在详细考察了各品级煤在不同的操作变量条件下的浮选规律的基础上 ,通过多元非线性回归分析 ,建立了各粒度密度级浮选速率常数及水浮选速率常数与操作变量之间的多元的、非线性的、多方程的大系统模型 .以建立的模型为基础 ,采用时间离散化模型方法对连续工业浮选机进行模拟 ,开发研制了浮选仿真系统 ,该系统能够动态显示操作变量的变化情况及浮选产品数质量对操作变量的响应情况
Based on the detailed investigation of the flotation regularity of various grades of coal under different operating variables, the relationship between the flotation rate constants and the flotation rate constants and operating variables of each particle size density grade was established by multivariate nonlinear regression analysis Based on the established model, the time-discrete model method is used to simulate the continuous industrial flotation machine, a flotation simulation system is developed and developed, which can dynamically display Changes in operating variables and the quality of the number of flotation products operating variables response
