YZH
Product Description
This static rockbreaker boom system is designed as a permanent part of your primary crushing or grizzly installation, not an add‑on tool. Positioned next to the crusher mouth or feeder, the boom reaches into the hopper or grizzly bars to break and clear oversize boulders, bridging, and hang‑ups before they shut your plant down.
YZH engineers each system around your specific crusher type, feed arrangement, and rock characteristics to ensure the boom envelope covers all critical blockage zones.
Eliminates dangerous manual clearing
Removes the need for workers to enter the crusher station with crowbars or mobile breakers, significantly reducing exposure to falling rock and confined-space hazards.
Remote or cabin control allows all breaking and raking tasks to be handled from a safe location outside the danger zone.
Removes blockages and bridging quickly
Breaks oversize rock at the grizzly, crusher mouth, or chute entry to prevent bridging that chokes your feed.
Clears hang‑ups in stationary and mobile crushers, restoring full opening and maintaining design throughput.
Stabilizes production and reduces downtime
Converts unplanned stoppages caused by oversize and frozen ore into short, controlled breaking cycles.
Reduces start/stop wear on crushers, improving liner life and reducing emergency maintenance interventions.
Each static rockbreaker boom system is delivered as a complete, integrated package matched to the duty:
Pedestal and rotating upper structure
Heavy-duty base with swivel console or rotating frame, providing wide slewing angles to cover the full hopper and surrounding area.
Designed to be mounted on concrete or steel structures according to your civil layout.
Lift boom and arm with hydraulic breaker
Multi-section boom geometry offers long horizontal reach and deep vertical penetration into the crusher pocket.
Compatible with leading hydraulic breaker brands (e.g., RAMMER, Indeco, Krupp) sized to your rock hardness and fragmentation.
Hydraulic power unit and controls
Dedicated hydraulic station with motor drive, oil filtration, cooling, and monitoring of pressure, temperature, and oil level.
PLC-based control with local console and optional radio remote control for precise boom and hammer operation.
Typical parameters for a small–medium YZH static boom (e.g., BHB450/BHB600) include boom weights around 3–3.5 t and horizontal reach in the 6.9–8.3 m range, giving ample coverage for standard primary crushers and grizzlies.
The static rockbreaker boom system is suitable for:
Primary jaw and gyratory crushers in quarries and open‑pit mines that frequently see oversize or irregular feed.
Stationary and mobile grizzlies where large boulders bridge on the bars and stop material flow.
Underground mine ore passes, drawpoints, and fixed chutes where manual barring is high risk.
Heavy industrial applications where large, solid pieces (slag, scrap, refractory) must be safely broken before further handling.
Instead of selling a generic boom, YZH positions this static rockbreaker boom system as a tailored solution:
Site survey of crusher type, opening size, installation height, rock size distribution, and required working envelope.
Selection of boom series (small, medium, heavy-duty), breaker size, pedestal design, and slewing configuration to match your production targets and budget.
Integration support including layout drawings, foundation guidance, and interface with plant electrical and control systems.
Optional features such as extended boom reach, heavy-duty designs for very hard rock, low-temperature packages, and enhanced dust protection can be specified for demanding environments.
Focused expertise in pedestal rockbreaker boom systems for mining and aggregates, with global references and continuous product development.
Broad range from compact static booms for small quarries to large, long-reach systems for high-capacity primary crushers.
Reliable components, CE-compliant design, and lifecycle service support to keep your system productive over many years of operation.
If your primary crusher or grizzly is causing bottlenecks, safety incidents, or frequent stoppages due to oversize, a static rockbreaker boom system can be engineered as a dedicated solution to stabilize your process.
Share your crusher type, opening dimensions, feed characteristics, and target throughput, and YZH’s engineering team will design a customized static rockbreaker boom solution that fits your layout and long-term production goals.
