Manufacturing Process Grey Cement. ... An electrostatic precipitator dedusts the raw mill gases and collects the raw meal for a series of further stages of blending. The homogenized raw meal thus extracted is pumped to the top of a preheater by mechanical transport /FK pumps. In the preheaters the material is heated to 750ºC.
A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement.
Universityof Sulaimani College of Science chemistry dept. Cement manufacturing process prepared by: 1Haval Arf 2Rawand Wahid 2. Cement and history Cement is a common construction material, that hardens in the presence of water.
The entire manufacturing process in a modern plant is now controlled through a microprocessor based programmable logic control system to maintain uniform quality of cement and a high rate of production. The entire operation of the plant is controlled centrally in a single control room and the plant ...
Cement production is either "wet" or "dry", depending on the water content of the material feedstock. The wet process was the original rotary kiln process developed at a time when material handing of slurries was more developed than those of dry powders.
In this process, the chemical bonds of the raw materials are broken down and then are recombined into new compounds. The resulting clinker (rounded nodules between 1mm and 25mm across) is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality .
The cement manufacturing process starts from the mining of limestone, which is the main raw material for making cement. Limestone is excavated from open cast mines after drilling and blasting and loaded on to dumpers which transport the material and unload into hoppers of the limestone crushers.
