Classification and structure of lime rotary kiln

Lime rotary kiln is a professional lime production calcination equipment, according to the different materials, lime rotary kiln can be divided into lime rotary kiln and active lime rotary kiln. According to the structure and the principle of different equipment can be divided into horizontal rotary kiln, vertical rotary kiln. At present, the domestic is more widely used horizontal rotary kiln, our company produce rotary kiln with the best quality and perfect performance. It is widely used in the lime production enterprises.

Lime can be divided into ordinary lime and active lime, ordinary lime activity is low, its activity is generally within 200ml, mainly for construction and road use, active lime activity, its activity up to 360ml the above. High activity lime high porosity, strong reactivity, low consumption in the process, the process can be controlled, widely used in iron and steel smelting, calcium carbide chemical, power plant desulfurization and other industries.

Active lime rotary kiln consists of cylinder, belting leather, wheel, gear wheel, transmission device, sealing device, cooling device (multi cylinder cooling machine, etc.), the barrel of welding with a brick ring, puzzle with refractory bricks, cold side also welding with retaining ring. According to the different ways of smelting and other kiln type, its structure is not the same, the wet kiln is also linked to the cold end of the chain and other metal heat exchange device or add a slurry evaporator; vertical kiln tail with grate heating machine; suspended preheater kiln tail with a suspension preheating device; vertical cylinder preheater kiln also equipped with cutting the tongue, the other kiln also has a cutting device. The cylinder has a manhole door and is welded with a reinforcing ring to increase the rigidity of the kiln body. The hot end of the kiln is connected with a hood, and the kiln is equipped with a pulverized coal burner. Rotary kiln equipment is a mix of combustion, heat transfer, and reaction heat storage, transmission functions integrated calcination equipment.

With the increasing proportion of fuel costs in lime production, the amount of fuel consumed by calcination lime accounts for 30-40% of the total cost, resulting in a significant decline in profits due to high fuel costs, directly or indirectly affecting coal fuel lime production enterprises profits, so that its survival and development is facing great challenges. Our lime rotary kiln is equipped with vertical preheater and vertical cooling machine, which observably reduce the fuel consumption and energy consumption, so it is wise to choose our company rotary kiln equipment.
