RAW MATERIALS IN CEMENT PRODUCTION

  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 CARBONATE COMPONENT rich in calx is contained in the raw mix in a quantity

Cement manufacturing

Summary of production process Cement is typically made from limestone and clay or shale These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions This blended raw material is called the raw feed or kiln feed and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C In its simplest form the

Transportation of Cement

Packaging Cement if not carried in bulk is usually shipped in 50 kg paper bags or one/two tonne polypropylene bags These must be further packaged in water proof material as absorption of moisture or carbon dioxide from the air can significantly deteriorate cement over time The deterioration may not be visible but it significantly reduces its performance Solidification It is crucial to
