Sandustry Logistics: Conveyor Belts, Launchers, and Filters

Your production chain is only as good as the pixels that reach the next machine. Conveyor Belts are the horizontal workhorses, Launchers are how you fight gravity, and Filters are how you split a mixed stream. Learn the rules once and the same three parts solve most factory problems.

The three parts and their rules

  • Conveyor Belt: moves solids sideways, and blocks liquids, gases, and players
  • Launcher: lifts solids straight up a tower, and lets everything pass through it
  • Filter: works like a belt but only lets chosen elements cross (Tier 1, 250 Gold)
  • Hold Shift while placing a belt to reverse its direction

Route Material Step by Step

Most layouts are just these three pieces arranged in a loop: belt the material sideways, launch it upward, filter what should and should not continue.

Step 1

Conveyor Belt moves solids sideways

A belt has no throughput cap: it advances as many pixels as the space ahead allows. Only the layer directly on the surface is driven; anything stacked above just rides along on top of it. If the leading pixel is stuck, the entire pile holds still rather than flowing over the blockage.

Checkpoint: a pile on the belt advances exactly as far as the clear space ahead of it.

Step 2

Launcher fights gravity

A Launcher pushes solid pixels upward. Reaching the far end, they coast a short way past it, drop back onto the machine, and bob on its top while they wait for a way out. Angle the top Launcher of a tower and the pixels fire out to whichever side it faces, turning a straight column into a vertical lift.

Checkpoint: pixels rise up the column and fire out the angled top in the direction it faces.

Step 3

Filter splits a mixed stream

The Filter behaves like a Conveyor Belt with one extra rule: it only lets the elements you specify continue past it. When a single line carries several solids, a Filter is what stops them from piling up at the wrong machine.

Checkpoint: chosen elements pass the Filter while everything else stops at it.

Step 4

What each one blocks

A Conveyor Belt seals out liquids, gases, and the player, so it can double as a wall. A Launcher blocks none of them, so liquids and gases flow straight through it. That difference decides which one you use when a line has to cross a reservoir.

Checkpoint: a line that needs to cross a reservoir uses a Launcher, not a belt that would seal it.

Design rules

How to place each one well

  • Hold Shift while placing a belt to reverse its travel direction
  • Stack Launchers in a column, angling only the top one to unload sideways
  • Rows of angled Launchers move pixels horizontally in a hurry
  • Launchers sample their tile on an interval, so a pixel that has just landed is not always picked up immediately
Conveyor vs Launcher

Pick the right tool

  • Liquids ignore a belt's direction and flow as if it were ordinary ground
  • Use a Launcher when material needs to rise; use a belt when it needs to travel flat
  • Use a belt as a wall; use a Launcher where liquids and gases need to pass
  • Use a Filter when two solids share one line and should not arrive together

Where Logistics Fits Your Factory

Logistics is not a late-game luxury. It is the research that turns the manual hauling of the opening minutes into a line that runs while you dig.

Unlock it early

Logistics costs only 30 Gold

The Logistics research node unlocks both the Conveyor Belt and the Launcher in one purchase, and it sits right next to the Shaker in Tier 1. It is the cheapest automation step in the entire tree.

Wire it into Gold

Automate the sand line

Belt the Wet Sand toward your Shaker staircase, launch material out of pits, and the first Gold line stops needing your hands on every single pixel.

When it clogs

Diagnose a stalled line

A blocked bottom pixel can stop an entire pile on a belt. If material backs up, the cause is usually a jam at the front of the line, not a broken belt.

When the Line Stalls

Four common logistics failures, each paired with the mover rule behind it and the fix that uses the right part.

Belt jam

Material backs up and the whole pile holds still

A blocked leading pixel stops the entire heap, because a belt only drives the surface layer and nothing flows over the blockage. Clear the jam at the front of the line; the belt is not broken.

Launcher lag

A freshly landed pixel is not picked up

Launchers sample their tile on an interval, so a pixel that has just dropped in can sit for a moment. Give it a beat or nudge the pixel back onto the tile instead of rebuilding the machine.

Wrong tool across water

A belt sealed off a flow that needed to pass

A Conveyor Belt blocks liquids and gases, so across a reservoir it acts as a wall. Swap for a Launcher, which lets liquids and gases flow straight through.

Mixed stream

Two solids arrive at the wrong machine together

When one line carries several solids and nothing splits them, they pile up at the first machine the stream reaches. Insert a Filter set to the element you want to continue.

Where to Go Next

The three movers each have a deeper mechanics page that covers the full rules behind the steps above.

Core logistics rule

Most early logistics failures make sense once you separate three jobs clearly: belts move solids sideways, launchers lift them through space, and filters split mixed lines.

What still depends on terrain

Exact route shape, final throughput, and which mover feels best still depend on map geometry, elevation, and what else must cross the same space.

Featured Questions

How do logistics work in Sandustry?

Conveyor Belts move solids sideways, Launchers lift them vertically, and Filters separate mixed streams by allowing only chosen elements through.

When should I use a Launcher instead of a Conveyor Belt?

Use a Launcher when material must rise or when liquids and gases need to pass through the same space. Belts are better for flat solid transport and wall-like separation.

Why does my logistics line stall even if the belt is placed correctly?

The usual cause is a blocked front pixel, wrong receiving tile, or mixed materials arriving together without a Filter.
