Conveyors are inherently constant torque machines. That means a constant level of torque is required to drive the conveyor regardless of the operating speed. Figure 1 is a typical graph of load torque vs. speed for a conveyor.

So, if conveyor is 80' long and roller spacing is 3' 4", we might expect capacity of up to 96 or 100 CPH. Actual line speed can be calculated by measuring how many seconds it takes roller to move by. For example, if it takes 30 seconds for 8 rollers to move by (3' 4" spacing), conveyor line operating speed would be 120 CPH.

Usually the HP rating of a machine and the speed is known and it is necessary to determine the torque T = 5250.HP/RPM A useful "rule of thumb" to remember is that one HP at 1750 RPM is equivalent to three lb. ft. torque. By ratioing HP and RPM the torque of any motor can be estimated mentally. Translation: HP - Force - Velocity

For modular plastic chain conveyors, a driven transfer can be added to cover the gap and propel product across it. This small roller conveyor is typically powered directly from an output shaft at either the tail or drive end of the conveyor. They run about 10% faster than the actual conveyor speed to ensure product clears the gap.

Conveyor belts on installations, where the belt width is equal or larger than the conveying length, are increasingly difficult to guide. Namely thin belts with little lateral stiffness, particularly at high speed, have a tendency to buckle and potentially fold over when fitted on short conveying distances with cylindrical-conical pulleys.

The way to accurately find the speed of a conveyor is to measure the length then time it for 1 or several rotations. Make a mark "Start" on the belt, measure with a long tape measure to a second point, advance the conveyor then measure from point 2 to a new point 3, and so on until eventually you come back to "start". This is the length.
