Raw Meal to Clinker Ratio Nature Mathematics Free 30

You can just use the standard raw meal to clinker ratio calculation. ie.1 / (1R/100) where R = LOI of fresh raw meal. In your case this calculates to- 1 / (135.2/100) = 1.54 To answer your second question regarding the case of 4 bypass dust with an LOI of 4.4 the ratio will not be 1.65 it will be 1.726.

An investigation of clinker vs. formation heating profile and rotational velocity were conducted and the influence on the clinker phase composition and clinker agglomeration was deduced. Independent of the raw meal used the different clinker phases were formed in three stages 1. C

Incorporation rate of recycled aggregates in cement raw meals

In the cement raw meal recycled aggregate mainly substitutes marl. Higher incorporation rates are observed for recycled concrete aggregates (20–21 ) compared to mixed aggregates mainly because of their higher calcium oxide content. The burnability of raw meals and the final clinker composition are only slightly modified by CDWs.

Dear Ted thank you for your valuable inputs Firstly will the correction factor (1.08 as in above case ) hold good irrespective of your solid flow meter which measures the feed rate( ie. dust recirculation starts after the feed rate is measured ) And secondly the LOI of the bypass dust is 4.4 in our case hence as per the calculation the factor will be 1.65

Raw meal to clinker ratioPage 1 of 5

Re Raw meal to clinker ratio. The true raw meal to clinker factor is given by 1/(1Loss 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.
