What is a Rock Breaker Machine and How Does It Work?

When construction jobs require rock or concrete demolition, rock crushers are indispensable. Aptly named, as they are designed and built for the sole purpose of breaking rock into manageable sizes that can then be moved safely and efficiently.

These powerful machines are a common sight on construction sites where substantial demolition work is required. In this blog post we will find out all about the mighty rock crushers.

Understanding the Rock Breaker

A hydraulic breaker, also known as a hydraulic hammer, is a piece of construction equipment attached to excavators, backhoes, skid steers and mini excavators. It consists of an arm, which is the extension, and at the end of which is the hammer, which applies repetitive force to break rock/concrete into smaller and more manageable pieces.

Components and Types of Rock Breakers

A typical rock breaker consists of two main parts: a hammer (used to break the hard materials) and an arm to which the hammer is attached. Breakers can vary in size and design. Depending on the application, they can range from small, hand-held units to large, powerful machines mounted on construction vehicles.

Impact Rate:

Typically between 500 and 1,500 strokes per minute.

Tool Diameter:

Typically between 45 and 175 mm, depending on the size of the job.

Carrier Weight:

Matched to the weight of the excavator or backhoe, from 1 tonne to over 50 tonnes, ensuring stability and efficiency.

Hydraulic Flow:

Required flow rates can vary from 20 to 150 litres per minute, depending on the hydraulic capabilities of the machine.

The operational mechanics of how rockbreakers workx

The operation of a Rock Breaker is relatively simple and highly efficient. It uses a high-pressure hydraulic system that supplies hydraulic fluid to the breaker's cylinder. This fluid applies pressure to a piston, which in turn transfers the force to a tool shaft, usually a steel chisel. The repeated hammering of the chisel into the rock or concrete breaks it up.

Rock Breaker Machine Efficiency

Efficiency in rock breaking is achieved by the powerful, concentrated force that the Rock Breaker applies to the material. Unlike traditional methods of rock breaking, which require multiple workers and a variety of construction tools, a Rock Breaker machine delivers fast, powerful blows that break rock and concrete efficiently and at a much lower cost. The efficiency parameters of a Rock Breaker include

Energy output: The energy delivered per blow, which has a direct impact on the breaking capacity.
Operating weight: Balancing the weight of the machine with its output force to optimise energy transfer.

Rock Breaker Applications in Construction

The versatility of breakers allows them to be used in a variety of construction and demolition applications. These include:

Excavation of foundations

Trenching in rocky ground

Tunneling through rock

Demolition of concrete structures

Secondary breaking in quarries

Rock Crusher Maintenance

Proper maintenance is essential to ensure the longevity and effectiveness of a rock breaker. Routine inspections for wear and tear, regular greasing to keep parts lubricated and ensuring hydraulic systems are free of contaminants are all part of the upkeep for this robust piece of construction equipment.

Conclusion

A Rock Breaker is an indispensable part of the construction industry's machine arsenal. It is a testament to advances in construction vehicle and equipment technology, providing a practical and cost-effective solution to rock and concrete removal. When properly maintained and operated, rock breakers can significantly increase productivity, ensuring that construction projects stay on track and within budget.

If you're in the market for a rock breaker, understanding its operation and maintenance will help you make an informed decision and ensure you have the right equipment for your construction needs.
