Designed for use before the inputs of a storage sorting system consisting of 2 Mk5 belts for a total throughput of 1560 items per minute.

This load balancer allows up to 6 incoming supply lines (from station, truck station, factory etc) to be evenly balanced to 2 Mk5 belts to lead into the sorting system.

I recommend adding industrial storage containers to each input to allow for temporary overloading should you happen to be using trains to deliver items into the sorter (if several trains arrive at once, the input lines could potentially be fed over the 1560 maximum threshold temporarily)

Diagrams of this setup and for a companion sorting system can be found here: https://imgur.com/a/Uy3S0dT
