Coal Mill in Cement Plant Vertical Roller Mill Air . The most used coal mills in cement plants are airswept ball mill and vertical roller mill At present, most cement plants use coal as the main fuel in the clinker production process The standard coal consumed by the new dry process for producing 1 ton of cement clinker is usually between 100 kg and 130 kg, and the fuel cost accounts for about.Coal fines are usually prepared by air swept coal mill or vertical mill. In order to produce high-quality 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.
Coal Mill Coal is still used in approximately 90 of cement plants globally to deliver the energy needed for the heat inside the kiln. Online coal analyzers using PGNAA technology are used to control the coal blend to a specific GCV in addition to the ash value of the coal as this adds raw materials to the process as well.
