If there is no air, I don’t know how you are going to make compost that doesn’t stink and look slimy. It’s the lack of air in my experience that causes stinky compost.
Like I posted before, weeds should be used before they develop seeds. If I have a weed that has seeds, I throw it on the back patio where it gets the hottest of hot sun, then I throw it on the trash pile where we burn stuff.
Wood ashes can provide another great addition to the compost pile to keep down the acidity.
This big ball has air chamber tubes, actual tubes you see, inside, that bring in air from the outside. I don’t yet know exactly how it works but it does bring in air through these tubes. It looks like the tubes actually go into the stuff in there.
