The Rotary Kiln was designed basically for the cement industry. Due to technological advancements, they became more versatile, and are currently used in a wide range of sectors, assisting in both commodity processing and heavy industrial applications. They have also provided the foundation for a slew of innovative industrial processes.
A Rotary Kiln Plant is a continuous-moving reactor positioned in an inclined or cylindrical direction. It behaves as a thermal processing furnace used to heat solid materials at elevated temperatures to create a chemical reaction or physical change. They get commonly utilised for calcination, thermal desorption, organic combustion, sintering/induration, heat setting, and a variety of other things.
An Overview of Rotary Kiln
Cement, lime, and iron ore processing are the most common applications for industrial rotary kilns. The material gets rotated as it passes through the kiln to ensure it heats uniformly without depending on conduction.
The Rotary Kiln Manufacturers In India suggest that the shell, refractory lining, support tyres, driving gear, and internal heat exchangers make the fundamental components of a rotary kiln. Read the article further to learn more about each of these components.
Rotary Kiln Shell
It consists of rolled mild steel plates. The tendency of the shell to bend under its own gravity to an oval cross-section, resulting in deformation during rotation, sets upper limits on diameter.
The Tyres
Tyres, also known as riding rings, are made of a single ring steel casting with a smooth cylindrical surface. They attach to the kiln shell through different configurations. The tyre gets supported by a pair of steel rollers, spaced about half a kiln diameter apart. The rollers must support the kiln and allow for a feasible frictionless revolution.
The Refractory Linings
The refractory liner protects the steel shell from the corrosive qualities of the process material and insulates it from the high temperatures within the kiln. Refractory bricks or cast refractory concrete may get used. The refractory used is determined by the kiln's temperature and the chemical makeup of the treated material. The refractory life gets extended in the cement process by keeping a covering of processed material on the refractory surface.
The Drive Gears
The kiln gets rotated by a single Girth Gear that surrounds a cooler area of the kiln tube. It is common practice to supply an alternative drive for usage in the event of a power outage. It might be a small electric motor but is powerful enough to avoid harm.
