Application and Selection Guide of Hydraulic Breaker in Rock Crushing

How does a hydraulic breaker work in rock crushing?

A hydraulic breaker is a powerful impact tool usually mounted on an excavator to break hard rocks and concrete structures. Its working principle is to drive the piston through a hydraulic system to generate high-frequency impact force to break the rock into smaller fragments for subsequent processing and transportation.

What factors should be considered when selecting a hydraulic breaker?

When selecting a hydraulic breaker, the following factors should be considered:

Carrier compatibility: Ensure the compatibility of the breaker with the excavator or other carrying equipment, including hydraulic flow, pressure, and mounting system.
Application type: Select the appropriate breaker type and size according to the specific crushing task. For example, a small breaker is suitable for interior decoration and small-scale concrete crushing, while a large breaker is suitable for mining and large demolition projects.
Operating weight: Select an appropriate operating weight to ensure the stability of the equipment and the safety of operation.
Maintenance requirements: Consider the difficulty of maintaining the breaker, and select a model that is easy to maintain and has readily available spare parts to reduce downtime and maintenance costs.

What are the common types of hydraulic breakers?

Hydraulic breakers are mainly divided into the following three categories:

Small breakers: suitable for interior decoration, small-scale concrete crushing and excavation operations.
Medium breakers: widely used in large concrete crushing, large rock crushing and utility projects.
Large breakers: used in mining, demolition and large excavation projects, providing higher impact and efficiency.

What are the main application areas of hydraulic breakers?

Hydraulic breakers are widely used in the following fields:

Construction and demolition: used to crush concrete, steel bars and other materials, demolish buildings, roads and bridges.
Mining: In mining operations, help to efficiently crush and decompose hard rocks, reduce reliance on blasting, and ensure safety.
Quarrying: In quarries, large rock blocks are broken into manageable sizes for subsequent processing or transportation.
Utility projects: used in projects such as excavation, road repair or pipeline installation, to handle hard rock and soil layers.

What are the safety measures and best practices when operating hydraulic breakers?

When operating a hydraulic breaker, the following safety measures and best practices should be followed:

Wear appropriate personal protective equipment: including hard hats, safety glasses, ear plugs and steel-toed boots to protect yourself from splash, noise and other potential hazards.
Inspect the equipment regularly: Before each use, check all parts of the breaker to ensure that there is no damage or wear and all connections are tight.
Follow the manufacturer's operating instructions: Familiarize yourself with the characteristics and control methods of the breaker used to ensure safe and efficient operation.
Establish a safe work area: Clear the work area to ensure that there are no people or obstacles, and use warning tape or barriers to mark the work area to prevent unauthorized personnel from entering.
Maintain a stable operating posture: Ensure that the equipment is on a stable ground and use outriggers or stabilizers when necessary to prevent the equipment from overturning.
Avoid excessive force: Each breaker has its capacity and limitations. Avoid overloading to prevent equipment failure and potential accidents.
Keep a safe distance: During operation, ensure that you and other personnel are away from the crushing area to avoid being hit by splashing objects.

By following the above safety measures and best practices, you can maximize the efficiency of the hydraulic breaker and ensure the safety of the operator.

What are the recommendations for the maintenance and care of the hydraulic breaker?

To ensure the long-term and efficient operation of the hydraulic breaker, the following maintenance and care should be performed regularly:

Regular lubrication: Ensure that all moving parts of the breaker are fully lubricated to reduce wear and extend service life.

Check tools and accessories: Regularly check the tools (such as chisels, impactors) and other accessories of the breaker to ensure that they are not worn or damaged, and replace them when necessary.
Clean equipment: Keep the breaker clean to prevent dust and debris from accumulating and affecting the performance of the equipment.
Check the hydraulic system: Regularly check the pressure and flow of the hydraulic system to ensure that it is within the normal range to prevent failures caused by hydraulic problems.
Follow the maintenance plan: Refer to the maintenance manual provided by the manufacturer and perform maintenance and inspections at the recommended intervals.

Through regular maintenance and care, you can ensure the optimal performance of the hydraulic breaker, reduce failures and downtime, and improve work efficiency.

What are the common faults of hydraulic breakers and how to troubleshoot them?

When using a hydraulic breaker, you may encounter the following common faults and their troubleshooting methods:

Insufficient impact force: This may be caused by insufficient hydraulic system pressure, tool wear or poor lubrication. Check the hydraulic system to ensure normal pressure; check the tool and replace it if necessary; ensure adequate lubrication.

Overheating: This may be caused by long-term continuous operation or hydraulic system failure. Ensure intermittent operation to avoid overuse; check the hydraulic system to ensure normal operation.

Abnormal noise or vibration: This may be caused by wear or damage to internal components. Stop using the equipment, check the internal components, and repair or replace them if necessary.

Hydraulic oil leakage: This may be caused by aging or damage to the seal. Check all connections and seals and replace them in time if any problems are found.

When encountering the above faults, timely inspection and repair should be carried out to ensure the normal operation of the hydraulic breaker.

By understanding the application, selection guide, safe operation, maintenance and troubleshooting methods of hydraulic breakers, users can better utilize this equipment, improve work efficiency and ensure safety.
