摘要
目的 探究辊式磨粉机皮磨系统工作参数对工艺效果的影响,并进行1B磨制粉过程磨辊工作参数优化。方法 通过Dem离散元软件对磨辊研磨过程进行模拟分析,以齿角、前角、轧距、落料点间距4个因素为变量对取粉率和功耗的影响进行分析,并采用正交试验和矩阵分析法对数值模拟结果进行综合评定。结果 得出1B磨制粉工序中最优参数组合方案为齿角γ=85°,前角α=25°,轧距d=1.5 mm,落料点间距b=0 mm。结论 本文对磨辊研磨过程的仿真分析提供了参考方法,并对辊式磨粉机工作参数的优化设置具有一定的指导意义。
The work aims to explore the effect of working parameters of the leather grinding system of the roller mill on the process efficiency,and optimize the working parameters of the grinding roller in the 1B grinding process.The grinding process of the grinding roller was simulated and analyzed using Dem discrete element software.The effects of four factors,namely tooth angle,front angle,rolling distance,and spacing between feeding points,on the powder extraction rate and power consumption were used as variables for analysis.Orthogonal tests and matrix analysis were used to comprehensively evaluate the numerical simulation results.The optimal parameter combination scheme for 1B grinding powder process was tooth angleγ=85°,front angleα=25°,rolling distance d=1.5 mm,spacing between blanking points b=0 mm.This article provides a method reference for the simulation analysis of the grinding process of the roller mill,and has certain guiding significance for the optimization of working parameters of the roller mill.
