Cement Manufacturing Components Of A Cement
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.
Environmental Guidelines For Cement Manufacturing
Cement kilns, with their high flame temperatures, are sometimes used to burn waste oils, solvents, and other organic wastes. these practices can result in the release of toxic metals and organics. cement plants are not normally designed to burn wastes; but if such burning is contemplated, the technical and environmental acceptability need to be.
