Cement mill - WikipediaThe emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material. Because of this, cement continued to be ground very coarsely (typically 20% over 100 μm particle diameter) until better grinding technology became.grinding in cement tecnology,Cement Grinding with Roller Press Technology – Buildotech MagazineAug 20, 2016 . The existing trend of finish grinding technology in cement manufacturing shows 50% market share of ball mills, 40% market share of VRMs and 10% of others like roller presses. Finish grinding consumes 35-40% of total electrical energy required for cement production. This is one of the areas where huge.
