浮选槽中固-液-气三相流中颗粒的速度

Particle Velocity in the Three-phase Flow of Solid-liquid-gas in a Flotation Cell

采用PDA激光流速测试技术 ,在固 -液 -气三相体系中对浮选槽中固体颗粒进行了流速测定 ,获得了固体颗粒的速度分布 ,为矿粒与气泡粘附过程和脱附过程机理的研究提供可靠数据。

PDA laser flow velocity testing technique was used to measure the flow velocity of solid particles in the solid liquid gas three phase system in a flotation cell and obtained the velocity distribution of solid particles so as to provide reliable data for the study on adsorption and deadsoption mechanism of particles onto and off from bubbles.
