Rotary kiln can be used in brick industry

Refractory Brick physical properties of slag resistance is refers to the refractory material’s resistance to chemical attack ability, in the initial formation of rotary kiln skin layer and when the material viscosity big or produce local high temperature make rotary kiln skin off cases, slag resistance is very important. To feeding into the kiln is the best way to deal with the rotary kiln ash, widely used in wet process kiln, it can be dry kiln ashes from the furnace chain with the hot end of the outlet directly feeding furnace, not mixed with slurry, and from a preheater kiln, also not after the chain belt, so won’t produce slurry pipe plugging into the kiln and mud ring phenomenon. In the kiln feed includes conveying system and feeding system.

Porosity and coefficient of thermal conductivity, to form the rotary kiln skin initial layer has an important role in the rotary kiln, and local skin off, porosity and coefficient of thermal conductivity larger refractory help rotary kiln skin timely posthumous. But at the same time may have showed great damage effect, make brick peel off the thin layer. Rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cementindustrial and coal slime in coal mine,etc. Rotary dryer can be widely used to dry various materials, and it is simple to be operated.

Refractory Brick in its production process, the physical and chemical change usually fails to reach the firing temperature of the equilibrium state. Also have burnt inadequate brick, so the rotary kiln in action again under high temperature effect, most of the refractory brick because of its own liquid production and the pore filling, an irreversible heavy burn contraction. Therefore, the high temperature volume stability, in selecting calcining zone brick must be considered. Hot surface shape divide into rotary kiln firing with rotary kiln lining through heat the main form of earthquake damage; If occur at the same time local rotary kiln skin off, can make the brick service life is much shorter.
