WHITE SEVILLA QUARRY
BLACK EXTREMADURA QUARRY
GREY ROBLEDO QUARRIES
Quarries and factories are mostly located in the region of Extremadura, in southwest of Spain.
We have large and numerous extraction áreas.
The factories are located in the extraction areas. This reduces transits blocks from quarry to processing, reducing CO2 emissions. Similarly, reduces total project development times.
It has all the necessary machinery to make any type of product and finished.
The elaboration consists of three steps:
- Block transformation
- Final product
Extraction starts with clearing the over burden and developing the operating phases by creating a system of terraces.
The granite blocks are obtained from the faces by blasting, thermal lances and diamond wire cutting machines. Blocks are then separated by controlled explosions. The detonation is controlled to avoid damaging the material.
The stone is then cut to workable sized blocks by wedges and hydraulic or pneumatic drills, ready for storage, sale or processing.
The blocks are transformed into slabs of different thicknesses using 3500 mm diameter water cooled diamond blades. The blocks are cut into slabs by successive cuts. The water aids the cutting, cooling and diluting the suspended particles in solution.
The slabs are then subjected to a finishing process that will depend on the destination, the location and the desired look (sawn, flamed, bush hammered, rustic, polished or honed).
Once the product is finished it is stored on pallets to be despatched to the destination requested by our customers.
