这是因为制粒后的烧结混合料里的较大焦粉颗粒燃烧效率更高，制粒效果更好，因而原始料层透气性和烧结透气性更好。
This was due to more efficient combustion of larger coke particles in a granulated mix and also to better granulation and therefore higher green feed permeability and sintering permeability.
提高烧结混合料透气性，对提高烧结机利用系数、降低烧结能耗有着重要的作用。
Increasing the ventilation of sintering mixture is very important for increasing the sinter productivity, decreasing sinter energy consumption.
