Mining Wire Saw Machine

1. Product Overview & Procurement Positioning

The Mining Wire Saw Machine (WSM Series) engineered by Fujian Province Kaida Stone Machinery Co., Ltd. is a heavy-duty, high-efficiency stone quarrying solution designed for open-pit granite, marble, quartzite, and sandstone extraction. Built specifically to handle demanding quarry environments characterized by extreme ambient dust, high humidity, and severe grid voltage fluctuations, the WSM series replaces traditional blasting and manual primary cutting with a high-precision diamond wire cutting process.

By integrating dual frequency conversion drives with PLC closed-loop tensioning, the machine ensures continuous, optimal cutting speeds without wire slippage or excessive wear. For quarry operators facing power supply constraints, optional permanent magnet motor configurations significantly reduce overall electrical draw, allowing mine expansion without requiring costly power grid upgrades.

2. Technical Specifications

Below is the complete engineering specification matrix for the four standard models in the WSM Mining Wire Saw Machine lineup:

3. Working Principle & Drive Technology

Closed-Loop Constant Tension Control

The WSM wire saw machine utilizes a dual frequency converter system coupled with an industrial-grade PLC control module. The system operates on a constant tension feedback loop: as the diamond wire encounters variable rock hardness or structural density changes within the stone mass, the control system dynamically measures cutting resistance and automatically adjusts the machine's backward linear travel speed. This real-time adaptive feed prevents diamond wire snapping, minimizes premature bead wear, and maintains linear flywheel cutting speeds at optimum levels (variable from 0 to 40 m/s).

Permanent Magnet & Wide-Voltage Adaptation

Quarry sites frequently suffer from voltage instability due to long cable runs and heavy machinery startup loads. The WSM drive system is built to operate reliably across wide voltage variance. Furthermore, Kaida offers an optional high-efficiency permanent magnet motor, delivering superior power factor and energy savings that allow high-torque quarrying without overtaxing local substation capacities.

4. Machine Configuration & Structural Architecture

1. Motorized ±180° Rotating Cutting Head: The main flywheel head features electric motor-driven lateral movement and a full ±180° motorized rotation. This allows operators to easily align the wire saw for vertical bench cuts, horizontal bottom cuts, and inclined slope cuts without physically re-positioning the heavy chassis.
2. Phase-Agnostic Electrical Interface: The control system incorporates an automatic phase detection architecture with no phase-sequence restrictions. Operators can connect mine power cables without checking or swapping phase order, protecting internal electronics from phase-inversion damage.
3. Sealed Photo-Electric Proximity Switches: Position control and boundary limits on the cutting head rely on photo-electric proximity sensors engineered specifically to withstand heavy vibration, water spray, and abrasive stone dust.
4. Modular Heavy-Duty Guide Rails: The machine rides on a modular track system of 2-meter steel sections - three sections (6 m total) for the WSM-45, and five sections (10 m total) for the WSM-55, WSM-75 and WSM-90 - with per-section track weights ranging from 80 kg (WSM-45) to 88 kg (WSM-90), allowing rapid disassembly, leveling, and relocation across uneven quarry benches.

5. Safety Protection Systems

To safeguard equipment and quarry personnel during continuous high-load cutting, the WSM series is equipped with a multi-layered safety protection suite:

• Diamond Wire Breaking Protection: Instantly halts machine travel and flywheel rotation if wire tension drops abruptly, preventing loose wire whipping.
• Phase-Loss & Overload Protection: Automatically cuts power if any phase loses voltage or if motor current exceeds pre-set safety thresholds.
• Terminal Limit Position Protection: Photo-electric proximity switches define hard limits for lateral head rotation and track travel, preventing mechanical binding.
• Emergency Circuit Termination: Dedicated control box interlocks allow immediate manual override.

6. Control Interface & Unattended Automation

Touch-Screen HMI Control Platform

The centralized control platform features an intuitive, multi-language touch screen interface that displays real-time operational parameters:

• Main motor current and net cutting current
• Linear wire speed (0–40 m/s)
• Machine traveling speed and direction
• Total accumulated running time and job timers
• System fault diagnostics and protection logs

Unattended Automatic Cutting

The control software seamlessly toggles between Manual Mode (for initial wire setup, notch positioning, and tensioning) and Automatic Mode (for production cutting). Once automatic cutting is initiated, the PLC maintains optimal tension and travel speed autonomously. The machine can run completely unattended, allowing a single quarry technician to oversee multiple WSM wire saw units simultaneously across different quarry faces.

7. Model Selection & Procurement Guide

Choosing the optimal WSM model depends on quarry geology, required cutting face dimensions, and site electrical infrastructure. For secondary processing yards, you can also look into our bridge stone cutting machines:

• WSM-45 (45 kW / 48 kW Total): Ideal for small-to-medium marble and limestone quarries, secondary block trimming, or sites with limited transformer capacity. Maximum cutting distance: 1,850 mm. Total weight: 1,645 kg.
• WSM-55 (55 kW / 58 kW Total): Recommended for medium-hardness granite quarries, standard bench extraction, and general block slicing where balanced power and mobility are required. Maximum cutting distance: 1,950 mm. Total weight: 2,820 kg.
• WSM-75 (75 kW / 79 kW Total): Built for large-scale granite quarrying, hard stone formations (e.g., quartzite, dense basalt), and deep vertical cuts up to 2,100 mm distance. Total weight: 4,050 kg.
• WSM-90 (90 kW / 95 kW Total): Heavy-duty flagship model designed for high-production open-pit granite mines, maximum square-meter hourly output, and extreme-hardness rock conditions. Maximum cutting distance: 2,250 mm. Total weight: 4,500 kg.

8. Installation, Operation & Maintenance Guidelines

1. Track Setup: Lay out the modular guide rail on a leveled quarry bench - 3 sections (6 m total) for the WSM-45, or 5 sections (10 m total) for the WSM-55, WSM-75 and WSM-90. Secure rail anchoring pins to resist backward tractive forces during automatic travel.
2. Wire Threading & Tensioning: Pass the diamond wire loop through pre-drilled vertical and horizontal borehole intersections. Adjust the motorized cutting head position (±180° rotation) until the wire aligns squarely with the flywheel groove.
3. Parameter Calibration: Set target linear speed (typically 22–30 m/s for granite, 30–40 m/s for soft marble) and maximum motor current limits on the touch screen.
4. Routine Maintenance:
   • Inspect rubber flywheel liners daily for groove wear or embedded stone chips.
   • Clean photo-electric proximity switches and check cable connectors for moisture seal integrity.
   • Lubricate lateral head guide ways and rotating gear assemblies per factory intervals.
