High-Energy Impact Crushing Action for Massive Boulder Secondary Breaking
The Blunt Tool (also widely classified as a Blunt Chisel or Flat Demolition Block) is a massive, flat-faced working steel precision-engineered for the monumental Atlas Copco HB 10000 series hydraulic breaker. Operating on ultra-heavy 85 to 140-ton carrier class excavators, this hammer generates unprecedented kinetic energy per single impact. Unlike sharp pointed bits that pierce materials, the blunt tool works by transmitting massive, devastating stress shockwaves directly into highly abrasive, hard rock boulders and slag blocks. This broad compression wave shatters the internal crystal structures of the material, making it the premier choice for secondary breaking without generating excessive dust or tool deflection.
MERIT manufactures this elite replacement blunt steel utilizing vacuum-degassed, high-density forged alloy structural steel. Refined through specialized deep-thermal induction tempering and rigid cross-sectional heat treatment, our heavy tools maintain excellent dimensional stability, eliminate premature face mushrooming, and completely resist internal fatigue fracturing under maximum impact frequencies.
Technical Features and Metallurgical Precision of MERIT Heavy Blunt Tools
Managing the brutal mechanical rebounding forces produced by a 10-ton class breaker striking hard granite requires uncompromised steel density. MERIT ensures field reliability through:
1. Unified Heavy-Impact Deep Case Hardening
Our proprietary multi-stage thermal cycle treats the striking face to withstand extreme localized friction and compressive stress. The ultra-dense exterior face resists rapid wear when breaking highly abrasive quarry rock and dense mountain matrices, while the elastic core matrix prevents catastrophic cracking.
2. High-Precision Retainer Slot Alignment
The massive dual retainer pin tracks are CNC-milled to exact original engineering tolerances. This perfect alignment significantly restricts excessive vertical and rotational free-play inside the lower front head housing, protecting the heavy locking pins and inner chuck bushings from premature fatigue wear.
3. Maximum Resistance to Blank Firing Stress
Secondary rock breaking often leads to sudden material collapse, causing unavoidable blank fires. MERIT blunt tools feature an elevated fatigue threshold designed to safely dissipate these damaging rebound shockwaves throughout the tool shank rather than developing dangerous micro-fractures.
Primary Industrial Applications
- Secondary Rock Breaking: Crushing oversized boulders in quarry drop-balls and open-pit mining operations following primary blasting.
- Mass Infrastructure & Port Development: Breaking down heavy coastal rock formations, massive marine concrete blocks, and dense foundations for deep-water port expansions.
- Monolithic Civil Demolition: Crushing massive reinforced concrete bridge piers, heavy marine seawalls, and industrial bunker structures.
