Rotary tumbler is common because in this you can do all the four processes, Shaping, Fine Grit, Pre-Polish and Polish.

Rock Tumbling Process
All the tumblers have barrels either they are made up of plastic or any metal. Those barrels are loaded with rocks, water, and abrasive grit. The abrasive grit is basically a granular material, they are like grains glued onto sandpaper. The grit is often marked as coarse, medium, and fine, varies from different grades of sandpaper.
To start tumbling the barrel containing rocks, grit, and water is placed on its motorized machine that rotates the barrel containing rocks that are inside. As the rocks start tumbling, they chore against one another with particles of the abrasive grit caught between them. This stage wears sharp edges off of the rocks and soften their surfaces. The tumbler that works this way are mostly rotary tumbler.
The rocks are usually tumbled for one or two weeks in coarse grit, almost one week in medium grit, and a week in fine grit, with an intense cleaning of the rocks and the barrel. Then those rocks are tumbled for almost one final week with water and a rock polish. And there comes your brightly polished stones.
Some of the rocks are so hard that they need extra time or extra process to go through, so that their brightness will be enlightened. For that you just need to fill your barrel with these soap or any powdered laundry detergent and rocks. This process will remove any left out haze from your rocks and will make your rock more shining and will brighten them up.
