The invention is directed to a material for coating iron ore pelletizing disks and drums and a constructive arrangement for pelletizing disks and drums that is comprised of a mixture of binders with ores (that may or not be ground) of the group consisting of iron, manganese or others, the inclusion of fluxes being also provided. The bottom ( 1 ) of the disk or drum ( 5 ) is coated with a cold cure coating material, vegetal oils, minerals and/or gel-forming products in order to form a bottom layer ( 2 ) that may or not be on the surface, and polyethylene plates ( 7 ) to aid in the separation of the fines from the pellets ( 6 ) can also be incorporated into the inner perimetral edge ( 6 ) of said pelletizing disk or drum ( 5 ).
