With Reasonable Design and Special Oxidation-reduction Principle
Sponge iron is a high-quality ore. It is eliminated by the principle of redox reaction and filtered by sediment removal. The dissolved oxygen content of pipes, boilers and circulating water can reach a reasonable value after water treatment. 

Flexible Heat Source Option
In sponge iron rotary kilns, shaft furnaces or other reactors, using coal, coke, natural gas or hydrogen, the iron ore or iron concentrate pellets are reduced at a low temperature below the melting temperature of the material and become porous product.  

Superior in Terms of Environment Protection and Capacity
In sponge iron rotary kiln, vertical furnace and other reactor, iron ore and other iron ore concentrates are reduced in low temperature condition and becomes final products with multiple holes.

Hold Special Calcining Structure
Taeda sponge iron kiln holds reliable seal structure, high mechanical performance, stable transmission, convenient operation and good calcining quality.

Sponge iron in rotary kiln moves from top to bottom, which includes the movement of the upper sponge iron caused by the volume contraction of the sponge iron during the calcination process and the whole kiln sponge iron caused by the discharge of the lower sponge iron. sports. If the sponge iron rotary kiln has a suitable expansion port, the effect of shrinkage on the decline of the sponge iron is very small. Therefore, the moving speed of sponge iron in the kiln is mainly determined by the amount of clinker discharged, which is the output. However, the movement speed of sponge iron must be adapted to the calcination speed of sponge iron, and the calcination speed is related to factors such as calcination temperature, gas velocity, heat transfer, sponge iron particle size, combustion particle size and other factors. The moving speed of sponge iron in the equipment varies with different situations, and its moving speed is related to exhaust air, kiln speed, resistance in the kiln, physical properties of materials, kiln diameter and heat exchange device in the kiln.
