A correctly balanced compost bin should not smell. If yours does, that means your balance of greens and browns is not right.
“Greens” are nitrogen-rich materials, such as fresh grass clippings, fruit and vegetable peelings, egg shells, pet hair, etc. “Browns” are carbon-rich materials, such as peat moss, dried leaves, shredded paper, coffee grounds, dryer lint, etc.
You should aim for a 2:1 ratio of browns to greens. If you get too many greens in your compost, it will begin to smell.
Remember, the recipe for a compost that doesn’t stink is adding two browns for every green!
