Scope of use of medium speed coal mill in power plant

In our country, the total social electricity consumption from January to November 2022 totaled 7,858.8 billion kilowatt-hours, an increase of 3.5% year-on-year. Talking about electricity consumption, at present, our power supply is dominated by thermal power generation (more than 70%). Thermal power plants are categorized into coal-fired power plants and gas-fired power plants according to the different combustion methods. Coal-fired power plants, in order to improve the efficiency of coal combustion, need to first process the lump coal into coal dust.

Coal mill, as the name suggests, is the equipment that grinds coal into powder, and it is also an important auxiliary equipment for full combustion of pulverized coal furnace. Medium-speed coal mill refers to the coal mill with the working speed of 50~300r/min, which belongs to the specialized equipment for coal powder processing. It is suitable for powder grinding operation of medium hardness raw coal such as bituminous coal and poor coal, especially for blast furnace coal injection powder making system.

Medium-speed coal mill used in China are flat disk mill, bowl mill, ball mill, ring roller mill, etc. Different forms of medium-speed coal mill are used in different situations. Various types of coal mills have their own advantages and disadvantages and scope of adaptation. Medium-speed coal mill coal powder uniformity is very good, the initial investment is small, the operation of the power consumption is small, compact structure, small footprint, can be widely used in electric power, metallurgy, building materials, chemical industry and other industries of the powder system.

Power plant coal-fired furnace coal mill selection comprehensive consideration of various factors. For example, the type of coal, investment budget, layout and installation conditions, as well as the reliability of equipment operation, economy, such as powder production power consumption, metal material consumption and maintenance of labor consumption and other specific realities.
