以回路模拟作为最优化模型,研究了磨矿回路离线最优化程序。用一个转换方程使可控变数维持在上下限之间。补偿函数阻止了旋流器的绳状排料和磨机过载。本研究之目的在于在给定的旋流器数目下,找出一组可控变数,使旋流器的溢流粒度维持在+48目占20％。可以看出,在回路限定范围内,使用4,5,6,7,个旋流器可以达到这一目的。 Taking loop simulation as the optimization model, the offline optimization program of grinding circuit was studied. Use a conversion equation to maintain controllable variables between the upper and lower limits. The compensation function prevents the swirler rope discharge and the mill overload. The purpose of this study was to find a set of controllable variables for a given number of cyclones so that the overflow particle size of the cyclone was maintained at +48 mesh (20%). It can be seen that in the loop limited range, the use of 4,5,6,7 cyclone can achieve this goal.
