Different machines to meet all needs
The fine performance of coal mill is essential for better combustion. Coal gets ground by grinding elements in stages. Hot primary air from air pre heater drives moisture from coal and acts as carrier to transport pulverized coal to the boiler through pipes.

Abstract: This paper presents a segment coal mill model that covers the whole milling process from mill startup to shutdown. This segment mathematical model is derived through analysis of energy transferring, heat exchange, and mass flow balances. The work presented in the paper focuses on modeling E-type vertical spindle coal mills that are widely used in coal-fired power plants.

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.

Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 degree centigrade, the upper limit is ...
