With the continuous development of power plant industry, fly ash emissions from coal-fired power plants are increasing year by year. Therefore, in actual production, thermal power plants in the processing of coal, its environmental protection and energy saving requirements.
Coal ash is currently one of the mostindustrial waste in our country. With the continuous development of power plantindustry, fly ash emissions from coal-fired power plants are increasing year by year. Therefore, in actual production, thermal power plants in the processing of coal, its environmental protection and energy saving requirements.
Thermal power plant is the use ofcombustible materials (such as coal) as a fuel to produce electricity in thefactory, in order to improve coal combustion efficiency are generally burningcoal, so the power plant in the purchase of flour mill, the flammability of thehigher requirements of coal . The coal mill is currently used in coal-firedpower plant equipment, ZK CORP in the development of a special process andstructure, vertical mill noise is only 80-85dB (A sound level), 20 ~ 25 dB (Asound level). At the same time, the coal vertical mill has no dust flying inthe production process and the operation environment is clean. The fine coalpowder produced can reach 80μmR3% fineness, stable fineness and uniformgranularity, with the excellent combustion performance, fully meet therequirements of power plants.
Coal vertical mills structure features:
1. Coal vertical grinding wheel used in thefoot-shaped disc and tire-shaped roller sleeve, more suitable for coalgrinding.
2. Grinding roller bearings without specialseal. Grinding roller device uses a pair of spherical roller bearings, bearingseal cavity extends to the outside of the case, not with dust gas contact, soas long as a simple seal roller bearings cannot get into dust, do not need toseal the fan.
3. Part of the mill drive, no auxiliarytransmission device, green.
4. Slag part of the simple. Coal verticalmills less slag, slag discharge port with a cover, do not need to install slagvalve.
