运用彩色人工颗粒 ,对不同跳汰周期下中、高密度颗粒在低密度煤炭床层中的沉降速度进行了示踪研究 ,确认长进气期周期有利于中、高密度颗粒与低密度煤炭颗粒的分离。
Using color artificial particles, the sedimentation velocity of medium and high density particles in low density coal bed under different jig cycles was traced. It is confirmed that the period of long aspiration period is favorable for the medium and high density particles and low density coal particles The separation.
