Rock Polishing With Tumblers # 2
Rolling tumblers are the most commonly used ranging in size from 4lb. to 40lb. for hobby use and 200 to 300lbs for commercial use The polishing is usually done in four stages (coarse grind, fine grind, pre-polish and polish) with each stage running for 7 to 10 days depending on type and hardness of material. Material and tumbler have to be thoroughly cleaned between each stage.
Vibratory tumblers are much faster requiring approx. two days for each stage but the material and tumbler have to be cleaned and re-started several times for the coarse and fine grind stages requiring more labor time. There are a number of grits and polishes available,
determined by type and hardness of material to be polished. -
ROCK POLISHING WITH TUMBLERS # 1
Like many rockhounds my hobby started by hicking and picking up rocks that were pretty or unusual looking. After accumulating a large amount of rocks I thought what am I going to do with them. I talked with some friends that were rockhounds and they said why don't you get a tumbler and polish them.
That was the beginning of many years of enjoyment from this great hobby.Tumble polishing is only one of many ways to polish rocks but is probably the easy-est and fastest ways to get started.There are two basic types of rock tumblers. Rolling tumblers and vibratory tumblers. I will go into the difference and advantage and disadvantage of them on my next post so check back.
