Abstract: The lifting flight on traditional rotary drum dryer has the disadvantage of missing the rotary drum when scattering material plus unreasonable scattering. The three-arc lifting flight, a product yielded from the marriage between mechanical theories and experiments overcomes these drawbacks. Moreover it enjoys high packed percentage. This new type of lifting flight is remarkable energy when used for industrial production.

摘要： 现有转筒烘干机的抄板不能把料撒在整个转筒内 ,而且撒料也不合理 .用力学理论和实验结合得出的三弧抄板克服了这些缺点 ,并且填充率高 (>2 0 % ) .如果用于工业生产 ,必将有显著的节能效果 .
