rotating conveyor belt

[Lalitp]

I want to design a continuous rotating conveyor belt which have a speed of 2mm/sec.
What hardware will required.?
Motor type.?
Gears.?
Any mathematics.?

Only one side will be a motor, other side will be only simple rotor.
I want to save myself from programming..

The power rating of the motor will depend on the size and load on the belt.

For a slow belt speed, you may get by with a small motor running at high speed. Use a large gear ratio. The gearing amplifies torque while it steps down speed.

The motor drives one gear on one roller at one end of the belt loop. All other rollers can be idlers.
