Double Blade Granite Quarrying Machine for High-Productivity Block Extraction | STONEX 2QYKZ
When granite quarry operators need to increase production without relying entirely on diamond wire sawing, the STONEX 2QYKZ Double Blade Granite Quarrying Machine provides a highly efficient mechanical cutting solution.
Designed for granite, marble and other dimension stones, the 2QYKZ combines two large diamond circular saw blades, rail-mounted travel and high-efficiency permanent-magnet motor technology to create long, deep and parallel cuts directly in the quarry.
Cut More Stone in Less Time
The biggest advantage of the double-blade design is simple: two blades work simultaneously.
Instead of repeatedly repositioning a single cutting head, the 2QYKZ can create two parallel cuts during the same cutting operation. Depending on stone hardness and working conditions, the cutting depth per pass can be approximately 150–250 mm.
For reference, the 2QYKZ-3600 can travel approximately:
• 150 m/day when cutting granite
• 200 m/day when cutting marble
These figures are based on approximately 20 hours of operation per day and actual productivity will vary with quarry conditions, stone hardness and cutting parameters.
Up to 15 m²/h Cutting Productivity
In suitable quarry conditions, STONEX estimates the double-blade system can achieve approximately 15 m²/hour, compared with around 10 m²/hour for a conventional diamond wire saw.
For quarry operators, higher cutting productivity can translate into:
• More working meters per day
• Higher block production potential
• Better utilization of quarry equipment
• Reduced cutting time per production cycle
• Greater output from the same working area
Lower Cutting Cost
Productivity is only half of the equation. Operating cost matters just as much.
STONEX estimates cutting consumption at approximately USD 1.00/m², compared with around USD 1.50–2.30/m² for wire sawing, depending on operating conditions and consumables.
This makes the double-blade quarrying system particularly attractive for high-volume granite quarry operations where cutting cost per square meter directly affects production economics.
Adjustable Cutting Width for Different Blocks
The two blades can be configured for different cutting widths, with available configurations covering approximately 1,360–3,300 mm, depending on the machine and blade arrangement.
This allows quarry operators to adjust the cutting geometry according to:
• Desired block dimensions
• Quarry bench conditions
• Stone type
• Geological structure
• Production requirements
Large Blades for Deep Quarry Cutting
The 2QYKZ Series is available with large blade diameters from:
3,600 / 4,200 / 4,600 / 4,800 mm
Maximum cutting depth reaches approximately 1,500–2,100 mm, depending on model.
For example, the 2QYKZ-4600 has a published maximum cutting depth of approximately 2,000 mm, while the theoretical blade-depth calculation under the stated configuration can reach about 2,050 mm.
High-Efficiency Permanent-Magnet Drive
The 2QYKZ uses PMSM permanent-magnet motor technology, including an IE5 high-efficiency motor configuration.
Combined with adaptive control, this system is designed to improve cutting efficiency and reduce energy consumption per mined unit.
Built for Demanding Quarry Conditions
Granite quarrying is a harsh operating environment. The 2QYKZ is designed with:
• Reinforced heavy-duty structure
• Wide voltage input of 90–520 V
• Water cooling for diamond blades
• Optimized maintenance access
• Optional remote monitoring
• Optional mobile-phone and computer control
• Optional lightning protection module
A More Productive Alternative to Conventional Wire Sawing
For quarries focused on commercial granite blocks, the STONEX double-blade quarrying machine can work as a complementary technology alongside diamond wire saws.
A practical production strategy can be:
Double-Blade Saw → Long Parallel Cuts → Bottom Cutting/Separation by Diamond Wire Saw → Block Separation by Drilling & Hydraulic Splitting → Block Extraction
This allows each technology to be used where it performs best.

FAQ
Q: How fast can the STONEX double-blade quarrying machine cut granite?
A: The 2QYKZ-3600 can travel approximately 150 m/day when cutting granite under the stated operating conditions. Actual productivity depends on stone hardness, cutting depth and quarry conditions.
Q: How much can the double-blade machine cut per hour?
A: STONEX estimates approximately 15 m²/hour in suitable conditions, compared with around 10 m²/hour for wire sawing.
Q: What cutting width can the double-blade quarry saw achieve?
A: Depending on blade configuration, the cutting width can be approximately 1,360–3,300 mm.
Q: How deep can the machine cut granite?
A: Depending on the model, maximum published cutting depth is approximately 1,500–2,100 mm.
Q: How many machines are recommended for a granite quarry?
A: STONEX generally recommends approximately one double-blade machine for every 3,000 m² of working area, subject to the quarry's production plan and geological conditions.
Q: How much rail is required for one machine?
A: A typical configuration uses approximately 300 meters of rail per machine.
Q: Can the double-blade machine replace a diamond wire saw?
A: It can reduce dependence on wire sawing for suitable straight cuts, but many quarries can achieve the best overall workflow by combining double-blade cutting with wire sawing and other block-separation technologies.
