摘要
为了筛分性能的良好 ,采用了第 1临界速度的概念。根据确定的第 1临界速度获得弛张筛筛面的转角速度 ,从抛掷指数和节能的角度来观察所选转角的合适性 ,最终确定转速为 5 2 0r min。
For optimizing screen's characteristic,the first critical velocity is used.By the first critical velocity of flip-flow screen,we got the revolution speed.Then we have praised the appropriate of the revolution frequency on the light of Kv and energy and made a conclusion that the frequency should be 520 r/min.
