Product Description
In underground and surface mines, oversize rock and hang‑ups at crushers, ore passes and grizzlies interrupt hoisting and hauling, creating long queues and safety hazards. YZH mining rock breaker boom systems are installed at these points as dedicated breaking stations: the boom positions the breaker where rock accumulates, so material can be reduced and moved without relocating mobile equipment or bringing in explosives.
Rather than treating oversize as an exceptional event, mine operators use the boom system as part of normal production, clearing trouble spots quickly and keeping ore moving toward the plant.
Secondary breaking of oversize too big for the crusher
Run-of-mine ore often contains boulders or very hard zones that exceed crusher opening size or are too tough to break in one pass.
The boom-mounted breaker performs controlled secondary breaking at the crusher mouth or ore pass lip, sizing rock so the crusher and downstream equipment can handle it efficiently.
Blockages in ore passes, drawpoints and grizzlies
In underground mines, ore passes and drawpoints can choke with wedges or arching rock; surface grizzlies see similar bridging.
A rock breaker boom station at these locations lets operators break and dislodge hang‑ups from a safe location, restoring flow without sending crews under unstable rock.
Safety exposure from manual and mobile methods
Using hand tools, small breakers or loaders in tight headings and at ore pass mouths exposes workers to falling rock and unstable walls.
With YZH’s pedestal boom systems, the breaker is fixed to a base and controlled remotely, dramatically reducing exposure to falling rocks and unstable slopes in the mine.
Mining applications typically use the same four main components described for pedestal breaker boom systems, tuned for mine conditions:
Pedestal boom
A heavy-duty boom fixed to a pedestal base, with geometry tailored to reach crusher mouths, ore pass openings or grizzly surfaces within confined spaces.
Round pedestals, shock-absorbing mounts and robust weldments help the boom withstand continuous impact and vibration in both surface and underground headings.
Hydraulic breaker (rock hammer)
A breaker suited to mine rock hardness and typical boulder size is mounted at the boom tip, providing impact for secondary breaking and blockage clearing.
Models like YZH750–YZH850 are common on compact pedestal systems, while larger units are used on long-reach booms for big crushers or high ore pass lips.
Hydraulic power unit
Electric power packs sized 18–30 kW and above drive the boom and breaker, with oil filtration and cooling chosen for dusty, high-duty mining environments.
Power units can be located away from the breaking point to simplify service and protect sensitive components from blast and dust.
Control system
Control options range from local panels in protected niches to remote consoles or radio controls in surface or underground control rooms.
This allows operators to work from safe, ergonomic positions while still placing the breaker accurately on oversize or hang‑ups.
YZH rock breaker boom systems applied for mining are suitable for:
Underground jaw or gyratory crushers at shaft bottoms or main haulage levels, where ore size must be controlled before hoisting or conveying.
Ore passes, drawpoints and grizzly stations in block cave, sublevel stoping and other underground methods where rock frequently bridges and needs breaking.
Surface primary crushers and stockpile feed points in open‑pit mines where oversize and tramp material regularly disrupt crushing circuits.
Systems can be supplied as fixed or semi‑stationary, with booms and pedestals configured to match mine headings, access constraints and long-term infrastructure plans.
Although marketed under a common “rock breaker boom system applied for mining” name, each project is engineered for the mine’s layout and method:
YZH’s team reviews mine drawings, crusher and ore pass locations, working headings and rock properties to propose boom models, breaker sizes and pedestal positions.
For underground applications, boom envelopes and pedestal sizes are tuned to fit within drift dimensions while still reaching all expected hang‑up points.
Systems are delivered as turn‑key packages—boom, breaker, power unit and controls—ready for installation and commissioning on site.
If oversize rock, ore pass blockages or unsafe manual breaking are still limiting your mining production, a YZH rock breaker boom system can transform those trouble points into engineered, remote‑operated breaking stations.
Share your mine layout, crusher and ore pass locations, and typical rock conditions, and YZH will configure a rock breaker boom system tailored to your mining operation’s safety and productivity targets.
