The green pellet making studies was done with the intention of consuming a least amount of binder for getting optimum green pellet strength at minimum possible Blaine number (SSA) . Higher blaine number will translate in to higher energy requirement for grinding [ 10 ]; hence, lower blaine number of iron ore is preferred.
ادامه مطلبUnderstanding Pellets and Pellet Plant Operations. Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.

ادامه مطلبThe various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
