Ball milling is one of the most common unit operations used for size reduction across a range of industries. However, it is also a notoriously inefficient process, often contributing substantially to operational costs. In this work, we investigate the influence of rotation rate, grinding media fill level and grinding media size on the optimal production of a product of intermediate size. We find that...
Particle size reduction is one of the most widely encountered, yet least energy efficient, processes. Therefore, potentially significant energy and cost savings exist with even the slightest increase in milling efficiency. Often one would like to mill particles to a certain size, and no smaller, while minimizing energy use and milling time. We use the attainable region (AR) analysis to optimize the...
