Air -blower air flow structure and oxidized pellet's production system

The utility model relates to an air -blower air flow structure and oxidized pellet's production system relates to the metallurgical equipment field. Air -blower air flow structure includes a pluralityof air -blowers, and every air -blower is used for the cooling of pellet through the cold machine intercommunication of its air -out pipeline that corresponds and ring, and every air -blower is equipped with observes the hole, lid that the air -out pipeline was equipped with the through -hole and corresponded with the through -hole, and lid removable cover covers in the through -hole. Including the oxidized pellet's of above -mentioned air -blower air flow structure production system, still including and the cold machine of drying grate, rotary kiln and ring that connects gradually, the air -out pipeline is used for the cooling ball nodulizing with the cold machine intercommunication of ring. Above -mentioned equipment is at the air -blower, can get into quick, safely when bellows break down, and production is el
