1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Managing a luxury quarry site in Lagos presents distinct operational and commercial challenges. The demand for highpurity, visually flawless granite, marbre, and limestone blocks requires precision that standard extraction methods often fail to deliver. Are you contending with excessive material waste from uncontrolled fracturing? Is your site productivity hampered by the slow cycle times of conventional wire saws or the inconsistent finish from basic chain saws? Do you face escalating costs from blade wear, consommation d'énergie, and the need for secondary finishing? These inefficiencies directly erode your profit margin on highvalue stone. La question centrale devient: how can you increase block yield, improve cut quality, and reduce total extraction costs to maximize the return from your premium stone reserves?

2. APERÇU DU PRODUIT

The solution is a highprecision diamond wire saw system engineered specifically for luxury quarry sites. This equipment is designed for the primary cutting and squaring of large dimension stone blocks with minimal kerf loss and superior surface finish.

Flux de travail opérationnel:
1. Forage & Threading: Pilot holes are drilled at calculated entry and exit points. The diamondimpregnated wire is then threaded through the drill holes and connected to form a continuous loop.
2. System Tensioning & Alignement: The wire is tensioned on a trackmounted drive unit and guided through a system of pulleys to ensure precise cutting plane alignment.
3. Controlled Cutting: The drive unit powers the wire at optimal speed and tension, using a combination of abrasion and friction to cut through the stone with cool water used for lubrication, suppression de la poussière, and wire cooling.
4. Block Separation & Manutention: Once the cut is complete, the block is separated, often using air bags or hydraulic splitters, and moved for further processing.

Champ d'application: Ideal for extracting large blocks of granite, marbre, calcaire, travertine, and other premium natural stones where yield and surface quality are paramount.

Limites: Initial setup requires skilled drilling alignment. Performance is optimal in stable rock masses; highly fractured or heterogeneous formations may require modified techniques.
