Wet Process Rotary Cement Kilns

General layout of a direct fired countercurrent rotary kiln used in cement manufacture Rotary kiln body with drive gear and 2 tyres riding rings A rotary kiln is a pyroprocessing device used to raise materials to a high temperature calcination in a continuous process

The kiln has to operate continuously in order to ensure a steady regime and therefore uniformity of clinker The larger existing kiln in a wet process plant produces 3600 tonnes of clinker per day The manufacture of cement by wet process is energy intensive and thus uneconomical as compared to dry process and semi dry process

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 It has to be long because a lot of water has to be evaporated

Mar 17 2006· Currently the design of chain systems for wet process rotary cement kilns depends strongly on experience Systematic theoretical and experimental investigations for the dimensioning of chain systems are not known Based on a one-dimensional cell model a simulation program for wet process rotary cement kilns with chain systems has been developed

Rotary Cement Kiln Process Kiln feed for a wet process kiln has a water content of approximately 40 In the charging zone of a wet process kiln steel chains are used as heat exchangers in the drying process Chains extract heat from the kiln s hot exhaust gases to dry the slurry feed

process and the wet process in a cement rotary kiln 7 The chemical reactions that take place during clinker formation however were not taken into account and the temperature of the gas phase was fixed at a uniform value The formation processes of the clinker phases include a series

Rotary cement kilns 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

Rotary cement kilns can be classified into wet-process kilns semidry kilns dry kilns preheater kilns and precalciner kilns All of these are described in the book by Peray 1986 and many others hence we will not dwell upon them here Rather we will briefly show the pertinent process chemistry and the heat requirements that drive them so

In contrast to static kilns the material passes through quickly it takes from 3 hours in some old wet process kilns to as little as 10 minutes in short precalciner kilns Rotary kilns run 24 hours a day and are typically stopped only for a few days once or twice a year for essential maintenance

The Rotary kiln is the main equipment of calcining cement clinker which has been widely used in cement metallurgy and chemical industry The equipment is composed of cylinder supporting device supporting device with catch wheel transmission device active kiln head kiln end sealing device burning device etc components
