A lot depends on a number of factors here. 1) Is there a gearbox? 2) What is the required torque to rotate this container? Use worst case scenario for calculations. 3) Acceleration and Deceleration times?
Once these three questions can be answered selection of the speed controller and motor can begin.
If there is a gearbox between the motor and the container I suspect a VFD
in closed loop mode and an AC motor might be best or least expensive.
If there is no gearbox and the required torque is not tremendous one might be able to use a Servo motor and controller. This option will require more precise calculations for load and speed.
I would not use a DC motor and controller here. First fairly old technology, second the power factor for DC controller is not great. Third the DC motor requires more maintenance than the AC or servo motor.
I think your best option here is to use a VFD, AC motor with encoder feedback and 40:1 or 50:1 gearbox.
