Apr 09 2015 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.

With the frequency converter for driving belt conveyor the synchronous control of torque and speed for the belt-drive unit can be achieved and the start-up characteristics of belt conveyor can also be improved. This paper uses two methods for achieving synchronous drive of belt conveyor one is synchronization through master-slave control of frequency converter itself the second is adding.

High speed roller conveyor systems driven by notch belts to control high-speed acceleration and deceleration. This high speed conveyor is often used as an accumulating conveyor before a stacking or packing machine. Furthermore it is suitable for high speed applications where e.g. servo drive is necessary to control the speed of the conveyor.

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.
