Horse power needed to turn a 22" dia X 31" tall cylinder weighing about 250lbs @ 500 to 1500 Rpm

I have a project that I need some help with (outside my area of expertise)

My quandary is how much Horse power is needed to turn a 22" dia X 31' tall cylinder weighing about 250lbs, 500 to 1500 Rpm (variable speed) has roller bearings on bottom, ball on top of shaft.(spins freely)

Seems to be maxing out the capabilities of a 2.5 HP treadmill motor.

Any and all assistance appreciated.

Hi
Could you please tell us what load you expect? If the cylinder is balanced, it will require very little HP to maintain the speed. I assume that that the cylinder does something like tumbling or mixing some sort of material. Please expand your description of the machine then we will be better able to help.
