Introduction of Lime Rotary Kiln

1. Activated lime kiln is a kind of rotary kiln, it is the main equipment to burn active limestone, mainly for metallurgy, smelting and other large industrial production. The equipment consists of cylinder, supporting device, with hydraulic wheel support device, transmission, lubrication device, kiln seal device and other components

2. In the calcination process of lime rotary kiln , due to the material in the rolling state, the heat evenly, the combustion device temperature is easy to control, good calcination quality, the activity of limestone up to 350-400ml, and lime pollution is small, more conducive to gain high purity lime.

Advantages of Lime Rotary Kiln

1.Kiln-type structure of the lime rotary is advanced, the use of reliable rotary kiln at both ends of the combination of scales sealed, so that the air leakage coefficient of less than 10%

2.The use of composite refractory materials of Kiln lining to reduce the loss of radiant heat; make full use of waste heat, the kiln can be preheated into the secondary air to 700 ℃ or more, saving energy consumption.
