Lime is used for producing cement for the construction industry. Lime is very important for many other uses and chemical applications, to produce gypsum wallboard or drywall panels, to neutralize toxic chemicals, for air pollution control scrubbing systems, for neutralizing the acidity of soil for agricultural, and vertical shaft lime kilns are used for the production of sugar. Lime is used for pigment in paints.
Features of vertical shaft lime kiln:1. At the middle calcined part of kiln, it keeps the combustion temperature at 1050°C through dry gas and burning normally. The CO2 decomposed is discharged out by side road which can reduce the pressure of decomposed part so that the limestone can decompose sufficiently, improve the lime quality and capacity.
2. vertical shaft lime kiln uses innovative design to synchronize the limestone and lime to the whereabouts of uniform and by calcining zone. The activity of lime is more than 380ml (this kind calcining process eliminates the raw burning and over-burning phenomenon completely.).
3. we also solve the problems as long-term temperature resistance, anti-oxidation, anti-softening, anti-wear problems of burning part of vertical lime kiln, so this kind of kiln is known to the world.
4. It can control the air speed by drafter up the furnace to achieve energy saving and high yield. To choose low-sulfur coal can get good quality active lime with the sulfur content less than 0.03.
5. This vertical shaft lime kiln is mainly to solve the raw and over burning of lime to keep high activity of raw lime to reach the high requirements of refining steel companies and other industries demands.
