First orbicular granite quarry opened in Finland

The worldwide first quarry of an orbicular granite with spheres diametres ranging from 15 to 18 cm was recently opened in Finland by a netural stone company.

Quarry Equipment — General considerations

The main quarrying methods are drilling and diamond wire cutting. In many cases also chain cutting is used but only for marble or travertine.

Gang Saw versus Diamond Wire Saw

The gang-saw is more suitable for mass production of thin slabs. In fact, normally there have to be used two (or four, or eight) machines in order to guarantee a continuous material output to the polishing line.

The background stone is Rojo Coralito from Spain.
