Description
technical field [0001] The invention relates to the field of mineral powder pellet smelting, in particular to a new process and equipment for processing mineral powder pellets in a smelter. Background technique [0002] Pelletizing is one of the important methods of fine ore agglomeration. Add appropriate amount of water and binder to the powdered ore to make green balls with uniform viscosity and sufficient strength. After drying and preheating, they are roasted in an oxidizing atmosphere to make the green balls agglomerate and make pellets. This method is especially suitable for processing fine ore concentrates. [0003] However, fine-grained concentrates must be pelletized before they can be used as raw materials for metal smelting. The pelletizing process is very complicated. Although it has undergone many process optimizations, it is still a process that consumes a lot of energy and pollutes heavily in the metallurgical process. Therefore, those skilled in the art pr...
