cement plants would increase to 115-130 kWh/t cement in 2030 and to 115-145 kWh/t cement in 2050. _____ PROCESS OVERVIEW – Cement is a solid material made of clinker, gypsum and other additives. It is mainly used to form concrete, a conglomerate of cement, water, fine sand and coarse aggregates, widely used for civil engineering constructions.
Aug 30, 2012· Cement Manufacturing Process Phase IV: Kiln Phase. Kiln is a huge rotating furnace also called as the heart of cement making process. Here, raw material is heated up to 1450 ⁰C. This temperature begins a chemical reaction so called decarbonation. In this reaction material (like limestone) releases the carbon dioxide.

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
The emergence of Portland cement in the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material. Because of this, cement continued to be ground very coarsely (typically 20% over 100 μm particle diameter) until better grinding technology became available.
Process technology for separate grinding on the other hand is well known in general. In most cases existing mill systems can be enhanced by transport and storage facilities. But depending on the given plant layout and the product portfolio the individual technical solutions for separate grinding and blending can significantly differ.

Cement kilns, with their high flame tempera-tures, are sometimes used to burn waste oils, sol-vents, and other organic wastes. These practices can result in the release of toxic metals and or-ganics. Cement plants are not normally designed to burn wastes, but if such burning is contem-plated, technical and environmental acceptabil-
