The standard speed for most unit handling conveyors is 65 FPM (feet per minute) which works out to the average speed a person walks when carrying a 50-pound box. This pace is ideal for many—but not all—order picking and assembly operations. There are always situations where transport through an area, into a process, or toward a packing operation can be accelerated.

The Speed of a Belt calculator computes the speed at which a linear length of belt travels around a pulley based on the diameter (D) of the pulley and the rotation rate (R).Belt INSTRUCTIONS: Choose units and enter the following: (D) Diameter of the pulley (RPM) Rotation Rate of the pulley Belt Speed (BS): The calculator computes the belt speed (BS) in meters per second.
