Coal Mill in Power Plant

Mill Plant Introduction:
The mill plant is widely used in metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing. According to the fineness of the grinding of materials and discharging materials fineness, milling machines can be divided into Raymond Mill, vertical pendulum mill, high pressure hanging roller mill, high pressure micro powder mill, Straight Centrifugal Grinder machine, super pressure trapezium mill, three-ring medium speed mill six mill type.
Coal Mill in Power Plant:
Power plant, in order to achieve the best efficiency of coal combustion, coal processing for the pulverized coal, then burning. This coal combustion more fully in the power generation process, he can achieve the highest thermal energy conversion rate.
The wind swept coal mill has been widely used in thermal power plants at home and abroad, but its pulverizing system of high energy consumption, high power consumption is about 20% of the electricity plant. Equipment has been finalized and put into operation in pulverizing system, to reduce the milling power consumption, must try to maintain the coal mill for optimum operating conditions. As the coal mill is a nonlinear, large delay and uncertainty of the disturbance variable objects required to run to achieve the the pulverizers best conditions difficult to achieve during the operation.
Speed coal mill power plants must achieve lasting performance for a major overhaul in 3-7 years time, which is crucial for the entire power plant. Therefore, the grinding of pulverized coal in the difficult task, should be tested to prove and with full design speed coal mill power plants to bear.
Speed coal mill design the power plant has two main parts:
1, Grinding the processing related to the wear and tear parts, spring pressure, rotational speed, transmission (including the proper design of the gearbox and motor). Gear machine and its components must be designed to have a higher discretionary working life, in order to ensure continuous work throughout the plant life midterm.
2, Drying and separation characteristics, we must rely on the throat cross-sectional area, housing and separation of pulverized coal meal separator volume to achieve.
Therefore, the power plant coal mill can generally choose the vertical coal mill, medium-speed coal mill, or the European version of the trapezoidal coal pulverizer.
