The requirements of thermal power plant on vertical coal mill

Coal ash currently is one of the most industrial waste in our country. With the continuous development of power plant industry, fly ash emissions from coal-fired power plants are increasing year by year. Therefore, thermal power plant has its environmental protection and energy saving requirements in the processing of coal

Thermal power plant is the use of combustible materials (such as coal) as a fuel to produce electricity in the factory, in order to improve coal combustion efficiency are generally burning coal, so the power plant in the purchase of flour mill, the flammability of the higher requirements of coal . The coal mill is currently used in coal-fired power plant equipment, Chaeng had R & D in the use of special technology and structure, vertical mill noise is only 80-85dB (A sound level), 20-25 lower than the tube mill dB (A sound level). At the same time, the coal vertical mill has no dust flying in the production process and the operating environment is clean. The pulverized coal produced has a fineness of 80 μmR 3%, stable fineness and homogeneous grain size, Grade and excellent combustion performance, fully meet the requirements of power plants

Coal mill structure features:

1, coal vertical mill wheel used in the foot-shaped disc and tire-shaped roller sleeve, more suitable for coal grinding.

2, grinding roller bearings without special seal. Grinding roller device uses a pair of spherical roller bearings, bearing seal cavity extends to the outside of the case, not with dust gas contact, so as long as a simple seal roller bearings can not get into dust, do not need to seal the fan.

3, part of the vertical mill drive, no auxiliary transmission device, green.

4, slag part of the simple. Coal mill less slag, slag discharge port with a cover, do not need to install slag valve.
