Introduce the Use and Features of Limestone Rotary Kiln

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.

Limestone rotary kiln, also referred to as lime rotary kiln or lime pit, has state-of-the-art framework of minimal strain loss and may successfully improve the warm-up result to ensure that the decomposition rate of limestone is usually as much as 20-25% just after preheating through the kiln. The two ends of your rotary kiln are with modular sealing process, which can make air leakage coefficient lower than 10%. The sealing program is manufactured up of composite refractory material, for reducing radiation heat reduction.Filling form or divisional ventilated cooler can make lime temperature up to 800℃ when it can be from cooler, and that is easy to transit and keep, and might preheat the temperature of secondary-kilning to over 7000℃.

Features of Lime Rotary Kiln:

1. At the middle calcined part of kiln, it keeps the combustion temperature at 1050℃ 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. This 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

3. Lime shaft 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).

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. 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.
