球团生产过程中鼓风干燥的作用

The Function of Up-draught Drying in Pelletizing Production

鼓风干燥可避免料层下部生球过湿,提高干燥效率,强化干燥过程进而提高爆裂温度,有利于球团生产的顺行和提高生产率。对生球的干燥机理进行了介绍,并结合实际工程阐述三种主要球团生产工艺中的鼓风干燥行为。

up-draught drying can prevent the green balls at the bottom of material layer not too wet, and improve the drying efficiency. Strengthening drying procedure then increasing the blasting temperature helps the smooth operation of pelletizing production and improve the productivity. The paper introduces the drying mechanism of green ball, and combining the practical projects, it describes the up-drying activity in three main pelletizing process.
