Re: Raw meal to clinker ratio. The true raw meal to clinker factor is given by: 1/(1 – Loss on ignition of kiln feed). It is normally about 1.55. The major variation from plant to plant arises because of the dust loss from the kiln feed, which varies from kiln to kiln dependent on the collection efficiency of the top stage preheater cyclone.
