The power consumption of the ball mill was monitored for two months, and the data is shown in the histogram in Figure 2c. It can be seen that the power consumption for each shift varied between 250 and 350 kWh. The dataset is negatively skewed, and the average power consumption for each shift during this period was 294 kWh.
