BB430
YZH
Product Description
This static rockbreaker system is engineered as a fixed solution for primary crushing stations, underground drawpoints, and grizzly feeders where oversized rock frequently causes costly stoppages.
Installed on a pedestal adjacent to the crusher or grizzly, the boom reaches into the feed opening to break, rake, and clear obstructive material without sending personnel into hazardous areas.
Eliminates crusher blockages
Breaks oversize boulders before they enter the crusher, preventing bridging at the hopper, jaws, or grizzly.
Maintains smooth, continuous material flow so you can run at planned capacity instead of stopping for manual clearing.
Maximizes uptime and productivity
Reduces unplanned shutdowns caused by large rock, frozen ore, or tramp material at the primary station.
Designed for continuous-duty operation in three-shift mines and high-throughput quarries, supporting long production campaigns.
Improves operator safety
Allows rock breaking, raking, and clearing to be performed from a safe distance via cabin or radio remote control.
Minimizes exposure to falling rock, flyrock, and confined spaces around the crusher mouth or grizzly.
Reduces maintenance and total cost of ownership
Breaking oversize at the face of the crusher protects liners, jaw faces, and other wear parts from impact damage.
Robust boom design and optimized hammer sizing reduce stress on both the rockbreaker and the crusher, lowering repair and service costs.
Each static rockbreaker system is delivered as a complete, integrated package matched to your application:
Pedestal-mounted hydraulic boom (e.g., BB430) with long horizontal reach (up to 6770 mm) and generous vertical coverage for full access to the crusher opening.
High-performance hydraulic breaker sized to your rock hardness, feed fragmentation, and required breaking duty.
Hydraulic power pack and control valves designed for reliable operation in harsh mining and quarry environments.
Local control console and optional radio remote control for precise, safe boom and hammer operation.
For the BB430 configuration, the system offers:
Max. horizontal working radius (R1): 6770 mm
Max. vertical working radius (R2): 4710 mm
Min. vertical working radius (R3): 1640 mm
Max. working depth (H2): 4710 mm
Slew rotation: 170°
These ranges allow the boom to reach deep into the crusher or grizzly, as well as clear surrounding build-ups and hang-ups.
The static rockbreaker system is suitable for:
Primary jaw and gyratory crushers in open-pit mines and large quarries.
Static or mobile grizzly installations handling run-of-mine (ROM) ore and oversized rock.
Underground mine ore passes and drawpoints where manual barring presents high risk.
Heavy industrial plants, foundries, and steel mills needing safe, fixed breaking of large scrap or refractory material.
Instead of offering a one-size-fits-all product, YZH provides a solution engineered around your site:
Site-specific assessment of crusher type, feed arrangement, rock characteristics, and required breaking envelope.
Proposal drawings showing pedestal location, boom reach coverage, and interaction with the crusher or grizzly.
Selection of boom model, hammer size, rotation type, and control options to meet your throughput and safety targets.
For special conditions (limited headroom, underground installation, extreme climate, or abrasive ore), the system can be configured with tailored boom geometries, pedestal designs, and protection packages.
Proven supplier of pedestal rockbreaker boom systems for the global mining and aggregates industry since 2002.
Full portfolio from compact units for small quarries to extra-heavy-duty systems for large primary crushers and grizzlies.
CE-certified equipment, backed by engineering support, commissioning guidance, and lifecycle service.
If your primary crusher or grizzly is suffering from oversize blockages, safety incidents, or frequent manual clearing, this static rockbreaker system can be engineered as a dedicated solution to stabilize your operation.
Share your crusher layout, throughput targets, and typical rock size, and YZH’s engineering team will design a customized static rockbreaker system that fits your site and unlocks higher productivity and safer working conditions.
