What is a rotary kiln system?

Rotary kiln is the key equipment in cement production and minerals calcination for nonmetal minerals such as limestone, gypsum, bauxite and metal minerals such as lithium ore, nickel ore, magnesium, zinc, etc. The main parts of a typical horizontal rotary kiln are its drum shell body and the burner system. The drum shell body has a certain slope, material enters the kiln from its higher end, and move forward to its lower end, on the opposite, hot air from the burner enters the drum shell body from the lower end and move forward to its higher end, in this process, the material get calcined in a very high temperature.

Rotary kiln working process and main structure

How does a rotary kiln work?

*Rotary kiln is composed of cylinder body, supporting device, retaining wheel supporting device, transmission device, kiln tail sealing device

1. When a rotary kiln is running, a main drive motor transmits power to the gear device through the main reducer to drive the rotary kiln.

2. The material enters the kiln from the kiln tail (the higher end of the cylinder) . With the inclination and slow rotation of the cylinder, the material rolls in the circumferential direction and moves from the higher end to the lower end, and the raw clinker enters the cooler for cooling through the kiln head cover.

3. The high-temperature calcining gas is injected into the kiln from the kiln head, and the waste gas produced by combustion is discharged with the material, and then discharged from the kiln tail.
