Products Description
Rail-Mounted Granite Block Cutting Machine for Efficient Quarrying | STONEX 2QYKZ
Producing high-quality granite blocks requires more than simply breaking rock from a quarry bench. The cutting process must be controlled so that the quarry can efficiently define, separate and extract commercially valuable blocks.
The STONEX 2QYKZ Rail-Mounted Granite Block Cutting Machine is designed for this purpose, combining two large diamond blades, rail-guided travel and high-efficiency permanent-magnet drive technology.
Rail-Mounted Cutting for Long Quarry Benches
The 2QYKZ travels along a heavy-duty rail system, allowing the machine to make long, straight cuts across the quarry bench.
The rail-guided design provides:
• Stable machine movement
• Straight cutting
• Consistent positioning
• Repeatable cutting paths
• Efficient long-distance operation
A typical configuration uses approximately 300 meters of rail for one machine.
Two Blades for Efficient Block Formation
The machine's two large diamond blades cut simultaneously, producing parallel cuts that define the sides of the future granite block.
Depending on the machine model and blade configuration, the cutting width can reach approximately 1,360–3,300 mm.
This makes the 2QYKZ suitable for different block sizes and quarry layouts.
From Parallel Cuts to Granite Block
The 2QYKZ is part of a coordinated quarrying system.
The practical workflow is:
1. Double-Blade Saw
Long parallel cuts into the granite bench.
2. Diamond Wire Saw
Bottom cutting/separation beneath the block.
3. Drilling & Hydraulic Splitting
Controlled block separation and release.
4. Block Extraction
Heavy-duty equipment removes the separated granite block.
This division of work allows the double-blade machine to focus on what it does best: fast, long and parallel quarry cuts.
Flexible Production for Different Quarry Sizes
STONEX suggests approximately one double-blade machine per 3,000 m² of working area as a general equipment-planning reference.
For intensive production, one machine can potentially produce approximately 4,500–5,000 gross m³ per month, based on the stated operating conditions of around 15–20 days of day-and-night production.
Actual output depends on:
• Quarry geology
• Granite hardness
• Block dimensions
• Cutting depth
• Machine utilization
• Working schedule
• Block recovery rate
For this reason, STONEX can help customers select the appropriate number of machines according to their actual quarry conditions.
Staged Blade Configuration
The quarrying system can use different blade sizes during the cutting process.
According to the recommended configuration, one blade set contains four blades, including:
• Two smaller blades of approximately 2,200–2,400 mm for initial cutting and track formation
• Two larger blades for deeper cutting
STONEX recommends approximately two sets for one machine or three sets for two machines to support production and blade management.
Lower Cutting Cost
For quarry operators comparing double-blade cutting with wire sawing, operating economics are an important consideration.
STONEX estimates:
Double-blade cutting: approximately USD 1.00/m²
Wire sawing: approximately USD 1.50–2.30/m²
Actual costs vary according to stone type, blade/wire consumption, cutting depth, labor, energy and quarry conditions.
Smart and Remote Quarry Management
Quarry equipment may operate in remote locations, making machine monitoring and technical support important.
The 2QYKZ offers optional:
• IoT mobile-phone control
• Remote computer control
• Machine monitoring
• Lightning protection
These options can help quarry owners supervise equipment without always being physically beside the machine.

FAQ
Q: What is a rail-mounted granite block cutting machine?
A: It is a quarry cutting machine that travels along rails while large diamond blades cut the granite bench. The rail system provides controlled and repeatable cutting over long distances.
Q: What is the main function of the 2QYKZ?
A: Its primary function is to make long, parallel cuts in granite and other dimension stones as part of the block extraction process.
Q: Does the double-blade machine complete the entire block extraction process?
A: No. The practical process combines the double-blade saw with a diamond wire saw for bottom cutting/separation, followed by drilling and hydraulic splitting for controlled block separation.
Q: How much rail is needed for one machine?
A: A typical configuration uses approximately 300 meters of rail per machine.
Q: How much area can one machine serve?
A: STONEX generally recommends approximately one machine per 3,000 m² of working area, subject to the quarry's layout and production requirements.
Q: How much can one machine produce per month?
A: Under intensive operating conditions, STONEX estimates approximately 4,500–5,000 gross m³ per month. Actual production varies according to quarry conditions and production organization.
Q: How long can the diamond blade work before segment replacement?
A: For granite cutting at approximately 1,500 mm depth, STONEX estimates approximately 400 meters of machine travel before diamond-segment replacement may be required. Actual blade life varies with granite characteristics and operating conditions.
