Machines
From the humble Grabber to the Rocket Launcher — discover every Sandustry machine and building, what it does, and when to build it.
Introduction
Machines and buildings are the tools you place to mine, move, process and destroy the world around you. Early machines like the Grabber and Hydro Sponge get your first factory running, mid-game logistics machines like pumps, lifts and drones automate transport, and late tools like the Flamethrower and Rocket Launcher dramatically speed up mining and terrain shaping. Knowing what each machine does — and when to build it — saves hours of wasted effort. The machines category documents the full roster, from the humble starter Grabber to the world-shaping Rocket Launcher, with each machine's function, unlock timing and best use case.
Machine Tier Overview
| Machine | Tier | Function |
|---|---|---|
| Grabber | C | Early mining and item pickup |
| Hydro Sponge | B | Absorbs and moves water |
| Smelter | B | Processes ore and slag |
| Flamethrower | S | Fast mining, melts ice |
| Rocket Launcher | S | Rapid terrain destruction |
Machine Roster
Grabber
The first machine you will rely on. The Grabber picks up items and terrain automatically, letting you gather sand and ore without manual collection. It is basic but essential — almost every starter factory begins with a Grabber feeding a sifter or conveyor. It has also received several balance updates during the demo, so check the patch notes for its current behavior.
Hydro Sponge
A Grabber upgrade and upgrade part that absorbs and relocates water. The Hydro Sponge is your main tool for managing fluid terrain — soaking up pools, clearing flooded areas and repositioning water where your production lines need it. It is especially valuable for draining sandy pockets that would otherwise absorb your water reservoir.
Smelter
The Smelter processes raw ore and slag into usable materials, unlocking the production chains that turn mined rock into factory inputs. It is the bridge between mining and manufacturing, and its placement defines how your processing lines flow. Feed it from both ore belts and a slag byproduct line to maximize its output.
Flamethrower
A late-game utility tool that accelerates mining and melts ice on contact. The Flamethrower is the fastest way to reshape frozen terrain, open ice-field routes and reach water sources. It is a tool, not a weapon — Sandustry has no combat — and pairing it with pumps lets you capture the water it melts before it evaporates.
Rocket Launcher
The ultimate terrain-destruction tool. The Rocket Launcher removes large volumes of material in seconds, making it ideal for digging deep shafts, clearing caverns and reaching underground vaults fast. It is resource-hungry, so use it for big jobs rather than daily mining, and reserve it for vertical work where its speed truly pays off.
Core Mechanics
Sandustry's machines fall into four roles: collection, processing, logistics and destruction. Collection machines like the Grabber feed your lines, processing machines like the Smelter and sifting stations transform materials, logistics machines like pumps, lifts and drones move them, and destruction tools like the Flamethrower and Rocket Launcher shape terrain. Early game uses collection and basic logistics; late game leans on processing and destruction to exploit the underground. Because these roles are so clearly separated, you can always tell what a machine is for at a glance, and you can plan a factory layout around which roles you currently need rather than memorizing an undifferentiated list of buildings.
Advantages
The machine roster is well balanced across the progression curve. Every machine has a clear job and a natural unlock timing, so there are no dead-end builds. The tier spread — from the humble Grabber to the Rocket Launcher — gives a satisfying sense of power growth, and the fact that Sandustry has no combat means machines are purely about building and efficiency, which keeps the design focused. This makes the machines category unusually clean: each machine earns its place in the wiki with a distinct function, so readers can quickly find the exact building they need and learn when to build it.
Challenges
Machines can be expensive and require planning. Early on you may not afford the machines you want, and placing them badly means rebuilding whole lines. The Flamethrower and Rocket Launcher consume resources, so they are not free to use. Underground expansion demands vertical logistics, which means lift planning and shaft digging before you can exploit the deep biomes efficiently. Because the game is pre-release, some machine costs and upgrade paths may change during Early Access, so players should verify current numbers against the latest patch notes before committing resources to an expensive building plan. In short, a little research before building saves real time and resources.

Quick Tips
Place machines with future expansion in mind — leave room beside belts for filters and splitters, because retrofitting a cramped line is far more work than planning ahead. A single empty tile beside each machine gives you the flexibility to extend the line later. Good spacing is the cheapest insurance against a costly mid-game rebuild.
The Hydro Sponge is your best tool for managing water; use it to drain areas before building, since sand absorption will otherwise shrink any pool left near sandy terrain. Drain first, build second, and your water storage will stay reliable. Consistent water supply is the foundation of most late-game production chains.
Use the Flamethrower to melt ice and the Rocket Launcher for deep shafts; each tool has a specialty, and using the wrong one wastes the resources it consumes. Match the tool to the job and your mining economy stays efficient. Efficient tool use keeps your resource economy healthy through the whole playthrough.
