The secondary rotary kiln kiln crust is composed of clinker or dust since liquid or semi liquid phase into solid form; it has a very important role in the production of rotary kiln; but due to improper use, which may affect the stability of the secondary rotary kiln; thus causing some unfavorable factors on the whole a production process; so today we will try to understand some basic conditions for stable kiln crust;
1, kiln material (including the mixture of kiln ash and coal ash, etc.) composition and appropriate to the kiln temperature, can form a number and viscosity of the melt is appropriate;
2, the composition and structure of the lining brick (mainly the appropriate distribution of pores in the brick) has certain adaptability to the kiln material, which is beneficial to the adhesion of the brick surface and the proper penetration into the brick, forming the mechanical anchoring to stabilize the kiln skin.
3, the kiln body is in good condition, the degree of the ellipse is not big, the kiln is running normally, the number of the kiln is less. The combustion zone only in normalizing site of clinker kiln skin temperature is higher than the actual Hang Hang kiln temperature should be higher than the skin temperature of the coating, it is stable with the kiln. Normalizing before and after firing on both sides of the site in the band, especially before and after the firing zone on both sides of the transition zone, the actual kiln material coating temperature is lower than the proper temperature, become unstable with the kiln.
In fact, after all the secondary rotary kiln rationality depends on the stability of operation, and the lining brick brick composition, temperature gradient, kiln equipment and other factors; as long as the attention to these aspects, so will the stability of ki
