Product Description
According to YZH product information, these systems are installed on mobile, portable and stationary crushing plants in mines, quarries and industrial sites worldwide. Typical mounting points include primary crusher mouths, grizzly feeders, rockboxes and ore‑pass openings where there is frequent oversize or bridging.
By placing the rockbreaker exactly where problems occur, plants turn reactive, manual clearing into a controlled, mechanized process that can be performed quickly and repeatedly.
Oversize and crusher blockages
Large or irregular rocks often wedge at the crusher inlet or inside the chamber, forcing shutdowns and risky attempts to dislodge them manually or with mobile equipment.
A rockbreaker system positions the hammer over these obstructions so operators can break and push material into the crusher, reducing downtime and mechanical stress.
Bridging on grizzlies and in rockboxes
Grizzlies, ore passes and rockboxes can bridge when slabby rocks sit across openings, cutting off feed to downstream equipment.
The boom allows operators to break, rake and pull down material from a safe distance, restoring flow through bars, chutes or pockets.
Unsafe manual clearing and slinging oversize
Before dedicated rockbreaker systems, workers often had to stand near open crushers or swing oversize out of rockboxes, which exposed them to falling material and flying debris.
With YZH rockbreaker systems, operators are placed a safe distance away and work via controls or remote consoles, eliminating these dangerous procedures.
YZH and pedestal‑boom documentation describe a complete rockbreaker system as consisting of four core elements:
Pedestal boom
A heavy‑duty articulated boom is mounted on a pedestal or structural frame near the crusher, grizzly or ore pass, optimized for stress distribution and long service life.
Hydraulic breaker (rock hammer)
A hydraulic breaker sized for the application (light, medium or heavy duty) is installed at the boom tip to perform primary and secondary breaking.
Hydraulic power unit
An electric‑hydraulic power pack provides oil flow and pressure to the boom and breaker, with filtration and cooling selected for continuous mining and quarry operation.
Control system
Systems can use local joystick controls, electric‑hydraulic controls, radio remote controls or camera‑assisted long‑distance operation, depending on site needs.
These components are matched so boom reach, breaker energy and hydraulic capacity fit the specific station’s geometry and duty.
Available information on YZH and comparable stationary rockbreakers highlights common design ranges:
Boom reach options from roughly 3,000 mm up to around 10,000 mm to suit small to very large crusher and grizzly layouts.
Working rotation typically about 170° on swing‑post pedestals; some systems use turntable or similar designs for greater swing where required.
Breaker capacity matched to rock hardness and lump size, with tool diameters and energy classes selected per application.
Control options from simple local controls to smart, programmable systems integrated with plant PLCs.
These features allow each rockbreaker system to provide full coverage of the area where material needs breaking, raking or clearing.
From YZH’s rockbreaker and fixed boom descriptions, key benefits include:
Improved safety: Operators are removed from open crushers and flying debris, working instead from a safe control location.
Reduced downtime: Oversize and blockages are resolved quickly, keeping crushers and grizzlies operating near capacity.
Long service life: Systems are built with high‑tensile steel, oversized pins and heavy‑duty bushings to handle continuous, severe‑duty work.
Custom engineering support: YZH provides site‑specific assessments, layout drawings and boom selection to ensure correct positioning and coverage.
If oversize, crusher jams or grizzly blockages are limiting your production or putting workers at risk, a YZH rockbreaker system can turn those points into engineered rockbreaking stations.
Share your plant layout, crusher or grizzly dimensions, ore characteristics and capacity targets, and YZH will prepare a rockbreaker system proposal tailored to your site.
