Limestone Rotary kiln is main equipment to calcine active lime

Limestone Rotary kiln is main equipment to calcine active lime, with simple structure, reliable operation and convenient automatic control. Active lime rotary kiln belongs to periodic heating furnace, it has a low heating demand to the liner materials. According to the physicochemical property and calcining requirement of the active lime, the silicate refractory material usually is not used as kiln lining. Therefore, that is to say, the lime pit lining materials must be alkaline or neutral refractory material. Kiln lining is not strange for everybody, it is set inside the kiln in order to protect the cylinder of Rotary kiln, it at the same time also affects the production and quality of the rotary kiln equipment. Henan Great Wall Mining Machinery Co., Ltd, is going to introduce you how to choose the lining materials for active lime rotary kiln.

Generally speaking, when calcining the clay brick, we should not only consider the heat preservation effect, but also consider the investment. When choosing the materials for burning zone of the limestone rotary kiln, we need to consider that the lining brick must have higher fireproof performance to resist the corrosion of alkaline matter. So usually we use the magnesia chrome refractories matter to conduct the masonry. At the same time, with the development of refractory technology, the magnesium aluminum spinel is widely used as the kiln lining in the active lime rotary kiln.
