1. Working principle of rotary kiln
The kiln is a cylindrical vessel, slightly inclined to the horizontal, slowly rotating about its longitudinal axis. The process raw materials are fed into the upper end of the cylinder. As the kiln rotates, the material gradually moves to the lower end and may be subject to a certain amount of stirring and mixing. Hot gases flow along the kiln, sometimes in the same direction as the process material, but often in the opposite direction. The hot gases can be produced in an external furnace or can be produced by a flame inside the kiln. This flame is emitted from the burner tube and acts like a large Bunsen burner. The fuel can be natural gas, petroleum, powdered petroleum coke or pulverized coal.
2. Rotary kiln structure
The basic components of a rotary kiln are the kiln shell, refractory lining, support wheels and drums, transmission device and internal heat exchanger.
