Refining processing Rotary Kiln, not only labor intensive, but also a long time, as long as careful operation, it can prevent the mixing of the Rotary kiln.This happens mainly: coarse coal particles in the material sphere, blending large and uneven mix of coal in oxygen-rich surrounding, fuel combustion intense.Heat generated, coupled with the role of coal ash fluxing, so the occurrence of bonding materials and refractory bricks. Arise when dealing with difficult refining furnace, the first stop feeding, increased blast (the material to cool), and then open a gap along the Rotary kiln wall, then gradually refining the junction portion pry down, handle refining furnace, not only labor-intensive, and a long time, as long as careful operation, it can prevent the mixing of the Rotary kiln.Refining side of ring is mainly due to high temperature, liquid volume generated, the operation can not keep up, causing uneven ventilation, so the adjustment should be reasonable in the production of wind, coal, material cooperation, strengthen operations, maintain plus balance between reducing the calcined material and ventilation, so that even the Rotary kiln ventilation, light dark fire kept firing, stable primer position.
