In the grate kiln process, a chain grate system is used for drying & pre-heating the green balls to be fed into the rotary kiln, where they are indurated. The pellets are finally cooled in a circular cooler. Iron ore pellets are being increasingly favoured in modern blast furnaces.
Tunnel Kiln history dates back to 1807 when Hoganas first used this process to produce iron powder of 99.9% purity. When iron ore is mined or processed (in a crusher), lots of fines are generated. Quantity of fines generation is a function of the quality of ore i.e. whether it is hard or soft.
Wind Tunnel ... Whether using the straight grate process or adding a rotary kiln to make the grate-kiln process, our products play a key role. To dry and heat the ore pellets, a number of fans are used to recycle heat from the kiln. After indurating in the kiln, cooling fans are used to cool the pellets for handling downstream, and fans are ...
