Rotary kiln is a direct heating type with rotary shell, which fires material through heat exchanging by contacting hot air (high temperature gas) generated by the burner provided at one end of the shell directly with the material. The shell internal wall is lined with firebricks for the shell protection subject to respective conditions. Furthermore, heat-resisting bricks are used for the lining as needed. The flow directions of the material and hot air (high temperature gas) are countercurrent, in general. According to the applications, however, concurrent flow may be introduced or a hot air generation unit may be provided in addition. It is also possible to mix solid fuel in the material or to provide a self-combustion process in the kiln. Furthermore, perfect air sealing is provided at both ends of the kiln shell, which makes it possible to keep the kiln internal atmosphere acid, neutral, or reducible in accordance with the applications.
Bricks The bricks are determined according to the time-proven performance from every aspect such as temperature distribution in the kiln, wear resistance, and scientific properties (i.e., acidity, neutrality, and reducibility) of the material. As for the joints, dry joints are used normally, while mortar joints are used as needed.
Combustion unit Generally, heavy oil or gas is used for the heat source, which enables either of mono-fuel combustion or multi-fuel combustion according to the combustion conditions. In either case, continuous automatic operation is facilitated through the temperature detection at a set position. The flame monitoring safety device is provided preparing for the contingency.
Equipment before/after kiln Before or apart from the kiln, normally will be a pre-heater. Usually, after the kiln, a rotary cooler is used.
