Stone Quarry Cutting Machine
BCTC B2QYKZ - Permanent Magnet Double Blade Quarry Cutting Machine, suitable for granite, marble, and quartz open pit mines.
BCTC B2QYKZ Stone Quarry Cutting Machine
What quarries actually sell are finished stone blocks, not rocks. For every cubic meter of crushed stone unloaded from the quarry, you've already factored in the costs of drilling, stripping, and transportation. The same applies to track mounted stone cutters; the geometry of the stone is determined while it's still upright. The BCTC B2QYKZ is a permanent magnet dual blade Stone Quarry Cutting Machine suitable for open pit granite, marble, and quartz quarrying, equipped with 3600–4800 mm diamond blades, capable of cutting sides and bottom along the same track.
Cross sectional accuracy depends on the controllability of the cutting trajectory
1️⃣ Equipment Working Principle
The B2QYKZ Track Mounted Stone Quarry Cutting Machine is mounted on a pre laid guide rail. The double blades feed linearly along the rail. The depth, width, and direction of the cut are all set on the 7 inch control panel.
2️⃣ Permanent Magnet Synchronous Motor
The machine senses the hardness of the stone by monitoring the current and automatically adjusts the speed. It slows down when encountering hard stone and speeds up when encountering soft stone, preventing blade jamming.
3️⃣ Cutting Process
The equipment mainly performs longitudinal vertical cutting, cutting the raw stone into strips along the rail with a smooth cut surface. Bottom cutting is completed in conjunction with a diamond wire saw or horizontal drilling equipment.
4️⃣ Advantages Compared to Traditional Mining
Traditional blasting/wedge mining: Relies on rock joints for judgment, the cross section is uncontrollable, the finished product is prone to irregularity, and the stone is often downgraded and its value reduced.
Track cutting solution: The direction and depth of the vertical cut can be set manually, resulting in precise and square shaping of raw blocks, priced per whole block.
Dual blade synchronous cutting, unified benchmark control of block size
✅ Dual blade shared spindle structure: Two blades share a single spindle. The blade spacing is pre set according to the width of the block. A single feed produces two long side strips, increasing production efficiency by over 10%. The equipment travels linearly along pre laid guide rails, using the rails as a unified benchmark to ensure vertical cutting accuracy and eliminate dimensional deviations caused by multiple clamping operations.
✅ Higher output efficiency: Compared to single blade face by face cutting, the top side composite cutting process increases cutting efficiency by over 40%, significantly reducing the problem of missing corners in the block and avoiding delivery losses due to non compliant dimensions.
✅ Rock type adaptive stepless speed regulation: The spindle supports stepless speed adjustment. The frequency converter identifies the stone hardness through current monitoring and can flexibly adjust within a given speed range, saving 10%~20% more energy than ordinary asynchronous motors. It is suitable for various stones such as granite, marble, and quartz.
Designed specifically for outdoor working environments
🔆Strengthened structure and simple layout
High overall rigidity and durability. All components are easily accessible for operator maintenance. Four axis direct drive replaces traditional V belts, avoiding problems caused by belt tension variations.
✨Wide voltage input
Supports rated voltage range of AC three phase 440V and below. Electrical components are configured for harsh working conditions such as mine dust and unstable voltage. Key components use brands such as Siemens.
🌟Road supported workload:
The series' total weight is 7000–12000kg (depending on the model). The track can be extended as the working face advances, enabling layer by layer mining.

A 3600mm diameter saw blade has a cutting edge circumference of approximately 11.3 meters. At a spindle speed of 200 rpm, the linear velocity can reach 37.68 m/s, which falls within the applicable range for granite diamond saw blades. This type of low speed, high torque, heavy duty cutting condition is precisely where permanent magnet synchronous motors excel. The BCTC B2QYKZ series, from Ningde, a leading brand in China, offers a speed range of 200–1400 rpm, automatically adjusting the cutting feed speed to protect the saw blade and achieving 10%–20% energy savings compared to ordinary asynchronous motors.
