The Best Use Purpose of a Rock Breaker
YuchaiHI Product Page
Rock breakers are used in various industries, and although their name is self-explanatory, they actually have a wide range of use cases. For example, in landscaping, they can be used to crush larger rocks for easier transportation. In mining, a rock breaker is used to break down materials that don&#;t fit in a crusher. These are just a couple of the uses, and there are many more.
Let&#;s take a more detailed look at rock breakers and some of their extremely important uses.
What is a rock breaker?
In very simple terms, a rock breaker is a piece of mining equipment that breaks up rocks. It&#;s used in mining, landscaping and construction. While there are dedicated machines used for breaking rocks in some circumstances, the most common type is an excavator attachment that attaches to the front of your machine.
The attachment itself works essentially like a piston, with pressure being applied through the excavator&#;s arm. Basically, it hammers the rocks or hard terrain to break it up into smaller, more manageable pieces. Think of it like a huge jackhammer attached to an excavator.
The idea is to break up the ground or rocks so that the debris can be removed. As we&#;ll touch on, there are many different specific uses for a rock breaker, but this is the main function.
Are there different size rock breakers?
The size of the rock breaker you choose depends on the scale of the job. The bigger rocks you need to break, the bigger your rock breaker needs to be. Fortunately, there are all types of rock breakers out there in various sizes. The other determining factor is the size of your excavator because you&#;ll need an attachment that fits.
Here at Earthmoving Equipment Australia, we offer rock breakers that are suitable for 1-tonne diggers up to 55-tonne excavators. So, there&#;s a lot of variety out there, and if you&#;re unsure of the rock breaker size you need, it always pays to ask your supplier.
Breaking rock for landscaping
Rock breakers are a popular tool for landscaping. In fact, there are multiple ways they can be used in this setting. Firstly, the rock breaker can crush rock into smaller pieces, which makes it easier to use as a base for patios and pathways. But in addition, it can be useful for breaking down larger rocks that can&#;t be moved by hand. You may want to use large rocks for a garden wall, for example. Using a rock breaker, you can split those rocks to be more easily moved around the work site and utilised accordingly.
Breaking concrete
We&#;ve probably all seen a jackhammer in use, breaking up small areas of concrete. But what if you have a larger area of concrete that needs to be removed? Rather than spending hours slaving away with a jackhammer, if you&#;ve got an excavator available, using a rock breaker attachment is a much more time-efficient way to do the work.
A rock breaker can crush concrete into smaller debris, making it easy to remove from the site. By the same token, if you want the concrete crushed small enough to be re-used elsewhere in a project, you can do that with a rock breaker, too.
Rock breakers in the mining industry
In the mining industry, rock breakers are commonly used to break up large rocks. This is because a lot of mining operations also use rock crushers, but some rocks are too large to fit. So, breaking them up makes the process a whole lot easier.
There are multiple situations where rocks may need to be broken up around a mine site. Usually, this is for transportation purposes. Even excavators can&#;t handle rocks of a certain size, so a rock breaker is used to make them smaller prior to removal.
Clearing rocky terrain
Rock breakers can also be used in the construction industry, where rocky terrain needs to be essentially removed. It may be that the construction of a building or even a road is impeded by rocky surfaces. A rock breaker can be used to break up the ground, making it easier for other equipment to come in and remove the debris before preparing the site for construction.

What is Hydraulic Breaker and How Does It Work? - JIANGTU

Hydraulic Breaker
A Hydraulic Breaker, also known as a percussion hammer, is a heavy mechanical device used to demolish concrete, asphalt, or stone materials. Hydraulic breakers are commonly seen in road construction and are preferred due to their high performance.
This article gathers information about the best use cases, how they work, and how they are operated. Let&#;s take a look at the details!
What are the General Characteristics of a Hydraulic Breaker?
In preparation for construction activities, there are several phases of work, including demolition, site preparation, road surface excavation, and public works. To create a modern cityscape, it is sometimes necessary to demolish neighborhoods, often break up sidewalks when opening utility trenches, extend and maintain the network, and remove obstacles in the way of an excavator. Manual demolition hammers that used compressed air for demolition work no longer met growing economic and technical demands.
These tools were sometimes very noisy, required a lot of physical effort from the workers, and we&#;re far behind other technologies in the chain. Therefore, it has become necessary to develop a range of working tools for hydraulic excavators in a direction aimed at specialized tasks.
Innovation was triggered by a combination of factors:
Some of the assemblies developed are suitable to replace special machines, others decrease the need for manual labor or increase productivity. Assemblies that replace specialized machinery include pile driving equipment, plow lowering and pulling devices, deep compaction assemblies.
JIANGTU has been developed to meet the high standards of the current market. The demand for high durability and low maintenance costs on hydraulic equipment are combined in the total design of our attachments.
In the beginning, the pneumatic demolition hammer was mounted on the excavator, which was later replaced by the hydraulic hammer, which uses the power system of the basic machine.
In the use of Hydraulic Breakers, the following broad areas of application have been outlined, differing in the nature of the work:
What are the advantages of a Hydraulic Breaker over Pneumatic Hammers?
A common feature is that the beater is raised to the home position by the oil supplied by the hydraulic supply of the base machine. In the impact phase, the downward acceleration of the hammer may be provided by mechanical transmission, a spring unit, a pneumatic spring, or a pressurized fluid in addition to the force of gravity. On this basis, hammers are classified into hydromechanical, hydropneumatic, and purely hydraulic hammers.
The hydraulic system of the hammer always includes a hydraulic accumulator, which ensures the correct conditions of movement of the piston or hammer and receives the pressure pulses from the hydraulic system. The movement of the hammer mechanism is controlled either externally via a control spool or internally via a control element integrated into the control spool.
How Does a Hydraulic Breaker Work?
The piston is normally set at the bottom dead center while the mandrel moves freely. The high-pressure oil acting on the lower working surface of the piston head raises the striking piston, which moves upward until it closes the outlet gap in the upper position.
The high-pressure oil in the piston head compresses the energy storage (nitrogen gas in the tank). When the exhaust valve opens, the energy stored in the energy converter is released, pushing the percussion piston downwards with great force.
Replaceable Tools
Demolition hammers can be operated with different accessories. The most common is a demolition spike with a tapered end, which can be used for general demolition work. Flat point tools with different cutting edge lengths are an essential accessory for demolition work, but also for rock cutting and cutting tasks.
A rarely used but typical tool is the blunt crushing tools, which are mainly used for crushing high-strength, brittle materials. Depending on the technological purpose of the tools, they are manufactured with different shaft lengths.
From the hammer&#;s mode of action, it follows that it is also suitable for compaction and screed-hammering tasks if the tool is properly trained. The working tools are usually made of wear-resistant alloyed steel (manganese and tungsten alloys) or, more rarely, with a carbide insert.

How to Select Hydraulic Breaker for Excavator?
The ideal hammer is selected individually for each machine and project. It is necessary to know the weight of the attachment so that the hammer is not undersized, but also so that the loader does not tip out of its equilibrium point in the final position of the boom.
Another important parameter is the hydraulic oil pressure and flow rate per minute: if the oil supply is low, the impact value is not correct or the piston does not start up; if the values are high, immediate damage is also possible.
To determine the most appropriate device for the job, experts conduct thorough calculations based on multiple factors, including the materials to be demolished and the characteristics of the terrain.
Hydraulic breakers brought power, speed, and reliability to the construction industry, and we&#;re looking forward to seeing the next highly innovative step.
