The stages of limestone transformation
1 - Quarry extraction
Extraction of massive natural stones blocks from our quarry near to Barcelone or from the quarry of Minière close to our production area. Reception of the blocks from 2 to 10 tons at the sawing station.
2 - First production step
• Saws up to 2.7m of diameter which are composed with 140 diamond prongs. Fully automated, saws perform slices at a forward speed of 25 to 30cm/min.
• Silos for recycling water in a closed systems, sludge treatment and filtration.
3 - Secondary production and finishes step (according to requests)
« La cliveuse »
• Hydraulic presses up to 240 tons of compression to realize different size of setts.
• Dividing slices into ingots of widths and lenghts required.
• Maximum heigh of slices : 50cm
• Digital machine control.
« L’éclateuse »
• This machine allows to calibrate the dimension of the finished setts..
• Hydraulic compression power : 80 tons
Machine tool with a rotating head to treat the limestone surface and makes it non-slip.
Flaming machine :
Products passed beneath a flame head. This creates a chemical reaction between the binary gases and the iron oxides in the stone, giving it a rough, non-slip appearance.
Ne fonctionne que sur du calcaire très dur et chargé en oxyde de fer.
Finish obtained by passing the setts through a tunnel. They knock against each other, eroding the sharp edges and giving the sett an older, more rustic look.
This machine allows to realize special requests : quarter round, curved pieces, customised pieces…
