Quick Guide
  • Sandustry compressor setups work best when residue is burned before routing it onward.
  • Burner belts help remove residue without mixing it into the main gold line.
  • Filters and sorters separate gold from seed and other materials.
  • Heat management prevents processing slowdowns and production backups.
  • Expandable layouts leave room for collectors, lifts, belts, and later automation.

Sandustry compressor workflow and core layout

The Sandustry compressor belongs in a production chain that prepares residue, controls heat, and moves processed materials toward collection. The most reliable approach is to separate the factory into clear stages instead of sending every material through one crowded belt network.

A practical early layout usually contains four zones:

  • Excavation and lifts for moving sand or wet sand upward.
  • Processing equipment for turning suitable sand into gold.
  • A residue treatment line using heat or a burner belt.
  • Filters, sorters, and collectors for separating finished materials.

The main lesson is simple: do not treat residue like ordinary gold-bearing sand. The production line described in current gameplay uses burning to remove or transform residue before the material is routed through later machinery. Keeping that operation separate makes the factory easier to inspect and reduces blockages.

Video Highlights:

  • Residue can be burned before entering a more organized processing line.
  • Longer belts and additional presses help increase throughput.
  • Filters can separate gold from seed and other materials.
  • Heat, water, steam, and snow all affect factory stability.

Input Control

Keep excavation outputs aligned with lifts and belts. Remove loose dirt that causes falling materials to stall.

Residue Treatment

Use heat and burning before routing residue into the next production stage. Avoid mixing untreated residue with gold.

Output Collection

Place collectors after filtering so gold does not share the same destination as seed or unwanted materials.

Layout Tip

Build the compressor line with one-way movement in mind. A clean input path, separate residue path, and dedicated gold output are easier to expand than a compact but tangled design.

Preparing residue before the compressor

Residue is one of the main reasons a processing line can become difficult to manage. Untreated slag or residue may not belong directly on the same route as gold-bearing sand. Instead, use a dedicated heat stage and give the material enough space to move through the system.

The burner belt is especially useful once unlocked. It provides a more structured way to burn residue than repeatedly handling small patches manually. A thermal buffer can also help maintain temperature, but it must be placed and connected carefully. Heat values can fall when the line runs for a while, so inspect the system before assuming a belt or press has stopped working.

Residue or slagBurn before further routingMixed into the gold line
Wet sandSend through the normal processing routeSlow movement or insufficient belt length

SteamMonitor separately from waterSmall pockets become difficult to recover

Burner belt sequence

1

Create a separate residue route

Place a belt or controlled path beneath the residue output. Keep it away from the gold collector so unwanted material does not enter the final storage area.

2

Add the burner stage

Unlock and place the burner belt when available. Route residue across the heated section instead of feeding raw residue directly into the compressor path.

3

Stabilize the temperature

Use thermal buffers or nearby heat sources when the line needs sustained heat. Check the displayed temperature after the system has processed material for a while.

4

Inspect the output

Confirm that residue is no longer blocking the route and that gold-bearing material continues toward the filter or collector.

A common mistake is building the burner line too close to a wall, slope, or occupied tile. Falling materials can catch on small pieces of dirt or uneven geometry. If the compressor seems inactive, inspect the spaces above and below the belt before rebuilding the entire factory.

The game also uses water, steam, snow, and heat as connected systems. Steam may rise or condense depending on the surrounding setup, while snow can freeze water or become part of a later water-management strategy. These interactions can affect the available workspace around a compressor line.

Residue Warning

Do not assume every brown material is the same. Dirt and wet sand can look similar, and a single leftover tile may cause falling material to stall above the compressor route.

Filters, sorters, and compressor output control

Once the residue stage is stable, focus on output control. A compressor layout becomes much easier to operate when gold, seed, and other materials each have a defined destination.

Filters are useful because they can be configured for a specific element. A gold filter can direct gold toward a collector while allowing other materials to continue along a different route. This is more reliable than placing multiple collectors without controlling what enters them.

ComponentBest placementFunction
FilterBefore the gold collectorSends a chosen material to a dedicated route
SorterOn a branch lineSeparates material based on configured settings
CollectorAt the end of a filtered routeStores or gathers the desired output
GrabberNear loose ground materialMoves items that belts cannot collect efficiently
Sweeper droneOver an accessible cleanup areaCollects scattered ground materials

Recommended output pattern

Use the following structure when the factory begins producing multiple outputs:

  1. Move processed material onto a main belt.
  2. Place a filter configured for gold.
  3. Send gold toward a dedicated collector.
  4. Route seed and remaining materials to a secondary area.
  5. Keep the secondary area expandable for planters or future machines.

