The explanation is shown graphically on another reference in the shrouded turbine thread, but basically the PEPA throws out a thin plane of mixed materials from above and below by centrifugal force. The ejected fluid, when it hits the edge of the beaker at a perpendicular can go up or down and then, reaching the top or bottom it curls around forming two cylindrical mix patters of random fully mixed materials. In doing so, it works in a much smoother method with higher energy transfer and at higher speeds for faster maxing.

According to my translation, you mean "ranbo" or violence!
