Maintenance Management System
Maintenance often represents the most considerable controllable operating cost in the cement industry and a critical business function. Maintenance should be regarded in best-practice organizations not simply as a cost to be avoided but as a department that controls the company’s assets with a well-organized reliability engineering to a high leverage business function.

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

The cement kiln
Wet process kilns. The original rotary cement kilns were called ''wet process'' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.
