Limestone is used as a fluxing agent and to get strength to the pellet by heat hardening. Coke dust is used as a compensatory fuel and to improve physical strength of the pellets by uniform firing of each pellet up to the core. Both limestone and coke are ground in a definite lime to coke ratio in a ball mill by dry grinding process.
