Adjusting mill parameters: Fine-tuning mill parameters such as mill speed, ball charge, filling ratio, and grinding media size can have a substantial impact on the grinding efficiency of the mill. For example, a 10% increase in mill speed can result in up to 10% higher production rate, while optimizing the ball charge can lead to a 5-10% reduction in energy consumption.
