AI Technical Summary
Existing technologies for preparing oxidized pellets have difficulty utilizing the poor pelletizing and roasting properties of iron-containing raw materials, leading to increased production costs and equipment investment. Furthermore, existing pretreatment methods are inefficient.
Difficult-to-utilize iron-containing raw materials are divided into specular hematite concentrate, coarse-grained iron concentrate, and ultrafine-grained iron concentrate. Each concentrate is modified by spraying binder and activator solutions. Through pelletizing, drying, preheating, and roasting processes, high-strength oxidized pellets are formed.
It improves the pelletizing and roasting properties of difficult-to-utilize iron-containing raw materials, enhances the quality of pellets, reduces production costs, and achieves high-efficiency utilization without the need for additional equipment investment.
