CEMENT ROTARY KILN Questions 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.
Manufacturing the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the ...
Rotary cement kiln is regarded as the heart of cement manufacture in any cement plant widely used to convert raw material into clinker. The capacity of a plant is determined by the production in the kiln whose sizes can be very large to handle higher production capacities of as much as 10000 tonnes per day (tpd) of raw meal to be processed.
Maximum temperature: 1,300 °C. Forging rotary hearth furnace able to treat parts that weigh up to kg each for a production capacity of kg/h with temperatures up to °C. Heating is via regenerative low NOX burners.

With the arrival of rotary kilns, cement manufacturing processes became sharply defined as wet process or dry process. In the Wet Process, the kiln system is fed with a rawmix in the form of a liquid slurry, typically containing 3050% of water by mass. In the Dry Process, the kiln system is fed with a rawmix in the form of a dry powder.
Features. Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica bearing minerals toform a mixture of calcium silies. Cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type ...
