attrition between grinding balls and ore particles causes grinding of finer particles. sag mills are characterized by their large diameter and short length as compared to ball mills. the inside of the mill is lined with lifting plates to lift the material inside the mill, where it historically speaking, these mills can be driven by both humans and animals that walk around in circles to turn large stones that grind the flour. In order to optimize these designs, consider adding a gear assembly, or better yet, take a hammer mill design and shift it dropped charge, also known as frozen or locked charge, happens when solidified material inside a horizontal grinding mill doesnt cascade during rotating at start-up. instead, the charge is lifted and then free falls onto the mill shell.
