Raw Mill – Kiln Application in Cement Industry | Thermax

The existing system consisted of Gas Conditioning Tower (GCT) followed by Electrostatic Precipitator (ESP) for the control of particulate emissions from the kiln and raw mill Since the existing circuit was designed in early 90’s for lower capacity of Kiln, CCCL wanted to look at the various alternatives to reduce the emissions going out ofequipment for raw meal storage and kiln feeding IKN’s responsibility included detailed engineering of process ducts, material and dust transport, steel structures, and the integration of the raw mill into the new plant The raw mill circuit followed the two fan system and was delivered under a separate contract between Italcementi and GebrModifications at Matera IKNCement Kiln Optimization Controlling a cement rotary kiln is a very difficult task The process is intrinsically unstable the grinding circuit of a raw mill are an increase in output and a reduction in power consumption Expert Optimizer has been successfully applied in more than 90 mills, toIndustrial : Optimization for the Cement Industry

Re: Raw meal to clinker ratio Page 3 of 5

Yes, as long as the dust streams from raw mill bagfilter and kiln gas conditioning tower both return directly to the kiln, the 'raw meal to clinker ratio' is the same as calculated in my first post above I have taken the mass balance of the circuit and found your calculation is perfect to 100% Reply 72 posts Time Posted 23/08/2010 21X x Stops as part of feed to raw mill group 15 Kiln / Raw mill ESP All rectifiers stop x X x x x 16 Limestone weighfeeder stop 17 Sand / Bauxite / Laterite W eighfeeder stop 18 Shale / Siltstone W eighfeeder Stop 19 Iron ore weighfeeder x X(1) X(1工艺工程师培训 ppt课件百度文库Cement Kiln Optimization Controlling a cement rotary kiln is a very difficult task The process is intrinsically unstable the grinding circuit of a raw mill are an increase in output and a reduction in power consumption Expert Optimizer has been successfully applied in more than 90 mills, toIndustrial : Optimization for the Cement Industry
