed opening. At the same time, hot air makes the mill in the air inlet. As a result of centrifugal force, materials go on to the advantage from the grinding table. The materials are pulverized from the roller when by pass of the groove about the grinding table. The crushed materials are brought up by vane high-speed airstream, the more expensive particles collapse to the grinding table for regrinding. Once the materials in the airstream pass the separator on the top of the mill , the coarse powder collapse the grinding table for regrinding under the function of rotation rotor. The fine powder happens with the airstream , and it is gathered by the dust catcher. The materials pleased with moisture will be dried once they satisfy the hot airstream. Through adjusting the temperature with the hot airstream, it could meet different material’s requirement, and also through adjusting separator , it may reach proper fineness of materials.
