Product Description
In mining, smooth operation depends on keeping ore moving from the face to the plant without long pauses for clearing blocked crushers or choked grizzlies. YZH fixed rock breaker booms are installed exactly where oversize tends to cause trouble—at crusher mouths, over grizzlies or near rockboxes—so operators can break and rake problematic rock before it stops the line.
Because the boom is permanently mounted and always ready, operators do not need to wait for mobile equipment or explosives, which helps shift leaders maintain consistent output across the entire operation.
Oversize and bridged rock at crushers
Large boulders, hard inclusions or slabby rocks can sit across the crusher inlet or jam the chamber, starving the plant and increasing stress on mechanical components.
The fixed rock breaker boom swings in, places the hammer on the obstruction and fractures it into manageable sizes, then rakes fragments into the crusher so normal feed can resume.
Grizzly hang‑ups and blocked rockboxes
Grizzly bars and dump pockets often collect oversize or odd‑shaped pieces that bridge openings and interrupt ore flow to crushers or conveyors.
With a fixed boom over or beside the grizzly, operators can knock down, break and pull material through without sending people onto the deck or into the pocket.
High downtime and unsafe manual clearing
Manual barring, small handheld breakers or repeated secondary blasts are slow and expose personnel to falling rock and unstable piles.
A fixed rock breaker boom mechanizes these tasks under remote or protected control, sharply reducing both downtime and exposure to high‑risk areas.
YZH’s fixed rock breaker boom solutions share a common structure described for its fixed and static systems:
Fixed base and boom structure
The lower frame is firmly fixed to a concrete or steel base near the crusher or grizzly, providing a solid foundation for the rotating upper frame and boom.
Booms are fabricated in high‑tensile steel with oversized pins and reinforced sections to withstand millions of breaking and raking cycles in abrasive mining environments.
Hydraulic breaker (hammer)
A hydraulic breaker sized to the rock hardness and maximum lump size is mounted at the boom tip, delivering the energy needed to fracture boulders, slag or ore.
Breaker selection is matched to the specific mining duty—light, medium or heavy—so the system stays efficient without overstressing the structure.
Hydraulic power unit
Electric-driven power units supply pressurized oil to both boom cylinders and breaker, with filtration and cooling sized for constant or multi‑shift operation.
Power ratings and flow/pressure values are chosen according to boom size and breaker class to ensure responsive, reliable performance.
Control and safety systems
Operators use local consoles or remote controls with joysticks to move the boom and fire the breaker, allowing fine control while staying out of the immediate danger zone.
Integration with plant safety (interlocks, emergency stops) ensures the rockbreaker works in sync with crusher and conveyor control logic.
YZH fixed rock breaker booms for seamless operation are suitable for multiple points in a mining flow:
Primary jaw, gyratory or impact crushers where a fixed breaker station is required to maintain continuous feed and avoid choke events.
Grizzly feeders, rockboxes and surge pockets in open‑pit or underground operations where oversize frequently bridges openings and must be broken on the spot.
Transfer chutes and secondary crushing stations where occasional large lumps can halt material flow and require rapid, safe intervention.
These stations are especially valuable in high‑tonnage mines, where even short interruptions have significant cost impacts.
Although described generally as a “fixed rock breaker boom for seamless operation in mining site,” each installation is engineered around the site layout and duty:
YZH engineers review crusher or grizzly drawings, access constraints, rock properties and production targets to specify boom length, rotation, breaker size and base location.
Coverage studies ensure the boom can reach all expected hang‑up points and work within structural and clearance limits, before foundations and supports are finalized.
Hydraulic, electrical and control details are coordinated with mine standards so the system can be installed and commissioned with minimal disruption.
If oversize and unplanned stoppages are still disrupting your mining site, a YZH fixed rock breaker boom can turn key points in your flow into engineered oversize‑management stations that support seamless operation.
Share your crusher, grizzly or rockbox layout, typical ore size distribution and throughput goals, and YZH will propose a fixed rock breaker boom configuration tailored to your mining site
