One of the most frequently occurring mistakes with conveyor or feeder sizing comes from confusing material usage with instantaneous demand. For example, while a process may consume 1,000 pounds per hour of material, the conveyor or feeder may need to deliver at a rate that is 12 times higher if the batch needs to be satisfied in …
