Stationary rockbreaker boom system is an advanced hydraulic boom assembly designed to eliminate downtime and enhance the safety and productivity of primary crushing operations. Specifically engineered for use over jaw crushers, grizzly screens, gyratory crushers, and material chutes, stationary rockbreaker boom system is essential for breaking oversize rocks, raking bridged material, and preventing blockages.

Whether you're operating in open-pit mines, hard rock quarries, aggregate plants, or underground crushing environments, this heavy-duty boom system offers consistent performance in the most challenging applications.

Core Functions of Stationary Rockbreaker Boom System:

Blockage Clearance: Rapidly breaks oversize rock material clogging crusher inlets.

Bridged Material Raking: Rakes down bridged material over grizzly bars into the crusher feed zone.

Operational Efficiency: Eliminates costly downtime by automating the rockbreaking process.

Operator Safety: Removes the need for manual intervention using hydraulic or remote-controlled tools.

Typical Applications of Stationary Rockbreaker Boom System:

1. Jaw crushers (primary)

Application Role:

Installed above or beside the feed opening of primary jaw crushers, stationary rockbreaker boom system is used to break oversized boulders before they enter the crushing chamber. It also helps dislodge rocks that get stuck between the moving and fixed jaw plates.

Purpose & Benefits:

Prevents oversized rocks from damaging crusher jaws

Reduces downtime caused by feed blockage

Eliminates the need for dangerous manual clearing

Ensures smooth and continuous operation

2. Impact crushers

Application Role:

In impact crusher setups, stationary rockbreaker boom system is positioned at the hopper inlet or feed chute. It breaks large feed material and prevents clogging or bridging that may occur due to inconsistent feed size or sticky materials.

Purpose & Benefits:

Breaks irregularly shaped rocks before entering the crushing rotor

Prevents feed chute blockages

Reduces impact plate wear from oversize rocks

Maintains production rate by ensuring constant feed flow

3. Gyratory crushers

Application Role:

Typically installed above the spider or feed opening, stationary rockbreaker boom system is used to break large rocks suspended in the top of the gyratory crusher or stuck in the feed hopper. These are often heavy-duty, long-reach booms with 170° rotation.

Purpose & Benefits:

Breaks boulders before they enter the crushing zone

Clears bridging and blockages at the hopper throat

Supports high-capacity, continuous duty applications

Enhances safety by replacing manual clearing with remote operation

4. Grizzly feeders (screens)

Application Role:

Mounted over the grizzly bars, stationary rockbreaker boom system rakes or breaks bridged material that gets stuck between the grizzly rails. It ensures that finer material falls through and oversize material is properly handled.

Purpose & Benefits:

Removes bridged rocks that obstruct the grizzly deck

Allows proper separation of fines and oversize

Prevents bottlenecks in the crushing process

Improves overall plant efficiency and feed uniformity

5. Hopper entry points

Application Role:

Boom system installed above or beside hopper inlets helps manage blockages caused by material arching or bridging, especially when large rocks are dumped from haul trucks or loaders. The boom dislodges hung-up material for smooth flow.

Purpose & Benefits:

Prevents material build-up at hopper mouths

Reduces dump truck wait times by ensuring fast unloading

Improves material flow consistency

Avoids spills or overflow caused by clogged hoppers

6. Stationary and mobile crushing plants

Application Role:

Stationary rockbreaker boom system is integrated into fixed plant layouts to provide permanent rockbreaking capability at key flow points like crushers, feeders, or transfer chutes. They are engineered for long-term, high-duty operation.

Purpose & Benefits:

Provides on-demand breaking in any critical area

Increases plant uptime by reducing manual interventions

Enhances safety by automating hazardous tasks

Fully integrated into plant power and control systems

7. Mobile Crushing Plants

Application Role:

Specialized compact boom systems are mounted directly onto mobile crushers or trailers. These booms help break oversized rocks in portable setups where space and height are limited.

Purpose & Benefits:

Designed for space-restricted environments

Maintains crusher throughput in mobile setups

Facilitates relocation and deployment at multiple sites

Enhances the flexibility and productivity of mobile crushers

Mounting Configuration Examples

1. Stationary Pedestal Mount Next to Jaw Crusher – Fixed to ground, feeds jaw directly.

This is the most common configuration. The boom system is permanently bolted to a concrete or steel base next to the jaw crusher inlet. It provides direct coverage for the feed opening, allowing it to break oversized rocks before they enter the crushing chamber.

2. Bridge Mount Over Hopper – Ideal for grizzly and dump chute coverage.

A structural steel frame is constructed across the hopper or feed chute, and the boom is mounted directly onto the bridge. This setup is ideal when material enters from the top via truck dumping or conveyor, and full horizontal coverage is required.

3. Mobile Crawler or Trolley Mount – For temporary or multi-location usage.

Designed for jobs where relocation is necessary, this configuration features the boom system on a mobile platform such as a rail trolley, wheeled cart, or crawler chassis. It’s ideal for multi-location sites or short-term jobs.

4. Hydraulic Lift Platform Mount – For adjustable height access.

The rockbreaker is mounted on a vertical lift platform, which can be raised or lowered as needed. This allows the boom to operate at different elevations depending on crusher height or material pile levels.

5. Round Shock-Absorbing Pedestal – Reduces vibration and protects structure.

This base is equipped with vibration-dampening elastomers or springs, designed to reduce structural stress and absorb shock loads during heavy breaking. It is typically used with larger booms in high-impact environments.
