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.
Next, in November 2014, Titan Cement ordered a Gebr. Pfeiffer SE type MPS 2800 BK vertical roller mill for coal grinding, to be set up at line 1 at its Beni Suef plant. In January 2015, Suez Cement, Italcementi's Egyptian arm, said that it would spend US$84m during the year to convert its Helwan and Tourah 2 cement plants to use coal.

Aug 30, 2012· This saves the extra fuel cost and makes cement somehow economical. Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite.
Coal Mills for Cement Plants. Coal grinding mills ... (for replacing grinding parts) into consideration. Mill sizes are identified according to the outer effective diameter of the grinding track in decimetres [dm]. The identification is followed by a digit, separated by a full stop. This specifies the number of rollers operated in the mill.
Cement grinding. The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).
