Vertical Roller Grinder Structure:

LM Series Vertical mill (roller mill) is mainly from the separator, roller device, disc device, pressure device, reducer, motor, housing and other components. Separator is an efficient, energy-efficient separator device. Roller for rolling the material is used to crush the parts. Disc fixed to the reducer output shaft is the place where roller compacted material. Pressure device is provided for the grinding pressure roller components, to provide sufficient pressure roller to crush material.

Vertical Grinder Features:

• 1. Grinding efficiency, operating costs: vertical mill grinding using principle of grinding the material layer materials, low energy consumption, grinding system and lower power consumption than the ball 20 to 30%, and with the increase of raw materials, water, energy-saving effect is more Significant;
• 2. Construction, investment, low cost, no other set drying, the powder, and other equipment to enhance;
• 3. Run easy, reliable, easy operation and maintenance, is equipped with automatic control device, which enables remote control, easy to operate;
• 4. Equipment drying capacity, grinding materials widely;
• 5. Product quality and uniformity of particle size distribution;
• 6. Equipment, environmental protection, low noise, low dust, clean operating environment.

Vertical Grinder Working Principle:

Disc drive motor through reducer rotating air lock feeder through the material feed port fell from the central disc, while hot air from the air inlet into the mill. With the disc's rotation, the material under the action of centrifugal force to the disc edge and moved across the disc when the annular groove on the roller by rolling and grinding, grinding the material in the disc after the edge of high-speed air ring with the wind, the large Straight into the disc particles to re-grinding, air flow through the upper part of separator material, the effect of the rotating rotor, meals bucket fell from the cone disc re-grinding, qualified with a grinding powder with the air flow through the income Dust collection devices, that is, products, materials containing water contact with the hot air drying process is, by adjusting the air temperature, humidity materials to meet different requirements, meet the requirements of the product water. By adjusting the separation can be achieved by the required granularity of different products.
