BB450
YZH
Product Description
In high-tonnage crushing circuits, every unscheduled stop costs money, and most of those stops come from the same place: oversize and hang‑ups at the crusher and hopper. The BB450 pedestal rockbreaker boom system is installed as a permanent “tool arm” for that station, giving operators the ability to break bridged rock in the crusher throat and manage the burden in the hopper without moving mobile equipment into tight spaces.
With its wide working radius and deep reach, the BB450 is sized so that a single installation can cover all the key trouble spots around typical primary crushers and feed hoppers.
Keeping tons per hour up in tough conditions
Mines and quarries operate on throughput, and any blockage at the primary crusher directly hits the bottom line.
The BB450 allows operators to react immediately to oversized boulders and bridging, using the rockbreaker boom to restore flow before the line drops significantly below target production.
Safety and exposure around the crusher and hopper
Manual clearing with bars or bringing excavators close to open hoppers exposes crews to falling rock, flyrock, and unstable piles.
The pedestal-mounted BB450 is controlled from a safe location via remote or local console, allowing “no entry” rules in the danger zone during rockbreaking and material manipulation.
Variable fragmentation and changing feed profile
Even well-controlled blasting can produce long, flat or irregular rocks that do not flow smoothly through the hopper and crusher.
Using the boom to pull down arches, spread material, and break awkward pieces, operators can maintain a more consistent feed pattern, improving crusher performance and liner life.
The YZH BB450 pedestal rockbreaker boom system is supplied as a complete station:
Pedestal-mounted boom
A robust pedestal supports the boom structure and slewing mechanism, anchored to concrete or structural steel adjacent to the crusher/hopper.
The BB450 boom provides:
Max. horizontal working radius (R1): 7000 mm
Max. vertical working radius (R2): 4950 mm
Min. vertical working radius (R3): 2040 mm
Max. working depth (H2): 4890 mm
Rotation: 170°
This envelope allows the operator to sweep across the crusher mouth, reach deep into the pocket, and work over the hopper surface from one mounting point.
Hydraulic hammer (breaker)
A compatible hydraulic hammer is mounted on the boom and sized for the site’s rock hardness and maximum lump size, delivering the impact energy needed to break stubborn boulders.
The boom and hammer are engineered together so the operator can strike effectively while minimizing risk to crusher frames and hopper structures.
Hydraulic power unit with electric motor drive
An electric motor-driven hydraulic power unit supplies stable flow and pressure to the boom and breaker, with filtration and cooling designed for continuous-duty operation in dusty, high-load environments.
Electric drive keeps operating costs lower than diesel-driven mobile solutions and simplifies integration into plant utilities.
Operating control and remote capability
The system includes an operating control suite, typically with local console and remote control options, enabling safe, precise boom movements and hammer operation.
Remote operation makes it possible to keep personnel out of the immediate crusher/hopper area during rockbreaking, supporting modern safety standards and site procedures.
The BB450 is particularly suited to:
Primary jaw crusher stations in mid-size to large quarries and metal mines where one boom can cover both crusher mouth and hopper.
Grizzly-equipped feed hoppers handling run-of-mine ore or blasted stone where flat or oversized rocks frequently hang up on the bars.
Central aggregate crushing plants where high utilization and long shifts demand a robust, field-proven boom system to keep the line moving.
Its reach and rotation make it a flexible solution for many layouts, especially where quick access to both crusher and hopper is critical.
While the BB450 has defined geometry and reach, YZH treats each installation as a project to be engineered, not just a product drop-in:
Site engineers review crusher and hopper drawings, elevations, and available foundations to confirm that the BB450’s working envelope fully covers the identified blockage zones.
Hammer size, power unit configuration, and control options are chosen based on rock characteristics, duty cycle, and operator preferences (cabin vs. remote, integration with plant PLC, etc.).
Optional equipment and customization—such as special mounting structures, additional protection for dust and impact, or advanced remote solutions—can be added to align with specific site requirements.
YZH is recognized as a leading supplier of pedestal rockbreaker boom systems with field-proven packages running in mines and quarries worldwide.
Broad model range (including BB450 and larger/smaller booms) allows each crusher and hopper on a site to be matched with an appropriately sized system, improving overall cost effectiveness.
Focus on reliability, safety, and lifecycle support means the pedestal rockbreaker boom system becomes a long-term productivity tool, not just a short-term blockage fix.
If your crushing line is losing tons per hour to oversize rock, hopper hang‑ups, or unsafe clearing methods, a BB450 pedestal rockbreaker boom system can turn that weak point into a controlled, high-availability station.
Share your crusher and hopper layout, typical rock size, and production targets, and YZH will engineer a BB450-based pedestal rockbreaker boom system—or an alternative size from the range—that fits your plant and supports safe, continuous output.
