Why Conveyor Speed Matters
Conveyor speed sets the maximum number of items a single belt can move over time, so it directly determines whether a production line keeps moving or backs up. When machines produce more than a belt can carry, outputs can accumulate and production can stall. Understanding the capacity number makes it easier to build lines that remain workable as more machines feed them.
The most useful rule is simple: compare a belt's items-per-minute capacity with the combined items-per-minute output of the machines using it. The current in-game interface should be your authority for live values, especially after Version 1.0 changes and hotfixes.
| Reported reference | Conveyor belt speed |
|---|---|
| Steam community discussion base value | 60/min |
| Alchemy Factory Codex Early Access setting | 60/min |
| Steam community example with a talent upgrade | 75/min |
The 60/min figure appears in multiple historical sources. However, the Codex source identifies itself as Early Access version 0.5.4471, while the current-version wiki guidance says not to treat community or pre-1.0 figures as current specifications without confirmation in the live game.
Check the Live Belt Capacity
The World tab is the reported place to view speeds and statistics. Several Steam discussion participants state that pressing Tab and selecting World shows the relevant values. A separate belt-speed guide also identifies the World tab as the place to find the exact belt speed number.
This matters because a tooltip may be easy to miss or may not provide every statistic a player needs. Rather than planning from an old guide alone, inspect the current value before committing to a large redesign.
| Task | Reported method | Why it helps |
|---|---|---|
| View general speeds and stats | Press Tab, then select World | Shows world statistics according to community reports |
| Confirm current belt capacity | Check the belt speed value in World | Uses the live-game number |
| Validate an old guide | Compare its value with the current interface | Avoids treating historical data as current |
| Recheck after changes | Inspect the layout and displayed capacity again | Current-version guidance recommends rechecking affected systems after hotfixes |
The current 1.0 reference specifically advises players to use the current build menu, device tooltip, and live production display as the authority for belt behavior. It also notes that official 1.0 materials do not provide a complete table of automation-component rates, costs, capacities, or progression details.
That leaves an important distinction:
- Historical sources can explain the general capacity concept.
- The live interface should determine the number you build around.
- Official patch notes may confirm broad system changes without confirming every conveyor statistic.
- If a displayed value differs from an older community figure, use the displayed value.
Use Items-Per-Minute Math
Both belts and machines can be compared in items per minute. A belt is a hard upper limit: if a line attempts to send more items through it than its capacity allows, the excess cannot move through at that rate.
A cited example uses a machine producing 25 items per minute and a belt moving 75 items per minute. Dividing belt capacity by machine output gives three machines:
| Belt capacity | Machine output | Clean machine count | Combined output |
|---|---|---|---|
| 75/min | 25/min | 3 | 75/min |
| 150/min | 50/min | 3 | 150/min |
These examples illustrate the calculation, not a confirmed list of current machine rates. The useful formula is:
belt capacity per minute ÷ output per machine per minute = supported machine count
When the result is a whole number, the line has a clean ratio. If the total output is higher than belt capacity, the belt becomes the bottleneck. If belt capacity is higher, the belt may appear partly empty but can still carry the line's full output.
For a shared line, add every machine's output before comparing it with the belt:
| Situation | Capacity comparison | Likely result |
|---|---|---|
| Total output equals belt capacity | Output = capacity | Full but balanced belt |
| Total output is below belt capacity | Output < capacity | Empty space on the belt is expected |
| Total output exceeds belt capacity | Output > capacity | Items can back up at machine outputs |
| More machines are added later | Output increases | Existing belt may no longer be sufficient |
The source guidance favors an underfilled belt over a backed-up machine. A belt with spare capacity is not necessarily inefficient; it can provide room for expansion or handle a line whose output does not divide neatly into the belt rate.
Plan Around Bottlenecks
A conveyor's capacity does not make machines produce faster. It only determines how much material can be transported on that belt over time. This is why production upgrades and logistics upgrades need to be considered together.
One community guide recommends keeping belt speed and production speed upgrades aligned to preserve clean ratios. When production increases while belt capacity does not, the line can become awkward to balance. When belt capacity exceeds production, the visual result may be an emptier belt, but the transport limit is less likely to block output.
Use this planning sequence when changing a production area:
- Check the current belt speed in the World tab.
- Identify how many machines feed the same belt.
- Add their output rates together using the live production display.
- Compare that total with the belt's items-per-minute capacity.
- Adjust the line before adding more machines if output already approaches or exceeds capacity.
- Recheck the layout after upgrades or hotfixes that affect the relevant system.
The practical issue is not whether a belt looks full. The issue is whether the line can carry everything machines attempt to output. A full belt can be balanced. An empty belt can be balanced. A backed-up output is the warning sign that transport capacity and production are no longer aligned.
The GamerBlurb guide also warns that a factory can make belts feel slow simply because additional machines are feeding the same line. In that situation, the belt did not necessarily change; demand on the belt increased.
Current-Version Limits and Historical Values
Alchemy Factory launched Version 1.0 on September 8, 2026 at 07:00 UTC, according to the current-version wiki source. That source sets a clear boundary: its official references do not publish complete current tables for recipes, rates, costs, capacities, or progression.
As a result, historical sources are best used carefully.
| Source type | What it can support | What to verify in game |
|---|---|---|
| Steam discussion from December 2025 | Players reported a 60/min base value and a 75/min upgraded example | Current base speed and upgrade effects |
| Early Access Codex version 0.5.4471 | Shows a 60/min conveyor setting | Whether that setting remains current |
| Current 1.0 wiki guidance | Advises checking live interface values | All detailed automation rates |
| Community belt guide | Explains capacity, bottlenecks, and ratio planning | Any specific present-day values |
Do not assume that an old capacity number, upgrade effect, or machine rate still applies after the 1.0 release. The safest workflow is to use historical material for understanding the math, then use the build menu, tooltips, World tab, and production display for the values in your own current save.
This approach also prevents a common planning mistake: designing an entire production line around a number that was accurate in an earlier version but is no longer displayed in the current interface.
FAQ
What is the base alchemy factory conveyor speed?
Historical community and Early Access Codex sources list a base conveyor speed of 60/min. Because current 1.0 documentation does not publish a complete live capacity table, confirm the value in the World tab or other current interface displays.
Where can I see conveyor speed?
Community sources say to press Tab and select the World tab. It is reported to show speeds and other world statistics.
What happens when machines output more than a belt can carry?
The belt becomes the limiting capacity. Items can back up at machine outputs, and production can stall because machines cannot move their output onward.
Is an empty belt a problem?
Not necessarily. An empty belt can simply mean its capacity is greater than the production feeding it. The cited guidance considers this safer than allowing machine outputs to back up.
Should belt speed and production speed be upgraded together?
A community guide recommends keeping them aligned because matching capacity and production helps maintain cleaner ratios. Confirm the current upgrade behavior in the live interface before making a long-term plan.
