The mechanism of this instability is based on the cycle of acoustic waves between their corotation radius and the shock.
这种不稳定性的机制是基于声波在其同心圆半径和冲击之间的循环。

The corotation ladder-shaped cover nut is enclasping central tube, and easy to realize rapid dismantling.
正旋梯形螺母即抱紧中心管，实现快速联接和密封。

The unit is mix the moist powder into machine. Under the action of corotation & reversal revolving roller, It is a special pelletizer equipment by force screen cloth.
