Rotary kiln ia main equipment for calcining. In all kinds of high temperature calcining operation, such as ceramic production, iron ore calcination. Rotary kiln play an important role, and is the main part and equipment for hematite calcination process. Commonly known as the rotary kiln, the rotary calcining kiln is also called the rotating kiln, belonging to construction equipment. Depending on the materials, the rotary kiln falls into three types: the metallurgy kiln, the lime kiln and the cement kiln.

In the cement production of rotary kiln, the main drive of rotary kiln is DC motor, mainly the power of DC motor has the advantages huge power, and the superior speed control performance, less investment also can for most manufacturers save a substantial capital. In order to better operation of rotary kiln, produce high quality products, it is necessary for us to understand the relevant knowledge about rotary kiln driving devices.

In the whole production process of rotating kiln, the change of the current has certain characteristics, General when the rotary calcination kiln startup, because the role of the thermal and other objective factors of rotary kiln, the required power is very big, at this point in the rotating drying kiln motor current is larger, in the boot operation after a period of time, rotary kiln motor current began to decline, keep in a stable state. The other is slow-down kiln, often appear to back kiln phenomenon, at this time of the rotary kiln cylinder easier for reversal, this kind of reverse force will spread to the rotary calcining kiln motor, by this time motor will appear power status, this will cause certain damage to commutator, affect the service life of the commutator, so in the actual configuration need to be done in accordance with the certain requirements to control.
