The original rotary cement kilns were called 39wet process39 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
The cement rotary kiln is mainly used for calcining cement clinker, and is divided into two types cement kiln and wet kiln. Ceramsite ceramsite is made from various kinds of clay, slate, shale, coal gangue, and industrial solid waste.
Cement rotary kilns refer to cement rotary calcining kilns sometimes called rotary furnaces. It is a pyroprocessing device used to heat materials to high temperatures in a continuous process. The kiln body is a cylinder vessel with a certain degree of tilt to the horizontal level.
The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature. In a straight grate, the pellets at the top of the bed are over cooked and those at the bottom are under cooked. Higher quality means fewer fines, better reducibility and less variation in compression strength.

CEMENT ROTARY KILN Questions amp Answers Question1 What is the maximum continuous shell temperature a kiln stands without permanent damage to the shell Answer1 The maximum recommended kiln shell temperature varies by plant, by country and by kiln manufacturer, despite the fact that most kiln shells are made of low alloy carbon steel.
Cement rotary kilns are commonly referred to as the largest piece of rotating equipment in the world. Ranging in diameter from 10 feet to more than 20 feet, they are often many hundreds of feet long. As the kiln rotates on its rollers, material is transported due to the kilns low, gradual slope.

Refractory, or the lining utilized on the interior of rotary kilns, is a critical component in ensuring process efficiency and prolonging the life of a rotary, well discuss everything you need to know about refractory, including how it works, the different types, and best practices for preventative care.
Re CLINKER FROM ROTARY OR VERTICAL SHAFT KILN. Dear Davide, There are a number of reasons why the clinkers might differ, but buying clinker from a VSK would not be a completely wrong move. It would depend on the degree of combination of the clinker, the lime saturation and the silica modulus.
A rotary kiln is a pyroprocessing device used to raise materials to a high temperature calcination in a continuous produced using rotary kilns include Cement Lime Refractories Metakaolin Titanium dioxide Alumina Vermiculite Iron ore pellets They are also used for roasting a wide variety of sulfide ores prior to metal extraction.
A. A Boateng, in Rotary Kilns Second Edition, 2016. 10.4 The CementMaking 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

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 3045 water, or they were ground dry, to form a
Design features of rotary cement kilns. The shell of the kiln is made of mild steel plate. Mild steel is the only viable material for the purpose, but presents the problem that the maximum temperature of the feed inside the kiln is over 1400C, while the gas temperatures reach 1900C.
Rotary cement kilns as used in the cement industry take the form of a long cylinder supported on rollers. They vary greatly in diameter and length, from 1.5 18 m to 4 140 m. In the larger kilns the ratio of length to diameter generally varies between 30 and 401. The rotary drum is installed at an incline of 35, and generally
