Dyson Sphere Program Belts overview If you've played more than a couple of minutes of Dyson Sphere Program, you'll likely have come across Conveyor Belts. These belts are an essential logistic cog in your ever-expanding factory, and required for you to move from manual construction to automation. The function of the belt is extremely simple: it transports items from one place to another. Most buildings which mine or harvest raw materials, such as Mining Machines, Oil Extractors, and Water Pumps, can be directly connected to a belt, so that whatever the building produces will automatically be placed on its attached belt. But for other buildings that produce intermediate and complex component items - such as Smelters, Assembling Machines, and so on - you'll need to attach them to belts using Sorters, because they can't connect directly to a belt.
