摘　　要：FJCA型煤用喷射式浮选机将倒梯形槽体断面改为矩形槽体断面,增加了槽深,提高了泡沫区和浮选区的高度;减小了槽宽,从而缩短了泡沫层水平运动的距离,成倍提高槽底充气均匀程度,浮选完善指标显著提高。The cross-sectional shape of FJCA jet flotation machine for coal was changed from inverted trapezoid to rectangular,cell depth thus increased,both height of froth and flotation zone elevated; cell width decreased,leading to reduction of horizontal moving distance of forth layer,even degree of aeration at cell bottom increased by times,and the perfection index of flotation remarkably upgraded.
