1. Professional High Pressure Adaptation for Ultra-Hard Rock
Precisely adapted to 1.05-1.25MPa high-power high-pressure air compressors, it is professionally designed for ultra-hard geology such as granite, dense hard rock and basalt, completely solving the problems of insufficient drilling power and slow progress of medium and low-pressure hammers. It matches the high-pressure equipment configuration of large mines and heavy-duty projects, and can be directly used for heavy-load operation without equipment modification. As a special mainstream tool for hard rock mining, it fills the performance gap of ordinary drills in ultra-hard rock construction.
2. Super Large Piston Heavy Impact & Extreme Rock Breaking Performance
The upgraded oversized heavy-duty piston structure features longer effective impact stroke and greatly increased single impact energy with lossless concentrated force transmission, delivering super penetration for high-hardness rock. With a stable 17Hz ultra-high impact frequency, it ensures rapid and uniform drilling speed, avoiding slipping, idling and slow progress in dense hard rock. Compared with ordinary 3-inch hammers, its hard rock drilling efficiency is increased by more than 30%, greatly shortening the construction period of large-scale mine blasting drilling.
3. High-Speed Large-Flow Slag Discharge & Zero Blockage Heavy-Load Operation
The exclusive central exhaust system matched with high-pressure large-flow airflow sprays high-speed concentrated air to instantly take away large rock slag, hard rock debris and dust in the hole, completely avoiding repeated rock crushing, jamming and hole collapse caused by slag accumulation. The hole wall is clean and flat with standard forming specification, no secondary repair required, fully meeting the high-standard blasting hole construction requirements of mines and reducing equipment failure rate during heavy-load operation.
4. Heavy-Duty Forging Process & Ultra-Fatigue Resistance Durability
The whole hammer is integrally forged from military-grade ultra-high-strength alloy steel, eliminating the material defects of ordinary casting and stamping processes. With multiple high-temperature quenching and tempering heavy-duty reinforcement treatments, the body has uniform overall hardness, excellent toughness and strong impact and fatigue resistance. It resists long-term high-frequency super impact, severe hard rock friction and harsh outdoor environment erosion without cracking, deformation, air leakage and wear. Internal precision accessories feature high matching accuracy and smooth stable transmission with extremely low failure rate and longer service life, adapting to 24-hour continuous heavy-load production.
5. National Standard Universal Specification & Lossless Quick Replacement
Manufactured in strict accordance with international general standards for 3-inch high-pressure DTH hammers, all outer diameter, interface, air channel and installation dimensions are fully standardized, 100% compatible with all brands of 3-inch high-pressure drilling rigs and 90-110mm full-series high-pressure drill bits on the market. Old high-pressure hammers with weakened impact, slow drilling, frequent blockage, air leakage and fatigue wear can be directly replaced without air pressure debugging and equipment modification, plug and play, suitable for batch mine equipment maintenance, old equipment renovation and foreign trade equipment supporting.
6. Heavy-Duty High Efficiency & Low Comprehensive Construction Cost
With extreme rock breaking performance, it scientifically matches high-pressure air consumption, adapts to high-power air compressor working conditions with high energy utilization rate and no invalid energy loss. It features stable heavy-load operation, ultra-low failure rate, long maintenance cycle and low consumable loss, greatly reducing downtime maintenance time and replacement cost. For large-scale mine batch drilling construction, it achieves higher comprehensive construction efficiency and lower comprehensive operation cost, serving as a cost-effective and high-performance mainstream tool for heavy-duty hard rock projects.
