Granite Quarry Diamond Wire Saw for High-Recovery Block Extraction
Powerful cutting performance for deep granite quarry cuts, block separation and efficient dimension-stone production.
Granite is one of the most demanding natural stones to quarry. Its high hardness and abrasive characteristics require a cutting system that can maintain stable performance while controlling diamond-wire consumption.
The STONEX Granite Quarry Diamond Wire Saw is engineered for controlled granite cutting and block extraction, offering power configurations from 22 kW to 83 kW and maximum cutting areas of up to 200 m².
For granite quarry operators, the objective is not simply to cut faster. The more important goal is to recover more commercially valuable stone from each quarry section while maintaining efficient production.
Why Diamond Wire Sawing Is Effective for Granite
Granite quarrying often involves large rock masses and deep cuts that are difficult to handle economically with conventional circular saws.
A diamond wire saw can make long and deep cuts through granite while producing a relatively narrow kerf. This makes it useful for:
• Defining block boundaries
• Deep vertical cuts
• Horizontal cuts
• Bottom separation
• Selective block extraction
• Cutting around geological features
The method can also reduce dependence on uncontrolled breaking methods when producing high-value dimension-stone blocks.
STONEX Granite Wire Saw Models
The STONEX range includes:
HSJ-22G - 22 kW main motor
A compact configuration for lower production requirements.
HSJ-55G - 55 kW main motor
A mid-to-high power configuration for more demanding quarry operations.
HSJ-75G - 75 kW main motor
Designed for higher cutting capacity.
HSJ-83G - 83 kW main motor
The largest model in the supplied range, with a maximum cutting area of 200 m² and reference cutting efficiency of 10–20 m²/h.
This allows quarry operators to select equipment based on their granite quarry scale and production requirements.
For granite quarrying, STONEX provides diamond-wire options including W10 and W15 configurations.
The supplied specifications include:
• W10: Ø11.5 mm diamond beads
• W15: Ø12.0 mm diamond beads
• Sintered diamond beads
• Rubber or spring-type coating configurations
• 37–40 beads/m depending on configuration
The correct wire configuration is essential because granite quarries can vary considerably in hardness, abrasiveness, grain structure and geological conditions.
Granite Cutting Performance
According to the supplied technical data, granite-related applications can achieve different cutting rates depending on the stone and wire configuration.
As a practical principle:
Harder and more abrasive stone generally requires more conservative cutting parameters and may result in lower wire life and cutting productivity.
Therefore, quarry operators should evaluate not only the machine's motor power but also:
Wire speed + feed speed + wire specification + granite characteristics + cutting geometry as an integrated system.
Built for Long and Deep Granite Cuts
The larger STONEX models provide:
• Up to 40 m/s main flywheel linear speed
• Up to 1,950 mm maximum cutting distance of the power head
• Up to 200 m² maximum cutting area
• 0–360° power-head rotation
This flexibility makes the machine suitable for different granite quarrying layouts and cutting requirements.
Where Does the Wire Saw Fit in Granite Block Extraction?
For modern granite quarrying, the diamond wire saw does not necessarily need to perform every cutting operation.
A highly practical production strategy can combine different technologies:
Double-blade saw
↓
Long parallel vertical cuts
↓
Diamond wire saw for deep/bottom separation
↓
Drilling + hydraulic splitting where required
↓
Block separation and extraction
This approach uses each technology where it is most effective.
The saw can handle fast, accurate parallel cuts, while the diamond wire saw takes on deep, difficult or bottom separation cuts.
This can be particularly valuable when the quarry is focused on improving block recovery rather than simply maximizing raw-rock removal.
Advantages of a Granite Quarry Diamond Wire Saw
1. Deep Cutting Capability
Suitable for cuts that exceed the practical working range of conventional circular blades.
2. Controlled Block Separation
Provides a more controlled method for separating valuable granite blocks.
3. Flexible Cutting Direction
The rotating power head supports different cutting arrangements.
4. Suitable for High-Value Granite
Particularly useful where minimizing unnecessary damage and waste is important.
5. Multiple Power Options
22, 55, 75 and 83 kW configurations allow equipment selection according to production requirements.
6. Efficient Diamond Wire Utilization
Appropriate wire speed and feed control help balance cutting productivity and wire consumption.
Who Should Consider a Granite Quarry Wire Saw?
A STONEX granite quarry diamond wire saw is particularly suitable for:
• Granite quarry owners
• Dimension-stone producers
• Granite block exporters
• Quarry contractors
• Stone companies expanding mechanized extraction
• Quarries seeking higher block recovery
• Operations requiring deep or horizontal cuts
Build a More Efficient Granite Quarrying System
The best quarrying machine is not necessarily the machine with the highest motor power. The right solution is the one that produces the best combination of recovery, productivity, operating cost and block quality.
STONEX diamond wire saw technology provides granite quarry operators with a controlled cutting solution that can be integrated into a complete mechanized extraction system.

FAQs
Q: What is a granite quarry diamond wire saw?
A: It is a quarrying machine that uses a diamond-impregnated wire to make controlled cuts through granite for block extraction and separation.
Q: Why use a wire saw instead of a large circular saw?
A: A wire saw is particularly useful for deep, long or difficult cuts, including cuts that are beyond the practical depth of a circular blade.
Q: Which STONEX wire saw is suitable for granite?
A: STONEX offers HSJ-22G, HSJ-55G, HSJ-75G and HSJ-83G configurations. The appropriate model depends on cutting area and production requirements.
Q: How long does granite diamond wire last?
A: Wire life depends strongly on granite characteristics, wire specification and operating parameters. The supplied data provides reference values for different stone conditions rather than one universal service life.
Q: Can a wire saw make horizontal cuts in a granite quarry?
A: Yes. With appropriate hole preparation and machine configuration, diamond wire sawing can be used for horizontal and bottom separation cuts.
