Raw materials - Understanding Cement

Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material for blending. Most of the material is usually ground finer than 90 microns - the fineness is often expressed in terms of the percentage retained on a 90 micron sieve. Once the the raw materials are ground fine enough, they are blended in ...
