Abstract

This study deals with the grinding of mill scale in a laboratory ball mill for different milling time then briquetted by using 2% molasses as a binder and investigates the effect of grinding of mill scale for different time on the physicochemical properties and the reduction degree of the mill scale briquettes via hydrogen. Diffusion process control equation was applied and the energy of activation was calculated = 28.33 kJ/mole.

Keywords
