研制和使用圆筒形泡沫分选机的经验表明：分选机在选矿过程中，不能保证沿给矿线单位负荷稳定。这是因为：分选槽中心与周边的泡沫层的移动速度不等，因而浮选时间各异。由于不能保证稳定的单位负荷，使用这种泡沫分选机，造成有用矿物选矿过程的工艺指标降低’‘’。图1为圆筒 The experience of developing and using cylindrical foam separator shows that the sorter can not guarantee the unit load stability along the feeder line during mineral processing. This is because the moving speed of the center of the sorting tank and the surrounding foam layer are different, and thus the flotation time varies. Because of the inability to guarantee a stable unit load, the use of this foam separator can result in a reduction in process specifications for the beneficiation process. Figure 1 shows the cylinder
