The cylinder is the container that holds the ball mill grinding process together. We size cylinders by their total volume when empty. When selecting a cylinder, it's important to pick a size that could potentially hold all of your grinding media, raw materials, and 25% of your total volume for processing space—what we consider the "working" area of the ball mill.
