Modern Granite Quarrying in Macheng, China: How Quarry Wire Saw Machine and Double-blade Mining Machine Improves Block Extraction
As one of China’s most important granite production regions, Macheng has become a representative example of modern stone quarrying transformation.
With increasing demands for:
- Higher block quality
- Safer quarry operations
- Environmental protection
- Better resource utilization
traditional blasting methods are gradually being replaced by advanced mechanical cutting technologies. Today, one of the most widely adopted quarrying methods in Macheng granite quarries is
Quarry Wire Saw Machine + Double-blade Mining Machine Combination Cutting Method
This solution combines the advantages of large Quarry Wire Saw Machine + Double-blade Mining Machine technology to achieve cleaner, safer, and more efficient block extraction.
As a professional manufacturer of stone quarry equipment and diamond wire solutions, Skystone Group continues to support global quarry operators with reliable quarry cutting systems for modern stone production.
Why Modern Quarries Prefer Mechanical Cutting Instead of Blasting
Traditional blasting can create several problems during granite extraction:
- Internal cracks inside blocks
- Low recovery rate
- Irregular block sizes
- Safety risks
- Heavy vibration and dust pollution
For premium granite materials such as:
- Black granite
- Sesame White granite
- Export-quality dimensional stone
- Block integrity is extremely important.
This is why more quarries in Macheng are now adopting:
Double-blade Mining Machine Vertical Cutting + Quarry Wire Saw Machine Bottom Cutting
to maximize quarry productivity and stone quality.
Quarry Bench Preparation
Before cutting begins, the quarry bench must be properly prepared. The preparation process includes:
- Removing loose stones
- Leveling the working area
- Building access roads
- Preparing drainage systems
- Reserving space for block overturning and loading
A stable quarry platform is essential for accurate cutting and safe machine operation. Modern quarry machines from Skystone Group are designed to operate under continuous heavy-duty quarry conditions while maintaining cutting stability and efficiency.
Vertical Cutting by Double-blade Mining Machine
After the bench is prepared, the Double-blade Mining Machine begins the main vertical cutting work.
Main Functions of Double-blade Mining Machine
- Longitudinal cuts
- Side cuts
- Primary separation cuts
- Surface trimming
Advantages of Double-blade Mining Machine
- Cleaner Cutting Surface: The cutting surface becomes smoother and more regular.
- Higher Block Recovery Rate: Mechanical cutting significantly reduces hidden cracks inside the granite.
- Better Block Dimensions: Block sizes become more standardized for further processing.
- Reduced Material Waste: More usable stone can be recovered from the quarry.
Skystone quarry cutting machines are engineered with reinforced structures and stable rail systems to improve long-term cutting precision in hard stone quarry environments.
Drilling for Diamond Wire Installation
Once the vertical cuts are completed, drilling work begins for the diamond wire saw bottom cutting process. Operators use:
- DTH drilling machines
- Horizontal drilling equipment
to create intersecting holes through the rock mass. After drilling, the diamond wire is threaded through the holes and connected into a continuous loop.
Quarry Wire Saw Machine Bottom Cutting (“Undercutting”)
This is the most critical stage of the entire quarry extraction process.
What Does “Bottom Cutting” Mean?
Separating the granite block horizontally from the mother rock. Because large quarry disk saws usually cannot fully cut the bottom section, the diamond wire saw completes the final separation.
How Diamond Wire Saw Machines Work
The diamond wire rotates at high speed around the rock using:
- Diamond beads
- High-speed friction
- Continuous water cooling
Diamond Wire Saw Cutting Procedure
1. Guide Pulley Installation: Operators install Main flywheel, Guide pulleys, and Tension system to ensure stable wire movement.
2. Machine Startup: Wire speed gradually increases, Hydraulic tension stabilizes the wire, and continuous cutting begins.
Skystone diamond wire saw machines are optimized for stable tension control, high cutting efficiency, and adaptability to different granite hardness levels.
3. Water Cooling and Slurry Removal: Continuous water supply reduces cutting temperature, removes stone slurry, and extends diamond wire lifespan.
Block Overturning
After the bottom cutting is completed, the granite block becomes fully separated from the mountain. Operators use:
- Hydraulic pushers
- Airbags
- Excavators
- Hydraulic jacks
to carefully overturn the block. This operation requires professional coordination to avoid block damage.
Block Squaring and Loading
Once the block is safely overturned, additional processing may include Edge trimming, Squaring, and Secondary cutting to create standard export block dimensions.
Finally, the blocks are transported using:
- Gantry cranes
- Wheel loaders
- Excavators
- Quarry lifting systems
Main Advantages of Quarry Wire Saw Machine + Double-blade Mining Machine Combination
- Higher Block Quality: Mechanical cutting minimizes internal fractures.
- Higher Quarry Yield: More usable granite can be extracted.
- Safer Quarry Operation: Reduced blasting means lower operational risks.
- Environmentally Friendly: Lower vibration, less noise, and reduced dust pollution.
- Better Production Control: Standardized block sizes improve downstream efficiency.
