Material for Coating Iron Ore Pelletizing Disks and Drums and a Constructive Arrangement for Pelletizing Disks and Drums
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 ).
1 . A material for coating iron ore pelletizing disks and drums, characterized by comprising a mixture of binders with ores (that may or not be ground) of the group consisting of iron, manganese or others, that have the same or distinct natures of the material being pelletized.
2 . The material for coating iron ore pelletizing disks and drums according to claim 1 , characterized in that the inclusion of fluxes is also provided.
3 . A constructive arrangement for pelletizing disks and drums, characterized in that the bottom thereof is coated with the material as defined in claim 1 , thus forming a bottom coating layer of a mixture of cold cure materials, vegetal oils, minerals and/or gel-forming products, wherein polyethylene plates can also be incorporated into the inner perimetral edge of said pelletizing disk or drum.
4 . The constructive arrangement for pelletizing disks and drums according to claim 3 , characterized in that the bottom layer of the new material is disposed on the conventional bottom surface itself and/or between a metallic frame or screen and the layer formed by the ore itself, wherein said metallic frame extends throughout the whole area of the circular portion of the disk and is supported by angle bars, as well as other configurations of possible applications.
5 . A constructive arrangement for pelletizing disks and drums, characterized in that the bottom thereof is coated with the material as defined in claim 2 , thus forming a bottom coating layer of a mixture of cold cure materials, vegetal oils, minerals and/or gel-forming products, wherein polyethylene plates can also be incorporated into the inner perimetral edge of said pelletizing disk or drum.
