The larger the critical diameter of sediment, the smaller the sacle of funnel is applied so as to strengthen the vortex to discharge sediment with less water consumption.
排沙下界粒径较大时，可以选择较小的漏斗尺寸，使涡流强度提高以较小的耗水率排放泥沙。

The bottom of the cathode chamber assumes a funnel shape and is provided with a discharge port.
阴极室底部呈漏斗状， 并设有一出料孔。

This is called a "funnel flow" pattern, in which some material moves while the rest remains stationary during discharge.
