cement is made by heating limestone (calcium carbonate) with other materials (such as cla y) to. 1450 °c in a kiln, in a process known as calcinations, whereby a molecule of carbon dioxide is
air emissions in cement and lime manufacturing are generated by the handling and storage of intermediate and final materials, and by the operation of kiln systems, clinker coolers, and mills. several types of kilns are currently used in cement manufacturing (preheater– precalciner (php), preheater (ph),
cement is the basic ingredient of construction and the most widely used construction material. it is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
table 2.2: cement production and cement consumption in 1995 (figures in 1,000 tonnes) in the european union cement is produced in 320 plants of which about 70 are grinding plants without kilns. see table 2.3. the total number of kilns in the eu countries is 437. they are not all of them currently in operation. only very few kilns
during the first few weeks of operation after initial commissioning the capacity of the plant was increased further. table 2 shows a summary of process data as comparison of the former and new grinding system. conclusion and future developments schretter & cie upgraded its cement grinding unit by implementation of the new köppern 2-stage koesep
holtec has undertaken performance optimisation of the cement grinding circuits by doing process diagnostic studies in many cement plants. the paper describes the approach for the process diagnostic study for the optimisation of a ball mill circuit and is supported with typical case study done by holtec in a 1.5 mio t/a cement plant.

the main component of cement is clinker, which is produced from raw materials, such as limestone and clay. . limestone supplies caco 3 for the cement production. silica, alumina, and iron are considered to be other raw materials. the lime stone used for cement manufacturing contains 75-90 % of caco 3 and remainder is mgco 3
the ready-mixed concrete plants produce concrete and supply to different construction sites in a ready to use condition. the main operations in the plant involve batching of different ingredients of concrete such as cement, aggregates, sand water, chemical and mineral admixtures in
