Rock Tumbler Media


Rock tumbling media
Tumbling media has three functions: 1) it delivers grit to hard-to-reach rock surfaces; 2) it is used as a filler when tumbling a partial load; 3) it is used to cushion fragile rock materials during the tumbling process. Plastic pellets are to be used in rotary tumblers (they produce too much "bounce" in a vibratory). Ceramic pellets are used in vibratory tumbling but many people also use them in rotary tumblers. If you are tumbling a load of large rocks they will have very few points of contact. However, if you add ceramic cylinders to fill the voids between the rocks there will be a lot more points of contact where grinding action can occur. The result will be faster grinding and smoothing done on surfaces where rock-to-rock contacts would not occur.

We use these for cushioning!
Ceramic pellets work great as a filler and for delivering grit or polish to difficult-to-reach surfaces. These angle-cut cylinders are approximately 3/16" (5mm) diameter x 3/8" (10mm) long. They can be washed and reused along with your rock. When used in the fine grit and polish stages they will last through many tumbling cycles.
