Get PriceIn order to reduce energy consumption and ensure the quality of cement clinker burning, its necessary to explore new optimal control methods to stabilize the temperature of rotary kiln.
Get PriceClinkers form in coalfired boilers when the fuel source used to power the boiler is inferior. poorquality coal contains more water and minerals. these compounds break down when heated to high temperatures, and the debris that results clings to the sides or floor of the boiler, where ash can cover it.
Get PriceCoal fines are usually prepared by air swept coal mill or vertical mill. in order to produce highquality clinker, the fineness of coal fines should be controlled at about 12, and its moisture content should be controlled within 1.0. the machines that are usually used to dry the coal fines are rotary dryers.
