The Diamond Pacific Mini-Sonic Hopper - 4 lb. Capacity tumble polishes almost any stone or metal piece with ease. Delicate jewelry, coins, and precious gems will come out gleaming thanks to this tumbler's gentle yet dependable operation. Unlike most tumblers, the Mini-Sonic doesn't operate with a motor; in fact, there are no moving parts at all, meaning the machine lasts longer. It's also gentler on your stones, letting them keep their original shape even after polishing.
Tumbling is controlled by an interrupted electrical current, which creates a vibration that drives the rotation of the hopper. Control the rotation and intensity with solid state electronic controls. While the tumbler is running, the load is separated, compacted, and then separated again during each cycle. This improves the process and helps draw fresh abrasive up into your materials each time. The hopper stays almost motionless; it's the materials inside that move. Only a small amount of abrasive is required; as it begins to break down, it forms a slurry that coats your materials.
The Mini-Sonic operates with 3600 vibrations per minute on 60Hz of power. Load capacity is approximately 4 pounds. The hopper is made from cast polyvinyl. Lid included.
Only a small amount of water and abrasive is required for operation. Too much of either will cause material to collect in the hopper and prevent proper rotation.
