Cement plants need electric power to operate clinker mills. Egypt’s cement industry relies on coal and petroleum coal as key sources of thermal energy needed to run the factories. The cost of energy is 50-70% of the total cost of cement production in Egypt.
Cement clinker is usually mixed with gypsum and other admixtures for a specific property before sent into the cement mill. In a cement mill, they are finely ground until reach the fineness required for cement products. After grinding, cement powder is stored in cement silos and then packed in bags by cement packing machines.
mixture of coal and limestone in a liquid state by vertically moving air. The process effectively removes sulfur and nitrogen from coal, thus reducing sulfur dioxide and nitrogen oxide from coal-burning emissions. clinker – A hard substance produced in cement kilns, which is ground with gypsum and other additives to make cement.
Coal is used for heating the raw materials at 1450 degrees centigrade to turn into clinker. The grade of coal supplied in the cement manufacturing industry depends on the grade of limestone used in the cement manufacturing process. If the limestone used in the cement manufacturing process is of high grade then low-grade coal is used and vice versa.

The coal mill adopts an edge driving system, is driven by the motor through the reduction gear and large and small gears. Raw coal is fed into feeding device of coal mill in cement plant, the hot air with temperature about 300 ℃ through the duct into the feeding device, there is a special lifting board in drying storehouse board will raise the raw coal, and helps the raw coal …
Higher the AM, lighter the color of clinker (cement). Normal range of SM is 1-2.5. MgO is commonly present in raw meal. Some of the MgO (2%) is accommodated into the clinker mineral structure, while as extra MgO forms a crystal called periclase and causes mortar expansion. MgO up to 4 % is found common in clinker.
Jun 05, 2019 For example, in the cement industry, actual production shows that when the product fineness is in the range of 5 to 10%, the yield is reduced by 5% for every 2% reduction in fineness, and when the fineness is controlled below 5%, the mill output is decreased more.
Jan 20, 2016 Fuel is combusted to produce heat for the clinker production process; coal is the traditional fuel used in China's cement industry. The raw coal from the stockyard is crushed in a hammer crusher and fed to the coal mill. The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator.
After cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. The cement mill grinds the clinker to a fine powder. A small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. The gypsum controls the setting properties of the cement when water is added.
The cooled clinker is processed in the clinker grinding system. The clinker grinding system is comprised of two ball mills and a vertical cement mill, material bins and feeders, separators for each mill including a high-efficiency separator for the vertical mill, dust collectors, and material handling equipment.
