Chain grate has been used in the domestic cement and metallurgical industries as drying and preheating equipment for many years. With the rapid development of "chain kiln" pelletizing process in my country to produce oxidized pellets, this process has gradually been recognized by the industry. Chain grate is the main equipment for oxidized pellet production. Its functions include green ball drying, partial roasting and rotary kiln roasting.

It can fully dry and preheat the iron ore concentrate block, and by installing the flat material plate, the concentrate raw material is smoothed, so that the iron ore concentrate raw material is heated more evenly and fully, and the folding reciprocating conveying method is adopted to extend the residence time of the iron ore concentrate raw material in the chain grate chamber, so that the concentrate raw material is dried more evenly and thoroughly.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed chain grate for refined iron ore has the following problems: in the above-mentioned technical solution, the refined iron ore raw material is leveled by installing a flat plate, so that the refined iron ore raw material is heated more evenly and fully, but when it is in use, it is impossible to recover the heat carried by the raw material. When the raw material is dried, the high-heat gas mainly comes from the rotary kiln, resulting in the heat in the raw material being wasted. In view of this, a chain grate with dual functions of cooling and drying is provided to overcome the above-mentioned defects. Utility Model Content
