coal ash properties & impact on clinker quality. dear ted. is there any good impact when we use lignite as a fuel instead of other solid fuels with low ash content. as i have seen on net that flyash from lignite gives lime in the range of 20%. if it is 20% than this flyash can be used as a source of lime in raw mix. please explain me in detail

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Dec 04, 2013 re how to increase C3S & reduce freelime in clinker. Dear All. I am thinking to increase the % of Petcoke to 90% instead of 80% in the fuel mix. It will reduce the silica content by from fuel ash & will automatically result in more lime for combination & will result in more C3S & less C2S.I think it will also give reduction in free lime.
Other contributors to clinker formation include failure to remove soot and other deposits, poorly pulverized coal, and improper burner adjustments that result in inefficient mixtures of air and fuel. A firebox that's too small for the type of coal being burned coupled with infrequent ash removal also encourages clinker formation.
What Causes Clinkers in Coal Fired Boilers? Clinkers, or slag, are made up of elements and minerals found in coal which are non-combustible. When burnt, they melt and fuse together, forming lumpy ashes. For as long as we have operated coal boilers, clinkers have been a recurring problem, occurring in small stoves used for heating a home right

reference: Avoiding Clinker Formation in Thermal Power Plant Boilers Clinker or slag is a fused mass of non-combustible residue (ash) from coal. All coal has some amount of ash content; bad coal has more ash, that’s all. Oxidation of the minerals

Formation of the desired clinker minerals involves heating the rawmix through the temperature stages mentioned above. The finishing transformation that takes place in the hottest part of the kiln, under the flame, is the reaction of belite (Ca 2 SiO 4) with calcium oxide to form alite (Ca 3 OSiO 5): Ca 2 SiO 4 + CaO → Ca 3 SiO 5

3.4 Burning in a kiln formation of cement clinker. The next step in the process is to heat the blended mixture of raw ingredients (the raw mix) to convert it into a granular material called cement clinker. This requires maximum temperatures that are high enough to partially melt the raw mix.
