A quick summary of Chemistry in Kiln for Cement industry     TO MAXIMISE CEMENT QUALITY TO MINIMISE PRODUCTION COSTS TO COMPLY WITH LEGAL REQUIREMENTS UNDERSTAND AND CONTROL  THE PROCESS AT ALL STAGES  • Decarbonation of raw materials Limestone: CaCO3 to CaO + CO2 The fuel cream CxHy(N,S,…) + Aire to CO2 + H2O + (NOx, SO2, …) Cement is manufactured through a closely controlled chemical combination calcium ,  silicon ,  aluminum ,  iron  and other ingredients. Common materials used to manufacture cement include  limestone , shells, and chalk or marl combined with shale, clay, slate, blast furnace slag,  silica  sand, and  iron  ore.

Coolax Cooler, design and operation CIS - Controlled Impact System CFG - Controlled Flow Grate RFT - Reduced-Fall Thru Grate   The COOLAX high efficiency  grate cooler has greatly improved heat recuperation com-pared with traditional coolers. The efficiency of a grate cooler may be characterized in terms of cooler loss, this being the amount of clinker heat not recirculated to the pyro process. Traditional cool-ears have a loss of about 140 kcal/kg clinker. The COOLAX has a loss of only 95-100kcal/kg clinker. In the heat recuperation zone (CFG zone)the cooling air is supplied direct to the grate plates through a system of ducts and hollow beams instead of via an under grate compartment as in conventional coolers. On l ya small portion of the air enters the clinker bed from the under grate compartment This is the sealing air. The CFG zone is divided into sectors sup-plied with cooling air from separate fans. These ctors are subd...

Clinker Coolers Introduction for cement industry

Clinker Coolers Introduction for cement industry In the beginning, I offer you the simplest information about Clinker cooling is achieved by passing air streams through the grates. Due to an oscillatory movement, the grates cause the  flow and the spreading of the solid material. The thickness of the bed depends on the speed of the grates as well as on the mass rate of clinker  in  the  kiln  outlet.  Consequently  a  heat exchange is  performed between clinker  and air.  A part of the hot air volume is introduced inside kiln as secondary  air  and  used  for  the  fuel  combustion, while the  rest is  evacuated towards the  de-dusting filter characterized as exhaust air. Efficiency of the cooler  includes  two  operations:   (i)  The  heat recuperation from the clinker entering to the cooler, (ii) the cooling of the clinker. A fast cooling, i.e. a ...

CF Raw Meal Silo How it works  The CF (Controlled Flow) silo is a continuously operating system for homogenization and storage of cement raw meal, where the material is extracted simultaneously at different flow rates from a number of outlets in the silo bottom. The CF system, including suitable kiln feed equipment, ensures stable kiln feed composition at minimum power consumption and investment cost. The efficient performance of the CF homogenizing silo results in stable kiln operation so that changes in kiln speed or firing rate are rarely needed and stable coating in the kiln is maintained. In order to ensure high homogenization efficiency, all the raw meal in a silo must be kept in constant movement towards the outlets. Furthermore, the raw meal must pass through the silo in flow zones with different residence time. The CF silo complies with these demands. It extracts raw meal at different rates from several outlets in the silo bottom and mixes the stream from these outlets. Th...
