Pneumatic and Hydraulic DTH Drilling Machine is specially useful for rugged and accidented areas where other DTH drilling rig can not work normally.With compact structure, easy operating, fast drilling, high efficiency, easy to disassemble and very convenience for carrying.
Hydraulic DTH (Down-The-Hole) Drilling Machine is a powerful piece of machinery that is commonly used in various types of mining, construction, and tunneling projects. This powerful drilling machine uses a pneumatic hammer that is attached to the end of a drill pipe, which is then inserted into the ground or rock surface to create holes.
Hydraulic DTH drilling machines are known for their reliability, durability, and efficiency. These machines can drill deep holes in many different types of terrain, including hard rock, sandstone, shale, and other abrasive materials. They can be operated remotely from a control panel or manually by an operator.
⭐ Detailed Description for Pneumatic-Hydraulic DTH Drilling Machine | Stone Quarry Drilling Rig
High-Efficiency Pneumatic-Hydraulic DTH Drilling Machine for Granite & Marble Quarries
The ToolWits Pneumatic-Hydraulic DTH Drilling Machine is a powerful and efficient quarry drilling rig designed for stone block mining, pre-splitting, and deep-hole drilling in granite, marble, limestone, and other hard rock formations. By combining hydraulic rotation and feed force with a pneumatic DTH hammer, this machine ensures superior penetration speed, stable operation, and long-lasting performance in demanding quarry environments.
This advanced drilling system is widely used in stone mining companies, construction sites, road engineering, and blasting operations, meeting the high-precision drilling requirements of modern quarries.
🔧 Key Features & Performance Advantages
1. Hybrid Power System (Hydraulic + Pneumatic)
Hydraulic system provides strong rotation torque and stable feed control.
Pneumatic system powers the DTH hammer to deliver high-frequency impact energy.
Ensures fast drilling speed, low energy loss, and smooth operation even on the hardest stone.
2. Superior Drilling Efficiency
DTH hammer strikes directly behind the drill bit, reducing power loss.
Delivers higher penetration efficiency than traditional top-hammer drilling.
Ideal for deep drilling in hard rock quarries.
3. Multi-Angle Drilling Capability
Supports vertical, horizontal, and inclined drilling.
Perfect for pre-split holes, block cutting lines, anchor holes, and blasting holes.
Flexible structure adapts to rugged quarry surfaces and narrow bench spaces.
4. Strong Air Flushing & Cooling System
Compressed air removes cuttings efficiently from the hole to prevent clogging.
Reduces bit wear and maintains consistent drilling performance.
Enhances service life of drill rods and down-the-hole hammers.
5. Durable Structure & Reliable Components
Made from high-strength steel and industrial-grade hydraulic/pneumatic parts.
Suitable for continuous heavy-duty operation in stone quarries.
Designed with low maintenance requirements, reducing operating costs.
6. Easy Operation & Mobility
Compact body makes it easy to reposition on quarry benches.
User-friendly controls for safe and efficient operation.
Designed for both small and large mining environments.
