A rotary barrel tumbler significantly speeds up the natural erosion process of stones by consistently rotating and using abrasive media. The rotary action of the barrel creates a cascading effect, the rocks lift up the sidewall of the barrel and then slide and tumble back down the barrel over the top surface of the other rocks and abrasive media.
Snapshot of the process (detailed instructions are provided in the instruction manual):
Step 1 - Coarse: Initial Grinding & Shaping of Rough Rocks (Tumble 5-10 days*)
Step 2 - Medium: Smoothing the Initial Grind (Tumble 5-10 days*)
Step 3 - Pre-Polish: Prepares Rocks for Final Polish (Tumble 7-10 days*)
Step 4 - Final Polish: Final Polish of Pre-Polished Rock (Tumble 7-10 days*)
* Tumbling time varies by Mohs hardness of the rough rock type, softer rocks require less time.
** Total tumbling time typically varies from 24-40 day and depends on the type and hardness of the rocks.
