This mod adds three windmills:

• Windmill - Makes concrete and flour
• Sawmill - Makes planks
• Masonry Mill - Makes bricks and slabs

Mitty and I did some testing. We tried various containers and configurations. Crate racks won't work. BSB's won't work. Other containers won't work.

1. Expand a BCU so it has a main container.
2. Expand at least two rafts. Put them in the BCU main container. You'll want 61+ cast.
3. Put the BCU in the windmill.
4. To mass craft concrete add stone shard to one raft and clay to the other, 100 each. Creates 100 concrete at a time.

You can also just combine clay and slab into larger parts and put them in the BCU. However, using combined ingredients causes the crafting process to step through the actions instead of doing them all at once.

I assume the other windmills work the same way.

More as I know it.
