The ball-to-material ratio is a critical parameter in the ball milling process. Insufficient ball-to-material ratio can lead to an increased buffering effect of the material, thereby weakening the impact grinding action and reducing enzymatic hydrolysis efficiency. Conversely, an excessive ball-to-material ratio can result in unnecessary work ...
