A lime kiln is used to convert lime mud into lime for reuse in the causticizing plant of the kraft recovery process. Many of the problems encountered in lime kiln operations can be related to kiln chemistry, including TRS and SO2 emissions, dusting, ringing and refractory brick thinning. Understanding the composition and thermal behaviour of

CEMENT ROTARY KILN Questions & Answers Question-1: What is the maximum continuous shell temperature a kiln stands without permanent damage to the shell? Answer-1: 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.
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.

The rotary kiln of indirect heating is a cylinder rotating on bearing rims mounted on the frame and covered by a fixed case where hot gases are pumped during the kiln operation. These gases heat up the outer surface of the rotary cylinder when touching it and provide transmission of heat to the processed material without any direct contact with it.

The rotation of the kiln stirs the lime mud as it travels to fully expose it to the heat. By the time the lime mud complete its journey to the lower end of the kiln, it is about 98% calcined. The lime is now ready to be reused in the recaust process. The design and operation of a rotary lime kiln will be described next. ×

Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction.These treatments can be applied to powders, granulates, suspensions and green bodies.A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
