The diameter is large for its large feeding size. Generally, the inner diameter of the hollow shaft is about 2 times of the larger ore feeding size, which is about 0.2-0.3 times of the inner diameter of the ball mill. The short length is for the higher speed of the flow of ore. Internal Structure Comparison

Large grinding equipment is typically split into multiple segments or cans in order to make their manufacturing and transport to a mine site feasible. For example, a large 40 foot diameter SAG mill without liners weighs in excess of 3.6 million lbs (1.6 million kg), making it impossible to make, ship, or lift this equipment in one piece.
