optimizing the control system of cement milling - SciELObetween the process and control variables, with some similarities with the one of Van Breusegem et al. (1994). The derived dynamical parameters were used to parameterize PID controllers between the recycle elevator power and the mill feed flow rate. (Tsamatsoulis, 2009; Tsamatsoulis and Lungoci,. 2010). The objective.ball mill feed control using electric ear,Grinding Mill Control - Grinding & Classification Circuits .Apr 4, 2018 . There were some good correlations, but not reliable enough to use mill control. In one 36 ft SAG we used load cells for weight control (to adjust speed), with feed rate control and power control were used in conduction with the speed control. Worked excellent. There was an AMIRA project to develop some.
