When working in high-production mining and quarry operations, the BLT-165 hydraulic breaker is specifically engineered to handle hard rock excavation, secondary breaking, and continuous heavy-duty demolition.
Mounted on 30 to 45-ton excavators, the 165 mm chisel diameter provides the high impact energy needed to fracture high-strength granite, basalt, and reinforced concrete.
Key Specifications & Operational Parameters
Tool / Chisel Diameter: 165 mm
Applicable Excavator Carrier: 30 – 45 Tons
Impact Rate: ~300 – 500 BPM (beats per minute)
Required Hydraulic Oil Flow: ~220 – 290 L/min
Operating Pressure: ~160 – 180 Bar
Recommended Features for Mining & Quarry Applications
Sound Suppressed (Box-Type) Housing: Protects the internal main body from falling rock debris, significantly dampens job-site noise, and reduces vibration feedback to the excavator boom.
Auto-Greasing System (AG Unit): Essential for continuous quarry operation. Automatically lubricates the front bushings and chisel to prevent metal-on-metal friction and premature wear.
Dust Suppression / Underwater Port: Allows connection to air and water lines to clear dust particles during dry quarrying or prevent internal damage during underwater dredging work.
Heavy-Duty Chisel Options: Pair with a Conical/Moil Point for initial rock fracturing or a Wedge/Chisel Point for stratified rock splitting.
Best Operational Practices in Heavy Quarrying
Avoid Blank Firing: Never trigger the breaker without firm tool contact against the rock; blank firing damages internal tie-rods, retaining pins, and front bushings.
20-Second Rule: Stop hammering after 20 continuous seconds in the same spot. Move the chisel point to a new fracture line to prevent excessive heat buildup.
Daily Inspections: Check nitrogen accumulator pressure and verify that automatic lubrication channels are flowing freely before every shift.
