When it is used between ball mill mated with magnetic liner and classifier, the underflow ratio and grinding efficiency are increased.
应用于使用磁性衬板的球磨机与分级机之间，可提高返砂比和磨矿效率。
The analysis includes the concentration ratio at the base of a GCL, advective and diffusive mass flux, and total accumulated contaminant mass through the liner per unit area.
从衬垫底部浓度比、对流和扩散通量、污染物累积运移量等方面，对污染物在GCL中的运移进行了计算。
It shows that with the increasing of curvature radius, liner thickness, the length-to-diameter ratio of the charge, and decreasing of shell thickness, the velocity of EFP increase.
结果表明：随着药型罩曲率半径、装药长径比、壳体厚度的增大以及药型罩壁厚减少，EFP的速度增大。
