Grinding Ores and Materials with Crushing Wheels, Millstones, and the Crusher
Create offers several mechanical ways to break down ores and materials into more useful forms. Crushing Wheels, 
Millstones, and the Crushing and Milling processes each handle different inputs and return different outputs.
Grinding with Crushing Wheels
A pair of Crushing Wheels grinds items very effectively. Their Rotational Input has to make them spin into each other. Items thrown or inserted into the top will get processed, and items can be inserted and picked up through automated means as well.
Grinding with Millstones
Millstones process items by grinding them. They can be powered from the side using cogwheels. Throw or Insert items at the top. After some time, the result can be obtained via Right-click, and the outputs can also be pulled out by automation.
The Crushing Process
Crushing has 211 recipes. It handles ores, raw materials, storage blocks, and other items.
Block of Amethyst -> 
Amethyst Shard x3
Amethyst Cluster -> Amethyst Shard x7
Blaze Rod -> 
Blaze Powder x3
Netherrack -> 
Cinder Flour
Coal Ore -> 
Coal
Deepslate Coal Ore -> Coal x2
Copper Ore -> 
Crushed Raw Copper x5
Deepslate Copper Ore -> Crushed Raw Copper x7
Veridium -> Crushed Raw Copper
Cut Veridium -> Crushed Raw Copper
Gold Ore -> 
Crushed Raw Gold
Deepslate Gold Ore -> Crushed Raw Gold x2
Ochrum -> Crushed Raw Gold
Crushing also works on tagged inputs, which lets it accept whole categories of materials at once:
- #c:ores/aluminum ->
Crushed Raw Aluminum - #c:raw_materials/aluminum -> Crushed Raw Aluminum
- #c:storage_blocks/raw_aluminum -> Crushed Raw Aluminum x9
- #c:raw_materials/copper -> Crushed Raw Copper
- #c:storage_blocks/raw_copper -> Crushed Raw Copper x9
The Milling Process
Milling has 246 recipes. It is the route for turning plants, minerals, and organic items into dyes and other products.
Charcoal -> 
Black Dye- Coal -> Black Dye x2
Ink Sac -> Black Dye x2
Wither Rose -> Black Dye x2- #botania:petals/black -> Black Dye
Cornflower -> 
Blue Dye x2
Lapis Lazuli -> Blue Dye x2- #botania:petals/blue -> Blue Dye
Bone -> 
Bone Meal x3
Calcite -> Bone Meal
Cocoa Beans -> 
Brown Dye x2- #botania:petals/brown -> Brown Dye
Choosing Between Them
Both Crushing Wheels and Millstones accept items at the top, and both can be fed and emptied by automated means. The difference lies in their recipes: Crushing covers ores, raw materials, and storage blocks, while Milling covers dyes and similar outputs. Match the machine to the recipe you need, and remember that tagged inputs let a single setup handle many material variants without changes.
