Sandustry Toolkit

Gold Line Ratio Calculator

Size a gold line end to end: sand in, water needed, gold out, and what the slag branch adds. Change any rate to match what you measure in your own save.

Read this before you trust a number.

No official throughput rates have been published for Sandustry. Rather than print invented figures, this calculator treats every rate as your input. The defaults are labelled with where they came from — one is a community estimate, the rest are neutral placeholders. The arithmetic is what this tool gives you; the measurements have to come from your save.

Measuring a rate: build the machine, let it run for 60 seconds against a full input, count the output, divide.

Inputs

/s

Not documented Enter what your mining setup produces.

%

Estimate Players report roughly 20–25%. The midpoint is used as a seed, not a measured value.

:1

Not documented 1:1 is a neutral placeholder.

/s

Not documented This is the number that decides your shaker count. Measure the point where yours starts to clog.

Slag branch

:1

Not documented

x

Not documented The press is confirmed to yield "lots of gold and spores", but no rate has been published.

/s

Not documented Feed above this and the press starts missing pieces.

Assumes the slag branch runs at full capacity — every unit of slag is burnt and pressed. If you burn only part of it, scale the slag figures by that fraction.

How the maths works

Nothing here is hidden, so you can check it against your own line:

  • Wet sand/s = sand/s (one unit of sand makes one unit of wet sand)
  • Water/s = sand/s × water per sand
  • Shakers = ceil(wet sand/s ÷ shaker capacity/s)
  • Gold/s from shakers = wet sand/s × gold chance
  • Slag/s = wet sand/s × slag per pass
  • Presses = ceil(slag/s ÷ press capacity/s)
  • Gold/s from slag = slag/s × gold per burnt slag

Machine counts round up, because a fractional machine still clogs. If the calculator says 2.1 shakers, you need three — or you need to throttle the feed, which is usually the better answer. Seestopping shakers and filters clogging.

Why the defaults are mostly blank

Sandustry has not published machine throughput figures, and the demo period did not produce a community consensus set either. Printing confident numbers would make this tool look more useful and be less useful. When Early Access data can be read out of the shipped game files, the confirmed rates will replace these placeholders, and the labels will change from Not documented to Confirmed.
