静态分选的特点是介质运动速度慢，采用较稳定的细粒悬浮液作介质，悬浮液的密度接近于实际分选密度。动态分选的特点是介质受外力作高速回转运动或垂直脉动，采用粗粒的不稳定悬浮液作介质，实际分选密度比给入介质密度大。动态分选可以使用密度较低的加重质，以降低介质的成本。

The static separation is characterized by the slow motion of the medium, and the stability of the suspension medium, and the density of the suspension is close to the actual separation density. The dynamic separation is characterized by high speed rotary motion or vertical fluctuation of the medium, and the coarse grain is used as the medium, the actual separation density is greater than that of the medium density. Dynamic sorting can be used to reduce the cost of the media, which can be used to reduce the cost of the media.
