Compared with traditional brick kiln, modern lime kiln has such advantages as environmental protection and energy conservancy and high mechanical and automatic degree, and it can make full use of the cheap resources, especially use the gas that may produce pollution to the environment as the main energy source, so that it not only can protect the environment and the lime produced by this machine has high quality and low cost and can increase the economic benefits of the companies.
Lime kiln or lime rotary kiln has such advantages as environmental protection and energy conservancy and high mechanical and automatic degree. It can be divided large and mini lime kiln.
The limestone and the fuel are placed into the lime pit and preheated to 850℃, and then the limestone will resolve, and when the temperature reaches 1200℃, the calcining process will complete, and after being cooled, the limestone is discharged out of the kiln, thus completing the production of limestone products.
