Optimization of mill performance by using

2015-4-16  Optimization of mill performance by using online ball and pulp measurements In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs. (Figure 7.)

Optimization of Feed Rate in Cement Grinding Mill Using

2015-5-20  The block diagram of the proposed system is shown in figure 2 which shows the PID control structure with CMAC parameter optimization. The block diagram consist of cement grinding mill, sound sensor(microphone), audio signal converter, CMAC neural network, PID controller and motor in weigh feeder. The comparator generates an error signal by comparing input sound signal with feedback signal from sensor. According to the error signal, PID controller gives a signal to control the feedrate input to grinding mill through weigh feeder. Weigh feeder is used to increase (or) decrease the feed flow rate. The sound level of grinding process is sensed in decibels by microphone and audio signal converter converts that to an electrical signal. An intelligent CMAC algorithm is used to tune the parameters of PID controller to optimize

The mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the material’s grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor

SAG Mill Optimization using Model Predictive Control

Semi-Autogenous Grinding mills can be optimized for maximum ore throughput or maximum grinding energy efficiency. In both cases, precise control of the mill weight is critical. Model predictive control provides an additional tool to improve the control of Semi-Autogenous Grinding mills and is often able to reduce process variability beyond the best performance that can be obtained with proportional-integral-derivative or expert system control methods. Model predictive control is able to optimize the control of processes that exhibit an integrating type response in combination with transport delays or variable interaction, which are characteristic of the Semi-Autogenous Grinding mill
