Oversized rocks, often called big rocks or boulders on site, entering crushers and feeders are one of the most common causes of unplanned shutdowns in mining and quarry operations. A single boulder can block a crusher inlet, overload wear parts, or force rock-breaker intervention \u2014 turning normal production into an emergency.<\/p>

The oversized rock and boulder detection system continuously monitors material on conveyors, at dump pockets, and under haul-truck discharge. It detects oversized rocks in real time and triggers alarms or control actions before a boulder reaches critical equipment.<\/p>

This system is designed for real-time primary crusher feed protection in mining and quarry operations. A detailed explanation of how and where this detection is implemented is provided in the Installation & Sensing Technology<\/strong> <\/a>section.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

What the system does<\/h3>

The oversized rock and boulder detection system performs three core functions:<\/p>

  1. Measures rock size in motion<\/strong>
    Industrial cameras analyse material as it moves or is dumped, identifying individual rocks and estimating their size in real time.\u00a0<\/li>
  2. Classifies oversized and big rock material<\/strong>
    Rocks that exceed configured limits are identified as boulders before they reach critical equipment.\u00a0<\/li>
  3. Triggers plant response<\/strong>
    When a boulder is detected, the system can alert operators, stop or isolate feed via PLCs, and issue SMS or phone-call notifications to on-shift personnel.<\/li><\/ol>

    This turns uncontrolled crusher disruptions into controlled process events, reducing unplanned downtime, wear-part damage, and maintenance cost. The full operational and financial impact of oversized rocks is detailed in the Prevent Crusher Downtime<\/strong><\/a> section.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Why this matters<\/h3>

    Crushers and feeders are designed for a defined maximum feed size. When oversized rocks enter the system, they lead to:<\/p>
