How to Select a Suitable Refractory Brick for Rotary Kiln?

There are many factors which influence the production of rotary kiln, the limitations according to the empirical formula to calculate, but relative to reflect the change rule of some factors, for reference. As for 5-grade suspension preheater kiln, while 600 t/d clinker production, its grade C2 and C5 preheater is Φ4100 mm, can match Φ3 m * 48m rotary kiln; When C2 and C5 diameter is Φ3700 mm, with the specifications of the rotary kiln is Φ3.2 * 52 m may not suitable . Same for precalcining kiln, different types and specifications of the decomposition furnace and preheater, will have great influence on rotary kiln clinker production. Henan macro secco today heavy rotary kiln mesh weaving said firebrick would need what kind of performance:

1, the fracture resistance. For any of the open kiln and kiln and abnormal operation, will cause severe changes of temperature. Therefore, fire-proof material must possess the necessary thermal shock resistance to resist the temperature change. Otherwise, the refractory material will break. Often referred to as the burst fracture, at the levels of firebrick direction.

2, chemical corrosion resistance, slag resistance) in the process of clinker burning, burning effect of steam, ash and slag erosion can have chemistry with the refractory brick and refractory brick (depending on the type of fuel used). In addition, enter in dusty gas of kiln and alkali materials can also be attached to the calcining zone on the brick to the reaction. Refractory to resist chemical attack ability to be a slag resistance of it. Don’t have this kind of resistance to slag, refractory brick will be chemical erosion and significantly weakened, making refractory kiln lining premature failure.

3, wear resistance. Rotary kiln in the conditions and requirements refractory raw materials must be able to withstand sliding layer and mixed dust in the air flow generated by the friction effects. Don’t usually forming dense skin before and after the bricks in...
