Coal Vertical Roller Mill

Burning coal powder is an important means for large coal vertical roller mill to improve coal-fired efficiency, so the role of coal vertical mills in general power plants is very import.

Coal vertical roller mill is mainly to send the raw coal in the coal hopper of the coal vertical roller mill for grinding into pulverized coal, and then the pulverized coal is blown into the powder discharging fan by the hot air, and then enters the furnace of the boiler. Internal combustion, this is the general working principle of the coal vertical roller mill.

Coal Vertical Roller Mill

The coal vertical roller mill structure is an important guarantee for the full combustion of coal powder in power generation, so the coal vertical roller mill structure is especially critical. Generally, the rotational speed of coal vertical mills in power plants is generally around 40~300r/min, and the compact structure is small, and the operation is lighter and more energy-saving and environmentally friendly. It is one of the most widely used machines in thermal power plants.

In the coal-fired power plant of the thermal power plant, the coal vertical roller mill is a very important basic equipment. The safety and stability of its operation are directly related to the overall work of the entire thermal power generating unit, so the coal vertical roller mill of the power plant is Quality testing must be carried out before use, which is verified during the load trial operation and can achieve the quality of “testing without watts”. The grinding efficiency and fineness of the coal vertical roller mill have a good guarantee, so it is easier to fully burn the coal powder in the boiler, and it can also improve the utilization of coal powder and reduce the possibility of environmental pollution.
