The raw material production of cement plant can be classified into four steps crushing, grinding, mixing and homogenizing. Crushing the limestone and other materials are ...
Limestone comprises 95% of core raw material for cement production. No wonder then that the cement sector governs demand, supply and pricing of limestone (as well as coal) to some extent. According to some estimates, around 180-250 kg of coal and about 1.5 tonne of limestone is required to produce a tonne of cement.

Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.

cement - cement - Extraction and processing Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary. Some deposits are mined by underground methods. Softer rocks such as chalk and clay can be dug directly by excavators.
The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industrys CO 2 emissions are caused by transformation of limestone into lime, called decarbonation. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.
