Vertical Roller Grinding Mill In Thermal Power Plant

Vertical Roller Grinding Mill / Vertical Mill Prices In Thermal Power Plant

Description

Coal vertical mill, also known as coal mill and coal mill, is specialized in ultra-fine grinding of raw coal and bituminous coal in cement, power plant, steel plant and other fields. HVM coal vertical mill produced by Hefei Hengcheng adopts special structure design and production process, which is energy-saving and environmental friendly.

[Capacity] 10-90t/h
[Fineness of Finished Product] 80 μ mR 3%
[Power of main motor] 110-1120kw
[Application field] Cement plants, lime plants and other coal grinding enterprises

Product advantages:
1. Large production capacity, low energy consumption, and environmental protection.
2. The roll sleeve can be turned over for use, which is not only conducive to improving the output of the coal mill, but also can reduce wear and prolong its service life.
3. Install explosion-proof devices to ensure safe production. The upper shell is equipped with an explosion-proof valve to prevent the explosion of pulverized coal in the mill and ensure the safe use of the equipment.

Technical DATA

Working Principle:

In the process of pulverized coal production, the main motor drives the grinding plate to rotate through the reducer, while the hot air enters the vertical mill from the air inlet, and the raw coal falls to the center of the grinding plate through the blanking pipe. The grinding plate that rotates at a constant speed disperses and flattens the raw coal outward with the help of centrifugal force, so as to form a bed with a certain thickness. The raw coal is rolled and crushed by several grinding rollers on the grinding plate at the same time. Under the continuous drive of centrifugal force, the raw coal continuously moves towards the outer edge of the grinding plate. When the powder leaving the grinding plate meets the hot gas entering the mill through the wind ring and rises, it enters the separator through the middle shell of the mill. During this process, the pulverized coal and the hot gas have sufficient heat exchange, and the water is rapidly evaporated. The powder concentrator controls the particle size of finished products at the outlet of the roller mill. Particles larger than the specified size are separated and returned to the grinding plate. The pulverized coal meeting the fineness requirements enters the dust collector through the powder concentrator, and the collected finished products are sent to the finished product bin.
