Analysis of working principle of cement rotary kiln
Author:
Cement rotary kiln is one of the core equipment for calcining cement clinker in cement production line, which is usually composed of rotary cylinder, supporting device, transmission device, roller wheel, sealing device and so on. Cement raw materials are continuously pushed forward in the rotary kiln, undergo various physical and chemical changes at high temperatures, and eventually become clinker. The working principle of cement rotary kiln mainly includes the following steps
First, the cement raw material enters from the feed end of the rotary kiln and continuously rolls on the inner wall of the rotary cylinder.
Secondly, the raw material undergoes drying, preheating, decomposition, roasting and other stages at high temperature, and gradually forms cement clinker.
Then, the clinker gradually moves to the discharge end in the rotary cylinder, and at the same time, it continuously rolls in the cylinder and is affected by the high temperature air flow to ensure the uniform calcination of the clinker.
Finally, the clinker leaves the rotary kiln and is cooled by the cooling system to become the final cement product.
In general, the cement rotary kiln gradually converts cement raw materials into cement clinker through stable rotary movement and high-temperature calcination process. In this process, it is necessary to strictly control parameters such as temperature, air flow and feed rate to ensure the quality and output of cement clinker in production.
