Cement Raw Materials used in Manufacturing of Cement

2 天前 Raw materials used for manufacturing of Portland cement are found naturally in the earth’s crust. It is made primarily from calcareous and argillaceous materials and gypsum. Calcareous materials contain limestone or chalk while argillaceous materials comprise an oxide of silica-alumina and iron. Both are found as clay or shale.

If the 'good stuff' is all used up first, it may be more difficult to make cement out of what is left. Careful selection on a day-to-day basis is needed to make the best use of all the materials available. Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material

RAW MATERIALS IN CEMENT PRODUCTION Primo

The main materials used in cement production are minerals containing calcium oxide, silex, alumina and iron oxide. These components are rarely found in one type of raw material; therefore, for the cement production the raw mix is selected for the following components:
