Influence of Grinding Ball?Motion Behavior on Particle Crushing Performance and a Way of Micro?particle Preparation in a Flutter Ball Mill
摘要
Abstract
Motion behavior of grinding balls plays a vital role in improving efficiency of particle crushing. A method of preparing micro-particles by changing ball-motion behavior in a flutter mill is proposed and multiple grinding experiments are conducted. Crushing performance parameters,such as breakage rate Si,production rates of fine particles Fi and Fi*,are studied in different motion conditions. From the results,a better crushing performance is attained in the coupled motion modes of rotating speed ratio of 85％,with a vibrating amplitude of 8 mm and a frequency of 12 Hz. In addition,the influence of ball-motion behavior on particle crushing performance is discussed. The ball-motion behaviors,such as the collision energy loss E,among grinding balls have some relationship with the particle crushing performance of Si. Therefore,this study not just provides an efficiency way of accumulating micro-particles,but also reveals how the ball-motion behavior influence particle crushing performance in the flutter mill.关键词
