Product Description
Oversized rock and bridged material are among the main reasons primary crushers run below capacity, yet those problem pieces represent only a small fraction of the total feed. The YZH Fixed Rockbreaker gives your operation a dedicated impact point at the crusher mouth or grizzly, so those few critical rocks can be broken down quickly without stopping the plant for dangerous and time‑consuming manual work.
Instead of treating oversize as an exception, you treat it as an expected event handled by a fixed breaking station that is always in place, always powered, and always reachable from a safe control position.
Stubborn oversize and bridging at primary intake
Large boulders, slabby blocks, or frozen ore can lodge in the crusher cavity or span across grizzly apertures, blocking the entire feed.
The Fixed Rockbreaker applies focused impact force directly to these pieces, fragmenting them into smaller rock that passes easily into the crusher or through the grid.
Unsafe and inefficient manual breaking methods
Without a fixed station, crews may use bars, portable breakers, or excavators near open hoppers, exposing operators to falling rock, flyrock, and unstable piles.
With a pedestal-mounted rockbreaker, operators work from a remote console or cabin, enforcing “no human entry” rules in the danger zone during breaking operations.
Downtime, equipment stress, and lost production
Frequent choke–clear cycles increase wear on crushers, conveyors, and support structures and cause output to fluctuate.
Breaking trouble pieces early and consistently keeps the circuit closer to steady-state operation, improving effective tons per hour and extending component life.
Although the product name highlights the rockbreaker, the YZH Fixed Rockbreaker is conceived as part of a complete stationary breaking station:
Fixed base and support structure
The rockbreaker is mounted on a fixed base, pedestal, or integrated boom system that is firmly anchored to concrete or structural steel next to the crusher or grizzly.
This support structure is designed with wide cross sections, extra-large pins, and high-tensile steel plates to handle the dynamic loads of repeated impact and side loading.
Hydraulic breaker (rock hammer)
A high-efficiency hydraulic breaker is selected for each installation based on rock hardness, maximum lump size, and duty cycle, providing enough impact energy for rapid reduction.
Tool and mounting configuration are chosen to deliver energy into the rock while minimizing the chance of striking crusher shells, grizzly bars, or supporting steel.
Electric-hydraulic power unit
Power for the breaker is delivered by an electric-hydraulic module, typically including motor, pumps, reservoir, filtration, and cooling.
This arrangement offers reliable, low-operating-cost power compared with mobile excavator-mounted breakers and is optimized for fixed, high-duty breaking tasks.
Control and safety integration
Operators control the rockbreaker from a protected station, with simple, robust controls for starting, stopping, and adjusting blow frequency as required.
Interlocks, permissives, and emergency stop circuits can be integrated with crusher and feeder controls so that breaking work fits safely into existing operating procedures.
The Fixed Rockbreaker often works together with a YZH fixed boom system (such as WHC or WHA series), forming a complete fixed rockbreaker boom system for secondary breaking and oversize control.
YZH Fixed Rockbreakers are used wherever fixed, repeatable oversize reduction is required:
Primary jaw and gyratory crushers processing run-of-mine ore in metal, aggregate, and industrial minerals operations.
Grizzly screens and fixed hoppers where long or flat rocks regularly span across openings and require direct impact breaking.
Chutes, ore passes, and transfer points in mines and plants that occasionally plug with large rock or slag and cannot be safely cleared with mobile machines alone.
In each case, the fixed rockbreaker station is located and oriented so that one installation can handle all expected oversize and hang-up positions at that point in the circuit.
While this page describes the “YZH Fixed Rockbreaker” as a product, the actual solution is engineered to each site:
YZH’s rockbreaker team reviews plant drawings, crusher/grizzly geometry, feed characteristics, and production targets to define breaker size, mounting height, and working angles.
The fixed rockbreaker is then combined with an appropriate boom or support arrangement from YZH’s fixed boom system portfolio to ensure complete coverage of the problem zone.
Power supply, control philosophy, and structural loads are specified in detail so the station can be installed and commissioned with minimal disruption to existing operations.
Optional features—such as advanced remote controls, monitoring of breaker performance, or integration with camera systems—can be added for operations moving toward higher automation and remote operation.
Developed as part of a comprehensive fixed rockbreaker boom and system portfolio, with proven performance in mines, quarries, and cement plants worldwide.
Heavy-duty designs with reinforced structures, high-quality hydraulic components, and electric power units provide long service life under severe, continuous-duty conditions.
A single engineering partner for breaker, boom, power, and controls simplifies planning, ensures that all elements work together, and makes future upgrades and service more straightforward.
If oversized rock and manual breaking are still dictating when your primary crusher or grizzly runs, a YZH Fixed Rockbreaker station can turn that critical point into a controlled, engineered impact zone.
Share your crusher or grizzly layout, typical oversize profile, and capacity goals, and YZH will design a fixed rockbreaker configuration—combined with the right boom system where needed—that delivers reliable, safe oversize control for your plant.
