How to eliminate the lack of fire and burning lime harm? Why?
To eliminate the impact: the fire and excessive lime can be used in the lime slurry should be stored in the pit for more than 2 weeks (known as "Chen Fu"), so that the aging of the particles are fully cured. This reduces their impact.
Hazard: 1) burning lime is very slow, it may be cured after lime application, its volume expansion, resulting in drum cracking, affecting the quality of the project. 2 the lime under fire can reduce the quality of lime and the ash content of limestone.
When the kiln lime stone is larger, the calcination temperature is high, the center of lime stones to the decomposition temperature, the surface has more than the decomposition temperature of limestone coarse grain obtained, slow aging reactions in water, which is called a lime.If the calcination temperature is low, the central part of the limestone can not be completely decomposed, which is referred to as lime.
