What is the baking standard of rotary kiln?

Whether the rotary kiln has achieved the expected effect can be checked after the kiln is cold, and whether the concrete and refractory bricks are dry, cracked, cracked and exposed, or even fall off, draw lots and drop bricks. If concrete and refractory bricks have been dried, their surfaces are smooth and flat, their original shapes remain unchanged, and there are no tiny water droplets, then they are baked. Another method is to judge the dryness in the drying process of rotary kiln. Before the rotary kiln is dried, the outward water can be seen at the manhole door at the kiln tail, the ash discharge valve of the preheater, the ash discharge valve of the settling chamber and the pneumatic lifting pump. With the extension of drying time, the moisture gradually decreased, and when the kiln was basically dry, no moisture flowed out, indicating that the kiln was basically dry. The so-called rotary kiln has been dried, which does not mean that the crystal water in the flue, preheater and kiln lining has been decomposed, evaporated and completely dried, but that most of the attached water has been dried, and the remaining small amount of attached water will not cause adverse consequences when heated and evaporated. If the lining is to be completely dried, it is difficult to completely dry it only by firewood or briquettes. Practice has proved that coal injection drying after basic drying is effective and an ideal operation method.
