Cement mill
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 available.Inquire Now

Cement History of cement Britannica
Cement History of cement The origin of hydraulic cements goes back to ancient Greece and Rome. The materials used were lime and a volcanic ash that slowly reacted with it in the presence of water to form a hard mass. This formed the cementing material of the Roman mortars and concretes of 2,000 years ago and of subsequent construction work in western Europe.Inquire Now

Uses, Benefits, and Drawbacks of Fly Ash in Construction
ash is a pozzolan, a substance containing aluminous and siliceous material that forms cement in the presence of water. When mixed with lime and water, fly ash forms a compound similar to Portland cement. This makes fly ash suitable as a prime material in blended cement, mosaic tiles, and hollow blocks, among other building materials.Inquire Now

High Activation Grinding Industrial Efficiency
Compared to ordinary Portland cement (OPC), higher usage of blended cements is restricted by low pozzolanic and/or latent hydraulic activity, resulting in low compressive strength. An improvement on the reactivity of the blended cement constituents, namely the clinker, fly ash, and slag, is introduced through mechanical activation by highenergy milling.