Seed should not be treated as useless waste. Once planter boxes are available, wet seed can grow into flowers that yield gold and amethyllis when harvested. This creates a second production concern: the seed line needs storage, spacing, and a possible harvesting route.

Automatic flower harvesting may not be obvious in the early setup. Until a suitable method is available, leave enough room around planter boxes for manual collection and future automation. A cramped seed output can become a larger problem than the original residue line.

Gold Route

Configure a filter for gold and send the result into collectors. This keeps the primary currency path visible.

Seed Route

Give wet seed its own destination. Planter boxes need space and should not block the main belt.

Residue Route

Burn residue before it reaches sensitive sorting equipment. Keep this branch easy to inspect.

Cleanup Route

Use grabbers or drones for scattered materials that do not flow cleanly through belts.

Efficiency Check

A successful output layout has separate destinations for gold, seed, and residue. If one collector receives several unrelated materials, add a filter or branch before increasing production.

Water, steam, and heat troubleshooting

Resource processing depends on more than belts and machines. Water, steam, snow, and temperature can determine whether the compressor line continues running or begins to back up.

Small patches of water or steam can be difficult to recover, particularly when they settle in awkward spaces. Place pumps and fluid-related equipment where the surrounding terrain leaves room for collection. If steam becomes trapped, inspect the latest available game updates and tools, since the developer has indicated that steam recovery and future condensation options are part of ongoing development.

Heat management principles

  • Check temperature before adding more machines.
  • Keep thermal equipment accessible for inspection.
  • Avoid placing water directly where it can interfere with heated machinery.
  • Use spare space for future buffers, belts, or fluid control.
  • If the line stops, inspect material movement before spending research points.

The factory can also benefit from controlled water production. Later technology may provide more reliable ways to create or condense water, but the exact behavior depends on the current game build. Treat water as a production resource rather than assuming the map will provide an unlimited supply.

Cryoblast-related progression introduces additional interactions with snow, water, lava, and steam. Snow can freeze water, while heat can change the state of nearby materials. These systems are useful for solving environmental problems, but they can also create new blockages when added directly beside the compressor line.

Troubleshooting Order

When production stops, check the input, belt path, heat level, filter setting, and collector capacity in that order. This avoids rebuilding a working machine because of a single blocked tile.

Compressor upgrade checklist and long-term planning

A strong compressor factory is not just a machine placed beside a belt. It is a layout that can accept new research, additional processing capacity, and improved resource collection without requiring a complete rebuild.

The research tree includes tools and upgrades that change how materials are moved and processed. Conveyor portals can shorten transport routes, sweeper drones can collect loose materials, and distance-digging tools can improve access to awkward areas. Prioritize upgrades according to the current bottleneck rather than buying every option immediately.

Compressor Setup Checklist:

  • Create a dedicated input path for sand or wet sand
  • Separate residue from gold before final collection
  • Unlock and connect a burner belt when available
  • Configure a gold filter before the collector
  • Reserve space for seed, planter boxes, and future upgrades

Distance-digging toolRock or distant tiles limit accessExpands safe working range

Use the following maintenance routine after each major expansion:

  • Watch the line for several processing cycles.
  • Confirm that gold reaches the correct collector.
  • Check whether seed is accumulating in a safe location.
  • Inspect the burner temperature.
  • Remove isolated dirt or sand that catches falling materials.
  • Leave room around new machines before adding another branch.

The community discussion also highlights several quality-of-life concerns, including trapped water or steam, limited early automation, and difficulty finding an automatic flower-harvesting solution. These are useful planning signals: keep fluid spaces accessible, avoid overfilling storage, and do not design the factory around a harvesting method that has not been confirmed in the current build.

Expansion Tip

Leave at least one open side beside the compressor route. Future belts, portals, buffers, drones, or fluid tools may need more space than the first version of the factory suggests.

Q: What should enter the Sandustry compressor line first?

Use a controlled input of sand or wet sand, while keeping untreated residue on a separate route. Residue should pass through a heat or burner stage before it joins later processing.

Q: Why does residue block my production line?

The burner stage may be missing, disconnected, or too cool. A leftover dirt tile, slope, occupied cell, or crowded belt can also stop falling materials and make the residue problem appear worse.

Q: How should I separate gold from seed?

Place a filter or sorter after the main processing route, configure the gold branch for gold, and send seed to a separate storage or planter area.

Q: What is the best way to troubleshoot a stalled compressor setup?

Check input material, blocked tiles, belt direction, burner temperature, filter settings, and collector capacity in that order. This identifies most layout problems without unnecessary rebuilding.
