Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum.

The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal plays an important role in the manufacturing process of cement. Based on the composition of raw feed a wide range of coal is used. In a cement plant two systems of coal firing are used, namely, a) Direct firing and b) Indirect firing.
schematic figure of coal mill in a cement plant Parametric Studies Of Cement Production Processes The cement production in the MCC plant is based on the dry process technology, and according to the preliminary energy audit, the thermal energy consumption in MCC is about 3.5 GJ per ton of produced clinker.
As shown in Tables 1-4, the fault-prone components on these units are the gears, bearings, couplings, shafts, impeller/blades and electric motor. Figures 3 and 4 respectively show the schematic and pictorial representations (with the positions of the various VCM sensors) of the coal mill main drive assembly, bag house fan and booster fan.
In the cement manufacturing process, most material must be broken, such as limestone, iron ore, clay and coal etc. Limestone is the main raw material for cement production, each producing a ton of clinker needs about 1.3 tons of limestone, more than 80% of raw material is limestone.
To support the production of cement, the plant has modern vertical roller grinding mills along with tube mills both for raw meal as well as coal. Cement grinding is achieved exclusively by tube mills/horizontal ball mills. The final products of the plant include PPC, OPC, PSG and other special cements.

The cement production in the MCC plant is based on the dry process technology, and according to the preliminary energy audit, the thermal energy consumption in MCC is about 3.5 GJ per ton of produced clinker. The main source of energy in the plant is the coal that is obtained from Tanzania (Tancoal) and from Malawi (both, Mchenga and Erland).

FIGURE 7-2. Coal production and consumption in the U.S. in the past 150 years. [Source: Energy Information Administration.] Coal Formation As described in the general discussion of the carbon cycle (Chapter 6), coal was formed from prehistoric plants, in marshy environments, some tens or hundreds of millions of years ago.
Coal mills use air to fluidize the coal after grinding and to evaporate any moisture. If hot air, either from the cooler or pre-heater, is used then external air is mixed in to control the inlet ...

The cement manufacturing process starts with the mining of limestone that is excavated from open cast mines. Then this limestone is crushed to -80 mm size and is loaded in longitudinal stockpiles. Limestone is taken out diagonally from these stockpiles for grinding in raw mill hoppers. As mentioned earlier coal is used as a fuel to heat the raw ...
