Questions about your line rate
How do I go from tons per hour to boxes per minute?
Boxes per minute = metric tons per hour × 1000 ÷ kilos per box ÷ 60. A line running 5 metric tons per hour with a 25 kg crate receives 3.3 crates per minute if they came one by one: about 200 crates per hour. With an 11.34 kg box it puts out 7.3 boxes per minute.
Why do the infeed rate and the outfeed rate differ?
Because the field crate usually weighs 20 to 25 kg and the outgoing box 4 to 11 kg. At the same tonnage, two or three times as many boxes leave as crates come in, and they also split across several outfeeds by size.
How many people does it take to dump that by hand?
NOM-036 sets a floor: kilos per hour × 8 ÷ 10,000 people per shift, when the load is carried less than 10 meters. At 5 metric tons per hour, at least 4 people.
