Satisfactory 7 to 7 load balancer

With 7 input belts of 480/min each (a full Mk4), the build with the best result is the Looped butterfly: 24 splitters and 24 mergers, with 480/min on each of the 7 outputs.

A splitter only divides by 2 and 3, so part of the flow goes back to the input (a loop) to reach this count.

Step by step

1. Bring in the 7 input belts (I1, I2, I3, I4, I5, I6, I7), 480/min each.
2. Column 1: 8 splitters into 2.
3. Column 2: 8 mergers.
4. Column 3: 8 splitters into 2.
5. Column 4: 8 mergers.
6. Column 5: 8 splitters into 2.
7. Column 6: 8 mergers; 1 loop return leaves from here.
8. Connect the 7 outputs to the destination lines: each carries 480/min.

What it is

A load balancer is a set of splitters and mergers that takes N belts and delivers M belts at exactly the same rate, no matter how much each input carries. There is no “balancer” piece in the game: you build it from regular pieces.
