Energy-saving annular lime kilns manufacturer

Advantages of an Annular Shaft Kiln are lower thermal loss, higher activity of
lime, simpler structure and greater fuel adaptability compared with a traditional
lime kiln. Lumpy materials such as limestone are going to be calcined and sintered
in the annular space with uniformity of air flow distribution There are no cooling
units in the kiln, fault rate therefore could be fairly Iow and easy to maintain.
The Annular Shaft Kilns are widely applied in iron industry to manufacture high
quality lime with coke-oven gas or in chemical industry with calcium carbide
furnace gas as its fuel.Technica Fetures:1. Production Capacity: 150t/d, 300t/d,
500t/d, 600t/d four diferent standards of annularshaft kilns can be designed and
manufactured by XinHua. Production capacity can beregulated within a certain limits
without compromising quality and consumption rates.2. Grain Size: 20-100mm, scale
factor 1:33. Fuel type: natural gas, coke oven gas, calcium carbide furnace gas,
oil.4. Lime: with up to 1.5% C02 remains(24 hours average value), activity is
greater than 360ml(4N, HCL method 10 mins).5. Thermal loss: with the maximum limits
use of thermal energy, abstracted heat air from cooling lime and inner shaft and
partially exhaust gas generated from combustion aretransferred into calcining zone
by an ejector. Under normal situations, the thermal loss can becontrolled within
930kcal/kg.6. OperabBty: 48 weeks consecutively.7. Methods of calcining: a combined
method of countercurrent and cocurrent calcining can prevent lime from overburning,
ensure that the lime is fully decomposed and dramatically improve the activity of
lime.
