The cement industry is one of the most intensive energy consumers in the industrial sectors. the energy consumption represents 40 to 60 of production cost. additionally, the cement industry contributes around 5 to 8 of all man-made co 2 emissions. physiochemical and thermochemical reactions involved in cement kilns are still not well understood because of their complexity.

Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. cements of this kind are finely ground powders that, when mixed with water, set to a hard mass.setting and hardening result from hydration, which is a chemical combination of the cement compounds with water that yields submicroscopic grinding mill.

The use of wastes as raw materials in the clinker burning process can replace a relatively large amount of raw materials. the quantities of wastes used as raw materials in clinker production have more than doubled since 2001. in 2004, waste raw materials used in clinker production allowed the cement industry to make a direct saving of almost 14 grinding mill.

The first step is to quarry the principal raw materials, mainly limestone, clay, and other materials. after quarrying the rock is crushed. this involves several stages. the first crushing reduces the rock to a maximum size of about 6 inches. the rock then goes to secondary crushers or hammer mills for reduction to about 3 inches or smaller.

This paper mainly introduces the raw mill in cement plant. in order to achieve the desired setting qualities in the finished product, a quantity 2-8, but typically 5 of calcium sulfate usually gypsum or anhydrite is added to the clinker and the mixture is finely ground to form the finished cement powder. this is achieved in a cement raw mill.

The pulp and paper mill although there are several chemical and mechani-cal pulping methods used for delignifying wood table 2-l, separating fibers, and removing discol-oration, all integrated pulp and paper mills involve the same general steps in the manufacture of pulp and paper. these steps include: 1 raw material.

The calcium looping co 2 capture process, cal, represents a promising option for the decarbonisation of cement plants, due to the intrinsic benefit of using the spent co 2 sorbent as a feedstock for the plant. the generation of sufficiently active cao from the raw meals entering the cement plant for the co 2 capture requires calcination of these materials at around 900 c in various grinding mill.
