Single direction non-reversing belt conveyor of reasonable length, may use a standard end drive with the 4" dia. drive pulley. A reversing belt conveyor should use a center drive, generally, with a larger than 4" dia. drive pulley, particularly with longer conveyor lengths or heavy loads on the belt. See the Hytrol General Catalog.

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.
