Kneading machine is an important equipment for the mixing of high viscosity materials.This paper analyzes the planetary gear train transmission system of kneading machine and gives the formulas of propeller rotation and revolving speed. Using Matlab software, the blade trajectory of kneading machine is mathematically constructed by coordinate transformation Mode and numerical simulation. The moving window calculation method is proposed, and the number of trajectories in the mixing area is accurately calculated in a window with a specific area as one of the indexes for judging the mixing uniformity of blades to the slurry, so that the mixing effect is intuitive and quantitative Analysis and assessment.
