Product Description
Gyratory crushers sit at the center of many high‑capacity plants, but their tall, deep throats and large rock boxes make oversize and bridging difficult to clear with generic tools. A pedestal rock breaker boom with adjustable configuration is designed so reach, articulation and mounting position can be tuned to each gyratory’s spider and feed arrangement, allowing the breaker to work where rocks actually hang up.
This flexibility means the same boom platform can be adapted across different gyratory models or used when plant layouts change, without sacrificing coverage or safety.
Oversize and hang‑ups deep in the gyratory throat
Large boulders and slabby rocks can become wedged on the rim of the rock box, along the spider region or on the concaves, starving the crusher and stressing the drive.
By positioning the breaker in line with the upper support (spider) and sizing the boom envelope correctly, the system can break these pieces and push fragments into the crushing zone without stopping the plant for manual clearing.
Changing layouts and different gyratory sizes
Mines and quarries often change feed arrangements, chutes or liners, which can shift where hang‑ups occur and alter access to the crusher throat.
Adjustable configuration lets YZH adapt boom length, pedestal location, mounting style and breaker choice so the rockbreaker remains effective even as the plant evolves.
Safety and maintenance risks from improvised clearing
Without a properly matched boom, crews may resort to partial entry or rely heavily on mobile equipment working close to high walls and open throats.
A dedicated pedestal boom with correct geometry and control keeps operators at a safe distance, with the breaker doing the high‑risk work inside the gyratory.
YZH follows the standard four‑component pedestal rockbreaker architecture, adding adjustability around gyratory needs:
Pedestal base and boom
A round or square pedestal is anchored to concrete or structural steel near the crusher, with shock‑absorbing pedestal mounting options available for high‑impact duties.
Boom reach, section size and joint geometry are selected so the breaker can sweep across the full rock box and into the mineral stream while avoiding contact with the spider and liners.
Hydraulic breaker (hammer)
Suitable hydraulic hammers in the 135–140 class and above are available (depending on boom size) for stationary crushers, grizzlies and gyratory applications, giving enough energy for hard ore.
Breaker selection is part of the adjustable configuration—energy class, tool type and mounting bracket are matched to rock hardness, lump size and gyratory duty.
Hydraulic power unit
An electric hydraulic station supplies pressurized oil to the boom cylinders and breaker, with cooling and filtration specified for continuous duty in mining and quarrying environments.
Location and enclosure style of the power unit can be adapted to the crusher station layout, making service access easier and protecting components from dust and vibration.
Control system
Systems can be operated from local consoles or via remote controls, with options ranging from simple non‑programmable logic to smarter controls that integrate with crusher interlocks.
Adjustable control configurations allow operators to fine‑tune boom speed, damping and hammer functions for more precise work inside the gyratory rock box.
According to gyratory rockbreaker application guidance, the boom should be mounted in line with the upper support (spider) for superior maneuverability in the throat. YZH pedestal rock breaker booms with adjustable configuration are thus suited to:
Primary gyratory crushers in high‑tonnage mines and quarries where deep cavities and large boulders create frequent hang‑ups.
Gyratory feed rock boxes where oversize tends to accumulate on rims or shelves and must be broken down before entering the crushing chamber.
Combined gyratory and grizzly stations where a single boom must serve both the rock box and a nearby scalping or protection grizzly.
Even though this product is described as a “pedestal rock breaker boom with adjustable configuration for gyratory crusher,” the final solution is engineered case by case:
YZH engineers review gyratory dimensions, spider design, rock box shape, feed arrangement and expected hang‑up zones to define boom reach, pedestal position and swing range.
3D and 2D layout checks ensure the breaker can reach all critical areas in the throat and rock box without fouling structural members or liners.
Breaker size, power unit capacity and control options are then selected to deliver the required breaking performance under the site’s duty cycle and environmental conditions.
If your gyratory crusher is losing time to deep throat hang‑ups or relies on improvised clearing methods, a YZH pedestal rock breaker boom with adjustable configuration can give you a tailored, safe oversize‑control station for that crusher.
Share your gyratory crusher drawings, rock characteristics and production targets, and YZH will configure boom geometry, breaker size and pedestal layout to match your exact application.
