Product Description
On busy mining sites, oversize boulders and blocked feed zones are a primary cause of crusher stoppages and unsafe clearing tasks. B Series static rockbreakers are positioned at these bottlenecks—mounted on fixed pedestals next to crushers, grizzlies or ore chutes—so operators can break and rake problematic rock where it sits, restoring flow without sending people into hazardous areas.
Because the systems are static and dedicated to one location, their boom reach, hammer capacity and hydraulic performance can be tuned precisely to the site’s ore and layout, improving both reliability and breaking efficiency.
Oversized rocks and crusher blockages
Run‑of‑mine ore often contains large or irregular pieces that cannot pass the crusher opening or that wedge in the chamber, causing unplanned shutdowns.
B Series static rockbreakers apply targeted impact to these pieces at the feed area, reducing them to manageable sizes and pushing fragments into the crusher so production can resume quickly.
Grizzly and ore chute hang‑ups
Grizzly screens and ore chutes are prone to bridging, where rocks arch over openings and cut off flow to downstream equipment.
A B Series boom placed at these points lets the operator dislodge and break the material from a safe distance, keeping bar decks and chutes clear.
High downtime and unsafe manual rockbreaking
Without static rockbreakers, mines may rely on manual bars, small tools or mobile machines working close to open hoppers and chutes, raising risk and consuming time.
Static rockbreakers mechanize these tasks under remote or cabin‑based control, shortening clearing times and removing people from high‑risk zones.
The product description and related YZH pages emphasize durability and continuous‑duty capability:
Durable pedestal and boom structure
Each static rockbreaker uses a stout pedestal, powerful boom and hydraulic hammer to deliver precise impact while resisting the stresses of continuous heavy use.
Heavy‑duty construction with high‑strength steel, reinforced welds and wear‑resistant bushings ensures stability and longevity under extreme conditions.
Continuous operation and flexible control
B Series static rockbreakers are designed to operate continuously in mining, quarrying and aggregate processing environments.
Systems can be controlled manually at a local console or via remote controls, enhancing operator safety by eliminating the need for direct contact with dangerous areas.
Sized and configured for different crushers and duties
B Series units are available in multiple sizes and configurations to match different crusher types, grizzly geometries and production requirements.
By selecting the right boom reach, hammer capacity and hydraulic package, mines can align each static rockbreaker with the duty at its specific station.
For the BB450 model noted on the product page, typical working envelope data include:
Max. horizontal working radius: 7,000 mm
Max. vertical working radius: 4,950 mm
Min. vertical working radius: 2,040 mm
Max. working depth: 4,890 mm
Rotation: 170°
This envelope allows operators to:
Reach across the crusher mouth, over grizzly bars or into an ore chute to handle oversize at multiple points around the station.
Sweep a broad arc without relocating the pedestal, thanks to the 170° rotation.
As described across YZH’s rockbreaker literature, B Series durable static rockbreakers are suitable for:
Primary crusher stations in open‑pit or underground mines where continuous and safe oversize control is essential.
Grizzly screens, ore chutes and transfer points where oversize or tramp material regularly creates hang‑ups.
Aggregate and cement operations needing a fixed, low‑maintenance tool to protect crushers from uncrushable materials.
Key benefits include improved crusher throughput, fewer stoppages, reduced manual rock handling, and lower maintenance requirements due to their durable design and high‑quality hydraulic components.
If your mining site is still losing production to oversized rocks and blocked feed points, YZH B Series durable static rockbreakers can turn those locations into engineered oversize‑control stations.
Share your crusher, grizzly or chute layout, material characteristics and production targets, and YZH will configure a B Series static rockbreaker—such as the BB450—with the boom reach, breaker size and hydraulics matched to your mining site.
