Rotary lime kilns can be over 100 m long with an inner diameter of 4 m. The top of the inclined kiln (i.e., the feed end) is where lime mud enters the kiln and carbon dioxide gas is exhausted. Lime has a residence time of roughly 2 to 3 hours in the kiln depending on the slope of the kiln (approximately 2º) and the speed of rotation (roughly 1 ...
A 2D axisymmetric computational fluid dynamics (CFD) model, coupled to a 1D bed model, has been developed to capture the key processes that occur within rotary lime kilns. The model simulates the calcination reaction using a shrinking core model, and predicts the start of calcination and the degree of calcination at the end of the kiln. The …

Brief Introduction to Wet Rotary Kiln Process. The kiln body of wet rotary kiln is usually relatively long (the aspect ratio is 30-40). In order to increase the heat transfer area of the kiln, the chains are often hung at the kiln tail to accelerate water evaporation.
Rotary lime recovery kilns in the pulp and paper industry range in size from 7 ft (2.1 m) in diamet er by 175 ft (53 m) long to 15 ft (4.6 m) in diameter ... burning conditions in the kiln. On a dry basis, lime mud typically contains about 95 wt% CaCO 3 and 5 wt% of impurities. As lime mud moves through the kiln, the
ROTARY KILN CONSTRUCTION. While FEECO rotary kilns are custom designed around the material to be processed, in general, there are some standard components that serve as the basic design of a rotary kiln. The diagram shown on page 8 illustrates some of the common standard components found on a basic direct-fired kiln.
The kiln system in which the clinkerization takes place is a rotary kiln with or without additional infrastructure called as "suspension preheaters" and pre-calciner. The rotary kiln is a rotating steel tube with a length to diameter ratio between 10 and 40. A slight inclination of 2.5 to 4.5 degrees is provided for a smooth flow of material.
In particular, rotary kilns are also used to burn Dolomitic limestone at high temperatures to produce sintered Dolomite. Fig. 1 Component parts of a gas fired Rotary Lime Kiln A rotary lime kiln is mainly composed of a driving device, supporting roller, catching roller, cylinder, kiln inlet, kiln outlet and a sealing device. 1.
Rotary kilns account for 90% of lime production in the United States. A rotary kiln consists of a long, cylindrical, slightly inclined, refractory-lined furnace. The limestone and combustion gases pass through the kiln in a countercurrent flow. As the limestone moves down the kiln, the limestone is heated and slowly calcined into lime. The lime ...
