To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

Results from this testing illustrates large fineness deviations from pipe to pipe. Non Isokinetic testing or not sampling all fuel lines can lead to unrepresentative results. All coal pipes from a single pulverizer will usually have varied fuel fineness. Sometimes, widely varied. Testing all pipes is recommended.
This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coalfired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
The coal mill can also grind petroleum coke and anthracite down to a fineness below 5% +90 micromillimeters (mm) when coupled with a variable speed mill motor. No sticky situations The ATOX® Coal Mill can grind and dry raw coal with up to 25 percent moisture level.

Coal Vertical Mill is a mechanical device used to pulverize coal for combustion in the steamgenerating furnaces of fossil fuel power plants. Coal pulverized machine is the ideal powder making equipment in electric power industry, metallurgy industry, chemical industry, building construction, coal industry, fireproofing materials making industry and some others.
A highquality coal mill can effectively solve the fineness problem of coal powder and ensure uniform grinding of raw coal. The fineness of pulverized coal has a great influence on the ignition temperature and burning time of the equipment. In this way, the influence of bad raw coal on combustion efficiency can be well improved by coal mill.
Coal mill is the equipment used for grinding and drying coal with different hardness and it is mainly composed of feeding device, principal axis, rotating the part, transmission part, discharging part, highpressure starting device, and lubrication system. It is widely used cement, building material, thermal power generation, metallurgy, and chemical industry.
