1. PAINPOINT DRIVEN OPENING

Managing a luxury quarry site in Lagos presents distinct operational and commercial challenges. The demand for highpurity, visually flawless granite, marble, 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, energy consumption, and the need for secondary finishing? These inefficiencies directly erode your profit margin on highvalue stone. The core question becomes: how can you increase block yield, improve cut quality, and reduce total extraction costs to maximize the return from your premium stone reserves?

2. PRODUCT OVERVIEW

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.

Operational Workflow:
1. Drilling & 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 & Alignment: 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, dust suppression, and wire cooling.
4. Block Separation & Handling: Once the cut is complete, the block is separated, often using air bags or hydraulic splitters, and moved for further processing.

Application Scope: Ideal for extracting large blocks of granite, marble, limestone, travertine, and other premium natural stones where yield and surface quality are paramount.

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

3. CORE FEATURES

Adaptive Tension Control | Technical Basis: Hydraulic servosystem with realtime load sensors | Operational Benefit: Maintains optimal wire tension during cutting, preventing whip, reducing breakage risk in variable hardness stone | ROI Impact: Reduces unexpected wire failure downtime by up to 40% and extends wire life.

Dynamic Frequency Drive (DFD) | Technical Basis: Solidstate power conversion controlling AC motor speed/torque | Operational Benefit: Allows operators to finetune wire speed and torque to match specific stone hardness and abrasiveness | ROI Impact: Improves cutting rate by 1525% while lowering energy consumption per cubic meter extracted.

Modular Track System | Technical Basis: Precisionmachined alloy rail segments with laseralignment mounts | Operational Benefit: Enables rapid setup for parallel cuts and exact squaring of blocks directly in the quarry bench | ROI Impact: Increases usable block yield by minimizing excess waste rock, improving overall recovery from the reserve.

Automated Water Recycling Unit | Technical Basis: Multistage filtration and settling tank system | Operational Benefit: Recirculates up to 90% of process water, continuously cleaning slurry from the cutting line | ROI Impact: Drastically reduces water procurement costs in Lagos sites by approximately 80% and minimizes environmental discharge.

Centralized PLC Interface | Technical Basis: Industrial programmable logic controller with humanmachine interface (HMI) panel | Operational Benefit: Provides operators with realtime data on power draw, linear speed, tension alerts, and maintenance schedules | ROI Impact: Enables predictive maintenance scheduling based on actual load data rather than hours run.
