本文从干燥粗粒固体的形状分离出发，分析了椭球体在倾斜静止平板上的单向重力运动，并根据旋转、跳跃和滑动的组合运动计算了颗粒的轨迹。结果，发现更小的、圆形的或更多摩擦的颗粒在一定时间段内有效地通过颗粒旋转而更远地落在更小倾角的板上。因此，在窄范围内的不同形状的多组分颗粒在从倾斜板的底部边缘自由下落之后在横向飞行距离上连续分离是可能的。
With a view to shape separation of dry coarse solids, the gravitational motion of ellipsoids is analyzed in the uni-direction on inclined stationary plates.The particle's path traces are computed on the basis of the combined motion of rotation, jump and slide. As a result, smaller, circular or more frictional particles are found to fall farther down the plate of smaller inclination in a certain time-period, effectively by particle rotation. Thus, it is possible that the multi-component particles of differing shape within the narrow range become separated continuously in the lateral flight distance after free falling from the bottom edge of the inclined plate.
