Depending on its characteristics, the raw material needed for the cement production process is quarried by blasting, hydraulic excavators or ripping. A wide range of crushing plants – depending on the material’s properties and type of extraction – can be used for breaking the extracted raw material to the size required by the raw mill.

Raw meal to clinker ratio - International Cement Review

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.

Re: Raw meal to clinker ratio - Page 2 of 5

In a kiln which is being fed with raw meal at 350t/h and has a 'raw meal to clinker ratio' of 1.55 (calculated without respect to bypass), the actual amount of clinker produced with say 10t/h bypass dust removal will be;-(350 / 1.55) - 10 = 215.8t. Therefore the 'raw meal to clinker factor' ,allowing for removal of this bypass dust, will be;-
