In order to improve the mixing uniformity of plastic particles mixed by ploughshare mixer, the author extracted three structural parameters of the mixing structure and established nine models of orthogonal experiment. Use Discrete element method to simulate the mixing process of polypropylene and polyethylene particles, and take the coefficient of variation as the evaluation index of mixing uniformity. The experimental results showed that the optimal parameter combination is that the intersection angle of side blades is 40°, the circumferential distribution angle is 180°, and the axial distribution spacing is 164mm, when strength and abrasion resistance were verified as acceptable. The research method can provide certain reference for powder &particle material mixing analysis and equipment improvement.
