A quarry is the place where natural minerals, stones, sands, gravels, industrial minerals... neither metallic, nore carboniferous are processed. If most of the quarries are opened sky, some deposits can be operated underground.
There are mainly 3 kinds of quarries :
Loose rocks quarries : extraction of alluvial aggregates such as sand, gravels, pebbles...
Massive rocks' quarries : limestone and extraction and eruptive aggregates.
Dressed stones quarries : stone blocks intended to shaping in plants or to manufacture products for funerary art, building industry, highways or decoration.
The industries of this field operate taking into account the environmental standards.
Wiithin the ressources optimization and complying with the standards, Neyrtec Mineral bring expertise, offering operating solutions and necessary equipments for upgrading aggregates or effluent processing for the supply of equipments or turnkey solutions.
The equipments used in the quarries are :
- ROLOFLUX washing and elutriation drums
- Sand processing SANDYFLUX waters or muds processing CLARIFLUX - THICKENERS - PASTE THICKENERS - FLOCCULATION STATION
- Minerals particles cleaning and polishing with the ATTRITION CELLS
- Dewatering of the minerals for storage with the DEWATERING SCREENS
Aggregates or sands classification by size fraction.
Sands' washing by removing the fines interfering with their use in concrete.
Aggregates separation by size fraction enabling an upgrading of the product.
Muds thickening in order to reduce the storage areas or the volumes to carry away.
Improvement of the equipments' operating range with maintenance optimization.
