Product Description
Primary crushing circuits are rarely limited by average rock size; they are limited by the few pieces that are too big, too long, or too tough for the crusher opening or grizzly spacing. The fixed hydraulic rockbreaker is installed so its hammer can reach those exact locations—inside the crusher throat, on top of the bridged rocks, or on the grizzly bars—allowing operators to shatter or dislodge the offending pieces without stopping the plant for extended manual work.
Rather than treating oversize as an unpredictable crisis, your team treats it as a short, controlled action carried out from a safe station, with consistent procedures and predictable results.
Oversize that standard equipment cannot pass or crush cleanly
Boulders and slabs that exceed the crusher opening or span across grizzly bars can choke the system and force shutdowns.
The fixed hydraulic rockbreaker allows operators to apply focused impact energy directly to these pieces until they fragment to a size that passes easily, preventing choke and recirculation problems.
Unsafe, inefficient manual rockbreaking practices
Without a fixed station, many operations rely on bars, portable breakers, or excavators working on the edge of hoppers, exposing personnel to falling rock, flyrock, and unstable piles.
With a pedestal-mounted rockbreaker and remote or cabin control, oversize is handled from outside the danger zone, enabling strict “no human entry” rules during rockbreaking.
Hidden cost from repeated choke–clear cycles
Each blockage event reduces effective capacity and increases stress on crusher drives, liners, and structures.
Breaking trouble pieces quickly at the source keeps the crusher closer to steady-state operation, extending component life and improving cost per processed ton.
The fixed hydraulic rockbreaker is part of a complete station that typically includes:
Pedestal base and mounting
A rigid pedestal or base is anchored to concrete or structural steel near the crusher or grizzly, providing the stability necessary to transmit high impact forces safely.
The boom or support structure attached to the pedestal is designed so that the hammer can reach all key blockage locations within its working radius.
Hydraulic rockbreaker (hammer)
A heavy-duty hydraulic breaker sized to expected rock hardness, maximum lump size, and duty cycle delivers consistent impact energy to break the toughest boulders.
The hammer, tools, and mounting arrangement are engineered to focus energy into the rock while minimizing unintended contact with crusher frames or grizzly beams.
Electric-hydraulic power pack
A dedicated power unit, driven by an electric motor, supplies hydraulic flow and pressure to the rockbreaker and any associated boom functions.
Cooling and filtration components maintain oil quality under continuous impact duty, supporting long equipment life and stable performance.
Control system and safety interface
Operators can run the rockbreaker from a protected control station or via radio remote, with intuitive controls for firing patterns and positioning where required.
The rockbreaker station can be integrated into plant interlocks and emergency stop systems, ensuring safe coordination with crusher and feeder operation.
While some YZH products integrate boom and rockbreaker into one named model (such as WHA‑series fixed rockbreaker booms), this Fixed Hydraulic Rockbreaker page can emphasize the hammer station as the core impact solution within a broader system.
This type of fixed rockbreaker is especially effective at:
Primary jaw and gyratory crushers handling hard, blocky run‑of‑mine ore where occasional extreme oversize is inevitable.
Grizzly feeders above crushers, where long or flat pieces frequently span bar gaps and must be broken or knocked through.
Ore passes, chutes, and transfer points that experience intermittent blockages from large lumps or tramp material, but where space is too limited for mobile equipment.
In each of these cases, the fixed hydraulic rockbreaker creates a consistently available, purpose-built impact point instead of relying on ad hoc tools and methods.
Although listed as a “Fixed Hydraulic Rockbreaker,” the final installation is engineered around each plant’s layout and duty:
Engineers analyze crusher/grizzly drawings, opening dimensions, typical rock size distribution, and required throughput to determine the correct breaker size and mounting position.
Boom geometry or support structures are configured so that the hammer can reach all likely hang‑up locations with adequate clearance and safe stand‑off from structures.
Power supply, control integration, and structural loads are specified so the station can be installed and commissioned efficiently, whether in a new build or retrofit project.
If needed, the fixed hydraulic rockbreaker can be combined with a fixed or pedestal boom to form a fully integrated fixed rockbreaker boom system as described in YZH’s broader product line.
Developed within a complete family of fixed rockbreaker systems, giving access to proven engineering practices and component choices validated in mines and quarries worldwide.
Focus on durability, safety, and integration ensures the rockbreaker station becomes a long-term asset rather than a temporary fix.
Single-source supply of breaker, structure, and power/control hardware simplifies support, spare parts, and future upgrades across the site.
If oversized rock and manual breaking are still stopping your primary crusher or grizzly, a fixed hydraulic rockbreaker station can turn that high‑risk point into a controlled, engineered impact zone.
Share your crusher or grizzly layout, feed opening, rock characteristics, and production goals, and YZH will design a fixed hydraulic rockbreaker configuration that fits your plant and delivers predictable, safe oversize control shift after shift.
