Abstract

The shape of the blades of the horizontal agitating ball mill will greatly affect the efficiency of the ball mill. In this article, by bending the end of the mixing blade, using discrete element method and EDEM simulation to study the effect of blade bending angle on the efficiency of ball milling. In this article, the degrees of blade bending are 0 degrees, 3 degrees, 5 degrees, and 10 degrees respectively, and the main technical parameters of powder force between particles, particle accumulation, and energy utilization are selected as the main technical parameters for analysis. The research results show that when the blade bending design is 5°, the powder accumulation rate is reduced by 32.48%, the energy consumption of the stirring shaft is reduced by 14.45%, the powder crushing energy utilization rate is increased by 3.47%, and the ball milling crushing effect is the best good.

摘要

卧式搅拌球磨机叶片的形状会极大地影响球磨机的效率。本文通过弯曲搅拌叶片端部，采用离散元法和EDEM仿真研究叶片弯曲角度对球磨效率的影响。本文叶片弯曲度数分别为0度、3度、5度、10度，选取颗粒间粉力、颗粒堆积、能量利用等主要技术参数作为主要技术参数进行分析. 研究结果表明，当叶片弯曲设计为5°时，积粉率降低32.48%，搅拌轴能耗降低14.45%，粉体破碎能量利用率提高3.47%，
