Gas burning lime rotary kiln is a kind of new emerging lime production technology. It is well known that lime is made from limestone. The main ingredients of limestone is CaCO3. After calcining, lime will become calcium oxide. Limestone can be decomposed into lime as long as a certain amount heat is provided.
1. Advanced burning mechanism and less heat loss
It adopts fully sealed calcining mechanism. Multi-layer refractory materials are adopted in internal kiln. The design lifespan is more than 5 years. Meanwhile, in order to use energy effectively, heat exchange is adopted by upper and lower kiln part, which mostly reduces thermal loss.
2. Advanced technology, high efficiency and good quality of lime
The machine designed by our company uses vertical preheater with advanced structure and lower pressure loss. These advantages can not only improve production efficiency. In addition, lime produced by this machine holds good quality and high activities. It is a kind of ideal energy-saving lime kiln equipment.
3. Advanced structure and high investment profits
The rotary kiln structure should be made according to flame length and output capacity. It is testified by practice that gas burning lime rotary kiln should be bigger instead of smaller. One should make sure good air permeability. In fact, the distributing device is simpler than that of coal kiln. The proportion of fuel gas and air is supposed to be rational. The working principle of this machine is very easy.
