Rod mills are long cylinders filled with steel rods that grind by compressive forces and abrasion. The length of the cylinder is typically 1.5 to 2.5 times longer than the diameter. As the mill turns, the rods cascade over each other in relatively parallel fashion. One of the primary advantages of a rod mill is that it prevents over-grinding of softer particles because coarser particles act as ...

A hollow shaft is much more weight-efficient so if weight is important then hollow is best. However, if it needs to be very skinny then maybe hollow will not be strong enough. The fact is that for the same diameter shaft the solid shaft will be stronger, heavier, and also resonate at a lower frequency. If you want it to rotate at high speed, then a low resonant frequency could be a problem ...
