Cement manufacturing components of a cement plant

Cement Manufacturing Components Of A Cement Plant

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.
