    Hannah - The archives here have a lot of information on your
    question. Try searching tumblers. 

    My short answer is this: 

    Vibratory and rotary tumblers perform different actions. Rotary
    tumblers work very well for burnishing metal. Vibratory tumblers work
    very well for abrasive processes. If you want to smooth metal, use a
    vibratory. If you want to burnish metal or work harden it, use steel
    in a rotary tumbler. 

    Superficially, they are both tumblers. The way they work is quite
    different. Further the kind of jewelry that you wish to finish will
    determine how to use mass finishing. 

    I wrote a small book on the subject. It might be useful to buy or
    borrow a copy and get a decent overview of the processes and
    equipment. It is called "Tumble Finishing for Handmade Jewelry",
    subtitled - Small scale mass finishing. All of the Orchid sponsors
    carry the book -- Rio, Gesswein, Otto Frei, and others. Amazon wants
    silly money to carry self published books. They don't have it.
