Product Description
At primary and secondary breaking stations, oversize rock and flow interruptions on grizzlies, ore passes and crusher mouths are major constraints on throughput and safety. YZH stationary rock breaker systems are installed at these points to provide precise, explosive‑free breaking and raking, keeping material moving and crews away from open jaws and unstable piles.
Rather than treating blockages as emergencies that require ad‑hoc blasting or mobile machines, the rock breaker station becomes a permanent part of the circuit, designed around the plant’s geometry and production targets.
Oversize that chokes crushers and grizzlies
Large or tough rocks can hang in crusher jaws, sit in rockboxes or bridge across grizzly bars, starving the line and forcing shutdowns.
The stationary system positions a hydraulic breaker on a boom so operators can break and rake these pieces where they sit, restoring flow without secondary blasting.
Dangerous manual clearing and material slinging
Before stationary systems were common, workers often had to dislodge jammed rock manually or sling oversize out of rockboxes, exposing them to flyrock and falls.
With YZH’s solution, breaking and material manipulation are done from a remote console or protected cabin, removing personnel from the immediate hazard zone.
Unpredictable downtime and low utilization
Each unplanned blockage event slows the entire crushing or conveying chain, increasing energy use per ton and reducing equipment life.
A dedicated rock breaker station lets operators handle oversize quickly and consistently, supporting continuous or near‑continuous operation in mines and quarries.
YZH stationary rock breaker systems are built around four main elements, consistent with industry definitions of rockbreaker boom systems:
Pedestal boom
The boom (arm) is mounted on a pedestal or slew frame fixed to a foundation near the crusher, rockbox or grizzly and is designed to reach all critical hang‑up points.
High‑tensile steel, oversized pivots and reinforced sections allow the boom to withstand millions of raking and breaking cycles in abrasive environments.
Hydraulic breaker (hammer)
A hydraulic breaker sized to rock hardness and lump size provides the impact needed for secondary breaking and clearing, replacing explosives in many applications.
It is configured so that impact energy is directed into the rock, not the crusher frame or supporting structure.
Hydraulic station (power unit)
An electric-hydraulic power unit supplies oil flow and pressure to both boom and breaker, with filtration and cooling suitable for continuous-duty operation.
This centralized unit simplifies maintenance compared with multiple small power packs or mobile machines.
Control system
The controller allows operators to manipulate the boom and breaker from a safe location; modern systems can integrate with plant PLCs for interlocks and monitoring.
Options range from straightforward local panels to advanced remote controls and video-assisted operation around the crusher cavity.
YZH stationary rock breaker systems are used across:
Crushing plants – At stationary and portable plants for raking and breaking oversize so only appropriately sized rock reaches primary and secondary crushers.
Grizzlies, rockboxes and ore passes – On grizzlies and ore passes to prevent oversize bridging and to maintain material flow without exposing workers to hazardous openings.
Mining, quarrying, coal and cement – For secondary breaking and lump reduction in open‑pit and underground mines, coal yards and cement raw material handling.
The experienced rockbreaker team at YZH provides site-specific assessments and proposal drawings to ensure that each station is positioned for optimum safety, reliability and productivity.
Although marketed under a common “YZH Stationary Rock Breaker System” name, each installation is customized:
Boom reach, breaker size, pedestal position and swing range are selected based on site drawings, material properties and required duty.
Systems can be configured for underground or surface use, for continuous 24/7 operation, and for integration into existing control architectures.
If oversize, grizzly hang‑ups or ore pass blockages are still limiting your throughput, a YZH stationary rock breaker system can turn those weak points into engineered, remote‑operated stations.
Share your crusher, grizzly or ore pass layout, material type and production targets, and YZH will design a stationary rock breaker configuration tailored to your plant and safety requirements.
