Raw Meal Ball Mill Used For Cement Plant

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;-

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

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...
