Product Description
Mining plants often lose production when run‑of‑mine ore bridges at crusher inlets, sits on grizzly bars or wedges in chutes, forcing crews to intervene manually. A YZH stationary pedestal rockbreaker system is positioned at these bottlenecks so the boom can reach into the feed zone and apply breaker energy exactly where oversize or hang‑ups occur, restoring flow quickly.
Because the rockbreaker is a fixed part of the plant structure, it works as a planned step in the ore handling process rather than as an emergency measure.
Oversize and bridging at crushers and grizzlies
Large boulders or slabby rocks can block jaw and gyratory crushers or form arches across grizzly bars, stopping the line.
The pedestal boom positions the breaker above these pieces so operators can fragment and rake material until it passes into the crusher or through the grizzly.
Unsafe manual clearing and secondary blasting
Traditional methods—hand barring, small tools or explosives—expose workers to falling rock, fumes and unstable piles.
With a stationary pedestal rockbreaker, breaking is performed from a safe control station using joysticks or remotes, eliminating the need to stand near open crushers or ore passes.
Downtime and stress on mining equipment
Frequent stoppages increase wear on crushers, feeders and conveyors and disrupt production plans.
By dealing with oversize immediately and consistently, the system smooths ore flow, raises effective tons per hour and reduces mechanical stress on critical equipment.
YZH stationary pedestal rockbreaker systems follow the four‑component architecture described for its stationary rockbreakers:
Pedestal boom and base
A heavy-duty boom is mounted on a fixed pedestal anchored to concrete or steel foundations beside the crusher, grizzly or chute.
B‑series and similar booms are built from high-strength steel with reinforced welds and wear‑resistant bushings, designed for 170° working rotation in many models to cover broad areas.
Hydraulic breaker (hammer)
A hydraulic hammer matched to ore hardness and maximum oversize weight delivers the blows required for secondary breaking and hang‑up removal.
YZH stationary systems typically support breakers up to about 2,000 kg, sufficient for demanding mining applications at primary stations.
Hydraulic power unit
Electric motors around 37–55 kW (model‑dependent) drive pumps supplying up to roughly 20–25 MPa pressure and 90–130 L/min oil flow for boom and breaker operation.
Integrated filtration and cooling systems keep oil clean and at the right temperature for continuous mining duty.
Control and safety system
Proportional joystick controls and optional remote systems give operators precise, smooth boom and hammer movement.
Safety features such as emergency stops, pressure relief valves and interlock options support safe integration with plant control and lockout procedures.
YZH stationary pedestal rockbreaker systems are used across the mining industry wherever fixed oversize control is required:
Primary and secondary crushers in open‑pit and underground mines.
Grizzly feeders and coarse screens ahead of crushers, where rocks must be reduced before further processing.
Ore chutes, transfer points and surge pockets where occasional boulders or hang‑ups threaten continuous operation.
Boom reach for these systems commonly spans about 3,000–10,000 mm, allowing selection for small to very large mining stations.
Although presented as a “stationary pedestal rockbreaker system for mining industry,” each installation is engineered to the mine’s layout and duty:
Engineers study crusher or grizzly drawings, ore characteristics and throughput targets to choose boom size, breaker capacity and pedestal location.
Coverage and rotation are checked against the actual feed and hang‑up areas so that all critical points fall within the boom’s working envelope.
Structural, hydraulic and electrical interfaces are defined for new or existing plants, enabling straightforward installation and commissioning.
If oversize, grizzly hang‑ups or chute blockages are restricting your mining plant’s output, a YZH stationary pedestal rockbreaker system can convert those trouble spots into engineered oversize‑control stations.
Share your crusher or grizzly layout, ore properties and production goals, and YZH will configure a pedestal rockbreaker solution tailored to your mining operation.
