Of Coke Breeze Sintering Iron Ore

What is a Coal Coke Breeze? - Definition from Corrosionpedia

Coal coke breeze is a common backfill material used in cathodic protection. It is a type 1 carbonaceous backfill material. Coal coke breeze backfill has low resistivity and low ash content, and may be treated by the addition of 10% (by weight) commercial grade slaked lime. The fuel used in the iron ore sintering processes is coke breeze.

Sinter Plant | Industrial Efficiency Technology & Measures

The purpose of the sinter plant is to process fine grained raw materials into a coarse grained iron ore sinter, ready to be charged to the blast furnace. Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier. A high quality sinter has high reducability, which reduces the intensity of blast furnace .
