The cement clinker calcination is an important step in the cement production process. It mainly occurs in cement kiln and can be roughly divided into six reaction stages, namely drying, preheating, chemical decomposition, exothermic reaction, sintering and cooling.
A. A Boateng, in Rotary Kilns (Second Edition), 2016. 10.4 The Cement-Making Process. Rotary kilns are synonymous with cement making, being the workhorses of this industry. There are many types of rotary kiln arrangements for producing cement clinker with each incremental design goal aimed at improving energy efficiency, ease of operation, and product quality and minimizing environmental

Early clinker composition. The phase diagram for the CaO-SiO 2 (C-S) system (shown right) was first accurately determined by Day, Shepherd and Wright in 1906.This shows that there are four stoichiometrically distinct calcium silicates (each with multiple polymorphs): CS, C 3 S 2, C 2 S and C 3 S.Portland cements contain mixtures of C 2 S and C 3 S.The zone containing Portland cements is
Rotary Kiln Processes With the arrival of rotary kilns in Britain in 1900, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a
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.
Many cement plants use bituminous coal as the fuel of rotary kiln, so the ash content, volatile matter, calorific value, fineness and moisture of coal fines will affect the clinker calcination process in the kiln.
Firing of cement clinker. In the rotary kiln, the carbonate is further rapidly decomposed and a series of solid phase reactions occur to generate cement clinker. After a series of chemical reactions, the high temperature clinker discharged from the rotary kiln is cooled by the cement clinker cooler.
Cement kiln is mainly used for calcining cement clinker, which can be divided into dry production process cement kiln and wet production process cement kiln. Rotary kiln is widely used in building materials, metallurgy, chemical industry, environmental protection and many other production industries.
Clinker produced by early static kilns was in the form of large pumice-like lumps. Rotary kiln clinker on the other hand, because of the rolling action of the kiln, emerges as fairly regular roughly spherical hard nodules of diameter typically 5-50 mm, together with a certain amount of dust abraded from the nodule surfaces.. Clinker minerals react with water to produce the hydrates that are

Mar 01, 2020· The main component of cement, the so-called cement clinker, is mainly produced in rotary kilns after the drying and calcination process. The raw material, mostly limestone and clay, is ground, dried, deacidified in a pre-calciner and then burnt in the rotary kiln to produce cement clinker.
