Product Description
In a mine development or expansion project, the primary crusher station and ore transfer points often become bottlenecks when oversize or bridging forces crews to intervene manually. A YZH stationary rockbreaker system is designed into the layout as part of the primary station: mounted on a fixed pedestal, the boom reaches into the crusher mouth, across the grizzly or into the chute, breaking and raking rock so ore flow stays continuous.
By integrating the rockbreaker at the project stage rather than as an afterthought, mines can size structures, foundations and power supply correctly, reducing retrofit costs and shortening commissioning times.
Oversize and blockages at primary crushers and grizzlies
Run-of-mine ore frequently contains boulders or slabby rock that cannot pass the crusher opening or grizzly bars, causing repeated stoppages.
The stationary rockbreaker system breaks these pieces before or as they enter the crusher feed area and rakes fragments into the chamber, preventing jams and protecting the crusher from overload.
Unsafe, labour-intensive clearing and secondary blasting
Without a dedicated rockbreaker, mining projects rely on manual barring, mobile equipment or secondary blasting, all of which increase risk and delay.
A pedestal boom system mechanizes these tasks, allowing operators to work from a control station or remote panel while the breaker clears blockages from a safe distance.
Unplanned downtime and reduced project economics
Repeated shutdowns at the primary station undermine production forecasts and raise unit costs for new or expanded mines.
By stabilizing throughput and reducing unplanned interventions, the stationary rockbreaker improves adherence to mining project schedules and cost targets.
Descriptions of YZH B‑series and static rockbreaker systems show the typical building blocks and performance ranges:
Pedestal boom and structural base
A rigid pedestal is fixed to reinforced foundations or supporting steel near the crusher or grizzly, carrying a boom whose reach is selected for the site geometry.
Typical boom reach ranges from about 3,000 mm up to around 10,000 mm for larger systems, covering small to large primary stations.
Hydraulic breaker (hammer)
A hydraulic hammer matched to rock hardness and maximum oversize weight is mounted at the boom tip, providing focused impact for secondary breaking and blockage removal.
YZH B‑series and static rockbreakers are capable of working with breakers up to roughly 2,000 kg class, suitable for demanding mining applications.
Rotation and working envelope
Many stationary systems offer around 170° hydraulic rotation, giving a wide working envelope so operators can cover the entire crusher mouth, grizzly width and adjacent rockbox from one pedestal.
Hydraulic power unit and controls
Electric motors in the 37–55 kW range (model‑dependent) drive hydraulic pumps supplying 20–25 MPa pressure and flows around 90–130 L/min to the boom and breaker.
Systems can be controlled manually, via simple on‑board controls, or remotely, enhancing safety by keeping operators out of high‑risk areas.
According to YZH’s mining‑oriented product descriptions, these systems are suited to multiple points in a mine flowsheet:
Primary jaw or gyratory crushers in open-pit and underground mines, preventing blockage and improving crusher utilization.
Grizzly feeders and heavy‑duty screens that separate oversize before crushing, where bridging and build‑ups are common.
Ore chutes or transfer points feeding conveyors or shaft systems, where occasional large blocks can halt material flow.
In each case, a stationary rockbreaker becomes a permanent oversize‑management station built into the mine’s infrastructure rather than a mobile, temporary solution.
Even though the product is presented as “YZH Stationary Rockbreaker System for Mining Project,” each installation is customized:
Engineers use crusher and grizzly drawings, ore characteristics and capacity targets to select boom length, breaker size and rotation range appropriate for the project.
Structural and power requirements are specified so civil, mechanical and electrical teams can design foundations, supports and power feeds as part of the overall project.
Multiple stations (for example, at the primary crusher and at a secondary grizzly) can be standardized on the same platform to simplify spares and training.
If your mining project’s primary station design still relies on manual clearing or mobile equipment for oversize, integrating a YZH stationary rockbreaker system can turn that critical area into a controlled, remote‑operated oversize management station.
Provide your crusher or grizzly layout, expected ore size distribution and production targets, and YZH will propose a stationary rockbreaker configuration engineered to support your mining project’s safety and throughput goals.
