Millstone | Create Wiki | Fandom
The Millstone is a more basic equivalent of the Crushing Wheels, capable of applying milling recipes to any items inserted from above. A Millstone can be powered by a Shaft from below or by a Cogwheel from the side. There are two ways to insert items into a Millstone: Dropping items on top of it: anything that can be processed will be picked up if the input buffer is empty. .
