衬板的设计参数对球磨机磨矿效果的影响（Influence of design parameters of liner on grinding efficiency of ball mill） The thirty-eighth volume in 2010 ninth The design parameters of ball mill lining plate Effect of grinding effect * * * Tian Qiujuan Wan Jun 1 2 1 Hao Deng Li Ying Zhang Ruilin 2 Li Chunyu 3 1 Mechanical Science and engineering Jilin University Jilin 130022 Changchun 2 North Heavy Industry Group Co. 3 Changchun Vocational Institute of Technology Abstract: the ball mill Phi 5.5 m * 8.5 m as the research object, research the lining plate angle, height and using three-dimensional discrete element software EDEM Influence of the number of design parameters on energy distribution and impact power of ball mill. The results showed that these parameters in different degree of impact energy The amount of distribution; and from the single particle forces studied the impact angle liner crushing effect of particles. Keywords: ball mill lining plate; design parameters; grinding; discrete element method CLC number: TD453 document code: A article number: 1001-3954 (2010) 09-0073-04 Effect of liner design parameters on grinding efficiency of ball mill TIAN Qiujuan1 HAO Wanjun1 DENG Liying2 ZHANG Ruilin2 LI Chunyu3 1College of Mechanical Science and Engineering, Jilin University, Changchun 130022, Jilin, China 2Northern Heavy Industries Group Co., Ltd. 3Changchun Vocational Institue of Technology Abstract:The paper uses 3-D discrete element analysis software EDEM to analyse the effects of parameters Such as liner obliquity, height and number on the power and impact energy distribution of a 5.5m * 8.5 M Ball mill. The results show that these parameters affect the impact energy distribution in various degrees. It also Studies the effect of liner obliquity on grinding efficiency based on simulating the resultant force applied to a Single particle in ball mill.
