Product Description
In both mines and quarries, oversized rock and bridging at the primary station are among the fastest ways to lose tons per hour and push operators into dangerous clearing tasks. YZH stationary rockbreakers are installed on fixed pedestals next to crushers and grizzlies so operators can reach into the feed zone, break and rake problem pieces, and restore material flow without shutting the line for manual work or secondary blasting.
The wide working rotation (often around 170°) allows a single system to cover a broad area at the crusher mouth or grizzly deck, eliminating multiple localized bottlenecks that would otherwise cause repeated short stops.
Oversized boulders and crusher blockages
At primary crushers, big or unusually shaped rocks can choke the feed area or lodge in the chamber, forcing shutdowns and risky clearing efforts.
Stationary rockbreakers position a hydraulic hammer above the blockage so operators can break the boulder into manageable fragments and push material back into a normal flow pattern.
Grizzly feeder and screen hang‑ups
Grizzly feeders and coarse screens often carry rocks that lie across the bars, starving the crusher and creating surges in the circuit.
A boom placed at the grizzly lets the operator knock down and break this oversize from a distance, keeping bar decks clear and throughput steady.
High downtime and unsafe clearing procedures
Traditional methods—manual barring, portable breakers or explosives—are slow, dangerous and inconsistent, increasing downtime and safety risk.
YZH stationary rockbreakers mechanize these jobs so clearing becomes a quick, repeatable remote‑controlled operation, reducing overall downtime and improving safety KPIs.
Descriptions of YZH stationary and static rockbreaker systems highlight a four‑part architecture optimized for heavy-duty use:
Fixed pedestal and boom
A heavy pedestal base is anchored to concrete or structural steel near the crusher or grizzly, carrying a boom built from high-strength alloys and reinforced steel.
Many models offer up to about 170° working rotation, balancing wide coverage with structural stability for continuous breaking work.
Hydraulic breaker (hammer)
A hydraulic breaker sized to rock hardness and typical oversize weight delivers consistent, powerful blows to fracture large or unmanageable rocks efficiently.
YZH static rockbreakers can be configured with different breaker sizes and energy classes to match specific crusher types and production demands.
Hydraulic power unit
Electric-driven power packs supply the oil flow and pressure required by both the boom cylinders and the breaker, with integrated filtration and cooling for severe environments.
High-efficiency hydraulics and optimized fluid paths support rapid impact cycles, helping reduce overall operation time and the length of each clearing event.
Control and safety systems
Systems can be operated locally or remotely, with manual or remote control modes that remove operators from direct exposure to the crusher feed area.
Interlocks and safety interfaces allow the rockbreaker to work in concert with crusher and feeder controls, supporting safe, coordinated plant operation.
According to YZH and related stationary rockbreaker descriptions, these systems are suited for:
Primary crusher blockage clearance: Breaking large boulders obstructing the crusher feed to keep material flowing smoothly.
Grizzly feeder maintenance: Dislodging rocks stuck on grizzly bars and removing oversize safely from a distance.
Aggregate, cement and mining plants: Preventing crusher jams, improving uptime and protecting equipment from damage caused by uncrushable materials.
They are especially beneficial where mobility is limited or where operations run continuously and cannot tolerate frequent stops for manual clearing.
Content from YZH stationary and static rockbreaker pages emphasizes several key benefits:
Improved crusher throughput and reduced downtime thanks to fast, in‑place secondary breaking.
Less manual rock handling, which improves safety and reduces exposure to hazardous areas.
Lower maintenance needs due to durable design and high-quality hydraulic components, reducing life‑cycle costs.
Higher overall operational efficiency, with wide coverage from a fixed position and the ability to operate continuously in harsh conditions.
If oversized rock and crusher blockages are still dictating when your mine or quarry runs, YZH stationary rockbreakers can turn those critical points into efficient, remote‑operated oversize control stations.
Share your crusher and grizzly layouts, material characteristics and downtime challenges, and YZH will configure a stationary rockbreaker solution focused on reducing interruptions and raising your plant’s effective output.
