FAQs About Conveyor Belt Speed Calculation

What is the standard formula for conveyor belt speed?

The industry standard formula for conveyor belt speed is V (m/s) = (π × Drum Diameter D × Motor Speed n) ÷ (Gear Ratio i × 60 × 1000), where V is the belt speed in m/s, D is the drive drum diameter in mm, n is the motor rated speed in r/min, and i is the total gear ratio of the reducer.

How to calculate conveyor speed from motor RPM?

To calculate conveyor speed from motor RPM, you need to know the drive drum diameter and gearbox ratio. First, calculate the output RPM of the gearbox (motor RPM ÷ gear ratio), then calculate the circumference of the drum (π × diameter), and finally convert the rotational speed to linear speed in m/s, which can be done automatically with this calculator.

What units does this conveyor speed calculator use?

This calculator uses standard industrial units: drum diameter in millimeters (mm), motor speed in revolutions per minute (r/min), gear ratio in multiple, and the final calculation result is belt speed in meters per second (m/s).

What is the difference between theoretical speed and actual conveyor speed?

The calculation result of this tool is the theoretical belt speed. The actual running speed of the conveyor will be affected by mechanical transmission efficiency, belt slip rate, load and other factors. It is recommended to reserve a certain margin in the design according to the actual working conditions.
