Abstract:

The effect of kneading clearance on the mixing performance of vertical kneading mixers was investigated by using the CFD methodsFirstly，the mixing field in the kneading tank was simulated numerically after analyzing the movement of mixer blade and the rheological properties of the materialNext，some macro mixing performance evaluation indices of the device were proposedLastly，the effect of kneading clearance on mixing performance was studiedThe results indicated that a small kneading clearance could improve the mixing performance of vertical kneading mixers and better kneading efficiency could be achieved with a uniform kneading clearance.
