Summary of Coal Mill Controls. 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 ...
Airswept coal mill is the main equipment of cement plant, also called coal mill in cement plant, used for grinding and drying various hardness of coal, crushing the coal briquette into pulverized is the important auxiliary equipment of pulverized coal furnace. The airswept coal mill runs reliably, can work continuously, also has a large production capacity and less energy consumption.

The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.
