Rotary Kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include:

Cement

Lime

Refractories

Metakaolin

Titanium dioxide

Alumina

Vermiculite

Iron ore pellets

Building materials

Rotary Kiln Structure

The basic components of a rotary kiln are the shell, the refractory lining, support tyres and rollers, drive gear and internal heat exchangers.

The kiln connects with a material exit hood at the lower end and to ducts for waste gases. This requires gas-tight seals at either end of the kiln. The exhaust gas may go to waste, or may enter a preheater which further exchanges heat with the entering feed. The gases must be drawn through the kiln, and the preheater if fitted, by a fan situated at the exhaust end. In preheater installations which may have a high pressure-drop, a lot of fan power may be needed, and the fan is often then largest drive in the kiln system. Exhaust gases contain dust and there may be undesirable constituents such as sulfur dioxide or hydrogen chloride. Equipment is installed to scrub these out before the exhaust gases pass to atmosphere.

Rotary Kiln Working Principle

The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large burner. The fuel for this may be gas, oil or pulverized coal.

Rotary Kiln Application

1. Rotary kiln is commonly used in the production process of catalytic agent, molecular sieve and zinc oxide, etc. As a result, you can find a rotary kiln in variety of industries, like steel annealing and nonferrous smelting industries, metallurgy and chemistry fields, and building industries, and more.
2. Rotary kiln system, which is also called a rotary calcine kiln, is a commonly used building material machine. Classifying by material properties, a rotary kiln falls into cement kilns, metallurgy chemical kilns, and lime kilns.
