重介质浅槽分选机内不同粒径颗粒运动学的数值模拟

Numerical Simulation of Different Size Particles’ Kinematics in Heavy Medium Vessels

为了研究重介质浅槽分选机对不同粒径颗粒的分选效果,用数值模拟技术和DPM模型模拟重介质浅槽分选机内部的颗粒运动,将悬浮液不同水平流进入速度和不同上升流介质速度下重介质浅槽分选机内煤炭颗粒的运动轨迹进行比较,从而得出重介质浅槽分选机内不同粒径颗粒的运动规律。

In order to study the separation effect of heavy medium shallow groove separator for different particle sizes,the particle movement inside the heavy medium shallow groove separator was sim-ulated by numerical simulation technology and DPM model.The trajectories of coal particles in the heavy medium shallow groove separator were compared under different horizontal flow velocity of suspension and different upward flow velocity of medium,so that the motion law of particle size with different trajectories in the heavy medium shallow groove separator were obtained.
