Sandustry Mechanics: Pixel Physics, Density, Reactions, and Automation
Understand the systems behind Sandustry: matter states, density, permeability, gravity, heat, cold, reactions, and machine flow.
Most Sandustry problems become easier when you identify four things: matter type, density, containment, and the next intended reaction. Machines then become tools in a physical system rather than isolated recipes.
Core systems
- Pixel-level matter and density
- Gravity and pile behavior
- Liquid containment and corner leaks
- Heat, cold, melting, freezing, and steam
- Permeability of belts, filters, and machines
- Signals, sensors, and logic after physical flow is stable
Diagnostic loop
- 1
Pause or isolate the input.
- 2
Name the material state at the jam.
- 3
Check whether the supporting block contains that state.
- 4
Clear the output and test a small batch.
- 5
Scale only after the module repeats reliably.
Frequently asked questions
Why do Sandustry factories jam?
Common causes are blocked bottom pixels, tall mixed piles, state changes inside Filters, and outputs with no overflow space.
