BB600
YZH
Product Description
Quarry grizzlies are designed to scalp off big rock, but boulders and flat slabs often lodge across the bars, starving the crusher and forcing crews to stop and clear the deck. YZH fixed pedestal rockbreakers put a dedicated boom and breaker directly over the grizzly, so operators can knock down and break these pieces in seconds, instead of sending people with bars or bringing in a loader bucket.
This turns the grizzly from a chronic bottleneck into a controlled oversize‑management point, improving throughput and protecting the vibrating equipment from shock loading.
Quickly clears blocked bar decks
When large or uncrushable rocks sit on top of the grizzly, the BB600 rockbreaker reduces them in place so smaller fragments pass through and the crusher keeps feeding.
Maintains steady material flow
By dealing with oversize before it builds into a full blockage, the system helps the grizzly deliver a more uniform flow to the crusher, cutting peaks, dips and unplanned stops.
Improves operator safety
Instead of working close to a live grizzly and moving rock by hand, operators use boom controls from a protected station or remote, staying out of the hazard zone.
Protects the grizzly and reduces maintenance
Breaking and raking oversized rock in a controlled way reduces impact shocks and mechanical abuse on the grizzly structure, extending its life and lowering maintenance effort.
Custom fit for each grizzly layout
Boom geometry and pedestal placement can be adjusted so BB600 covers the full bar area and the typical rock pile, matching each quarry’s layout and feed conditions.
According to YZH’s fixed and static rockbreaker descriptions, BB600 fixed pedestal rockbreakers comprise four main elements:
Pedestal boom
A welded steel boom mounted on a pedestal base anchored beside or behind the grizzly, designed for high stiffness and long service in abrasive quarry conditions.
Hydraulic hammer (breaker)
A matched hydraulic breaker at the boom tip provides the impact force to fracture large rocks and stubborn slabs resting on the grizzly bars.
Hydraulic power unit
An electric-driven hydraulic pack supplies oil flow and pressure to both boom cylinders and the breaker, with filtration and cooling sized for continuous quarry duty.
Control system
Local or remote controls give the operator smooth, proportional control of swing, lift and breaker functions, allowing precise positioning over individual grizzly bars.
BB600 provides a wide coverage window tailored to grizzly work:
Max. horizontal working radius (R1): 8,430 mm
Max. vertical working radius (R2): 6,330 mm
Min. vertical working radius (R3): 2,300 mm
Max. working depth (H2): 5,810 mm
Rotation: 170°
These dimensions allow the boom to:
Reach across the full grizzly deck and into the rock pile feeding it.
Work both close to the grizzly bars and deeper into the feed zone or rockbox without repositioning the pedestal.
BB600 fixed pedestal rockbreakers for grizzly in quarries are ideal for:
Primary grizzly feeders ahead of jaw or impact crushers, where large boulders need to be broken or knocked through before crushing.
Stationary quarry installations where a single boom must cover a wide grizzly and adjacent rockbox area.
By combining a long‑reach, 170° rotating boom with a powerful breaker and robust pedestal base, YZH BB600 gives quarry operators a reliable tool to keep grizzlies clear and crushers supplied with correctly sized rock.
