Then, cone crushers make the pieces even tinier, getting the ore ready for the next steps. Next up is grinding, which is done in special mills like grinding mills, ball mills, or rod mills, depending on what we need. The goal is to get the ore just the right size so we can get as much valuable stuff out of it as possible.
