Shaker - Sandustry Wiki

Overview

The Shaker is a production building that processes Wet Sand into Residue, with a chance to extract Gold. It matters because it automates the opening Gold process while physically separating Gold below the machine from Residue left on top.

This page reflects the official Wiki and current Early Access gameplay evidence checked on August 17, 2026. It does not use Demo-only costs, names, or progression claims.

How to Obtain

Current Early Access gameplay shows the tutorial Objectives leading players from manual Gold recovery to building a Shaker. Follow the Objectives in your current build rather than relying on a fixed cost or unlock sequence: the checked sources do not establish a permanent research cost or universal build order.

How It Works

Stage	Verified Behavior
Input	Place Wet Sand on top of the Shaker.
Processing	Each Wet Sand pixel becomes Residue and has a 25% chance to also produce one Gold pixel.
Output	Gold passes through and drops from the bottom; Residue remains on top and moves slowly toward the side.
Behavior	Gold is the only solid that passes through the Shaker. Other solids remain on top unless they are manually dragged into the machine body, where they can become trapped.

Because Gold is probabilistic, a small batch may produce more or less Gold than another batch. The 25% chance is not a fixed throughput promise.

Used For

Opening Gold production: The Shaker automates the Wet Sand processing step used to recover Gold.
Research progression: Gold routed into a Collector becomes available as Research currency.
Factory automation: The machine connects the Wet Sand input stage to separate Gold collection and Residue routing paths.

Collector — receives the Gold output so it can count as Research currency.
Conveyor Belt — can move solids along a horizontal route around the processing line.
Launcher — can lift or throw solids when a route needs elevation or side movement.
Filter — can separate selected solids when a Shaker line contains mixed materials.

Wet Sand — the Shaker’s input material.
Gold — the probabilistic output that passes through the machine.
Residue — the guaranteed output that remains above the machine.

Tips and Notes

Feed a small amount of Wet Sand onto the top first and confirm that Gold exits below.
Keep a clear route for Residue. Current Early Access gameplay repeatedly shows Residue buildup covering the Shaker surface and slowing the line.
If Wet Sand is not being processed, check whether it reaches the top surface and whether Residue or another solid is covering that surface.
Do not treat one working layout as the required design. The verified sources do not establish a best orientation, machine count, or throughput ratio.

FAQ

What goes into a Shaker in Sandustry?

Wet Sand goes on top of the Shaker. The machine converts it into Residue and has a 25% chance per Wet Sand pixel to also extract one Gold pixel.

Why is Residue blocking my Shaker?

Residue remains on top and moves away slowly, while incoming Wet Sand also needs access to that surface. Reduce or pause the input, clear the top and side route, and then resume with enough space for Residue to leave.

Why is Wet Sand not being processed?

Check that the Wet Sand is landing on the top surface rather than beside the machine. Also remove Residue or other solids covering the surface. Current gameplay evidence shows that excessive input and blocked output can create the same visible backlog.

Is Gold guaranteed from every Wet Sand pixel?

No. The official Wiki gives each processed Wet Sand pixel a 25% chance to produce one Gold pixel, while Residue is produced every time.
