H+B drum machine for grinding and polishing stones. Super quality machine and containers, the V-belt is Kevlar reinforced and not the normal O-ring that breaks easily. The machine comes with two rubber containers for 1 kg stones each and a complete grinding powder set with 500 grams of grinding powder in each fineness and 500 grams of polishing powder.<\/p>\n
Grinding is done by \"rumbling\" the stones inside the rotating rubber containers together with water and grinding powder. There can be about 1kg of smaller stones (max. walnut size) in each container. Grind with 4 different finenesses of abrasive powder and finally polish, also in the container. The whole process takes about 4 weeks and costs less than 100 kr. in grinding powder and electricity.<\/p>\n
Abrasive powder, silicon carbide, in grit sizes 80 - 220 - 400 - 800 is used. Aluminium oxide is used as polishing powder. In order to maximise the shine of the stones in the long run, you should use one container exclusively for polishing. If necessary, buy an extra one for this purpose.<\/p>\n
The polished stones can be used to make jewellery, figures, mosaics... The only limit is your imagination. With a small diamond saw (no teeth, not dangerous) you can cut and shape stones. Gives you many more possibilities.<\/p>","protected":false},"excerpt":{"rendered":"
