Apr 09, 2015nbsp018332the 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 quotstartquot 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 quotstartquot.
If you need more accurate then you need a feedback device on the conveyor, which also needs its output scaled to the actual conveyor speed. spend all day calculating these numbers and then you will find out that the motor does not go 1725 rpms at 60hz and the gear reduction is not nominal and the belt on the conveyor slips etc etc etc.

Belt widths the belt widths are as follows 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. the width of the narrower belts may be governed by the size of lumps to be handled. belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

A 60 foot long conveyor with a speed of 60 feet per minute will always be completely full and have zero room for buffering. double the conveyor speed from 60 fpm to 120 fpm, and the result provides enough space on that same conveyor to accumulate 30 products at any given time which will create efficiencies with downstream equipment.
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
