Used for transferring materials between Hoppers or select machines. No power required. Open conveyors below a certain depth are susceptible to attack from mynocks and will not work reliably within the cold and toxic caverns.
Conveyor transfer rates are dependent on the transfer rate you chose when you started your world. The Fast Conveyor world option will transfer at a maximum rate of 100 items per minute; and 60 items per minute with the Slow Conveyor option.
