Conveyor Belt Mk.I

Conveyor Belt Mk.I is the first-tier conveyor in Dyson Sphere Program, used to transport items between buildings and through factory layouts. It can connect directly to many production and storage structures, including miners, oil extractors, storage tanks, and logistics stations, and it also works together with sorters to move items into and out of buildings. As the slowest conveyor tier, it is the basic option for early logistics and the foundation for all higher-tier belts.

Like all conveyor belts, Mk.I can be placed in several routing styles by cycling placement with the default R key. You can choose between square turns and diagonal routing, which makes it easier either to fit belts into tight layouts or to route around planetary poles and other awkward terrain. Belts can also be raised and lowered to cross obstacles or reach stacked ports on buildings such as Splitters and Storage Mk.I / Mk.II. The base slope limit is 0.5 rise over run until Super Magnetic Field Generator is researched.

A placed belt can be upgraded or downgraded, and the upgrade tool will replace it automatically. When upgrading belts, holding the modifier key before clicking upgrades the entire belt segment within build range at once. The same bulk action also applies to deletion: holding the modifier key before clicking removes the whole belt segment within range. Belts can also be merged together, but only in the direction that their cargo is flowing together; when a belt joins a straight belt, the straight belt has priority.

Conveyor Belt Mk.I carries 6 items per second, or 360 items per minute. A full belt holds one item per tile and one item between each pair of tiles, so items move at three tiles per second. Because belts can carry multiple items per cycle, building layouts that depend on them need enough sorter throughput to keep up; otherwise the belt will not be fully utilized. Stack size per inventory slot is 300.

A few practical notes make Mk.I easier to use efficiently:

• The belt can be placed in different height levels, and the baseline placement limit is 12 above ground, allowing up to 13 belts stacked before Vertical Construction research increases the limit.
• While placing, altitude can be adjusted with the arrow keys, and pressing 0 with the relevant placement mode enabled resets the current point to ground level.
• Holding the modifier key while placing disables snapping, which makes it easier to route belts over buildings or other belts.
• For direct item interaction, hover over a belt segment until the white box appears, then click to open the port and insert or remove items manually.
• You can also pick items up directly from belts by holding the modifier key and left-clicking the item, which is useful for quick cleanup or hand-carrying materials.

Mk.I belts are made primarily from Iron Ingots and are the simplest conveyor tier to produce. Higher-tier belts use the previous tier as an ingredient, but upgraded belt tiers do not combine into a single belt stack; each tier is crafted separately.
