Efficiency in Marble & Granite Quarries: Heavy Duty Breaker Selection

Marble and granite quarries present the toughest test for machinery and attachments. Hard ground, constant impact, and dust can turn standard equipment into scrap in no time.

The key to profitability in quarries is minimizing downtime.

1. Why is Heavy Duty Breaker Essential?

Breakers in quarries operate 10-12 hours non-stop. Standard series breakers overheat and seize under this tempo.

• Reinforced Body: Heavy Duty series are armored with Hardox plates against the abrasive effect of stone.
• Extra Cooling: They feature wider oil channels and optional water/air cooling systems to prevent overheating.

2. Correct Tool Selection for Marble

Wrong tool selection reduces production speed by 30%.

• Blunt Tool: Best for cracking block marble with shockwaves without drilling into the stone.
• Chisel Tool: Used for separating veined rocks and during the overburden removal stage.

Frequently Asked Questions (FAQ)

Q: Is auto-lubrication necessary in marble quarries?
A: Absolutely. Quarries are very dusty environments. Manual greasing risks pushing dust into the system. A closed-loop auto-lube system extends breaker life by 50%.

Q: Membrane vs. Piston Accumulator?
A: Membrane types react faster for marble quarries requiring continuous rapid strikes. However, piston types are more economical maintenance-wise. HKM offers both.
