CEMENT RAW MATERIALS - International Cement Review

2013-6-9  The raw materials which supply cement works, and which may be required in quantities of over 4,000 tonnes per day, must be thoroughly proven if the plant is to run successfully. Consistent quality feed is required and an extraction plan must be made to ensure that a uniform flow of raw material will always be available to the kilns.

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
