Excavator Tracks for Mining


What You Need to Know About Rubber Excavator Tracks

Excavators are also known as earth moving machines employed for use in construction work such as digging, transportation of construction material from one site to the other, demolitions etc. There are various critical components of excavators which all work together seamlessly to achieve the purpose for which they are built. One such component of these machines is their tracks known as excavator tracks.

Excavator tracks form part of the undercarriage system and are made of specially manufactured steel or rubber pads; their sole responsibility is to aid the excavator to move back and forth on rough terrain. Excavator tracks usually come in steel or rubber, and construction companies make the choice based on the type of terrain they are used on. For instance, a site with muddy earth/marshland, stones, rocks or flat earth will determine whether a steel or rubber track will be ideal.

Where can you purchase them?

There are virtual sellers offering various types of excavator tracks by sizes, types, brand new or slightly used, by brand etc. Additionally there are also well known brand retailers in Australia who have set up shop offering the potential buyer the opportunity to walk in and have a look at the varieties of machines with a sales attendant on hand to answer any questions. Common concerns potential buyers would have include the type whether steel or rubber and which would be more ideal for the terrain being worked on, the size/measurements required, specifications, after sales service etc. It helps to have these clarified especially more so if an online purchase is preferred. Also, in the case of purchasing a previously used machine, it is important to address issues such as the condition of the chains or rubber pads, life expectancy, any missing bolts and nuts etc.


In terms of costs, a few factors need to be considered before a price is arrived at; a buyer/seller would look at the number of hours the machine has been put to use (in the case of previously owned ones). There would also be critical examination of its various parts in terms of wear and tear, as well determining whether the buyer wants to rent or buy it outright. Excavator tracks are averagely priced in the ranges of $800 and $2000. Varying prices will of course be dependent on the type, either rubber or steel.


Typically excavators are built to last between 7,000 and 12,000 machine hours. This however depends on the frequency of use and maintenance. For real value for money and optimum undercarriage performance, there’s the need for maintenance; regular inspection of its components such as bolts and nuts, track tension, rock guards/rollers etc. is critical. The undercarriage area must be cleaned after every construction shift; mud and debris must be cleaned off as caked material embedded in crevices can interfere with continued smooth performance. A build-up of material can also add unwanted weight thereby reducing economical use of fuel. It is also found that sticking to appropriate digging procedures helps; what do we mean? These are outlined in the owner’s manual; following basic instructions goes a long way in reducing the burden of rather expensive replacement costs of excavator undercarriages.

Earth moving machines no doubt play a critical role in infrastructural development; these machines have contributed immensely to modern building technology we see in the 21st century. The building of these machines can only improve with time and with more complex operating systems in the near future.




Acoustic Silencers for Mining

What are Acoustic Silencers?

When it comes to reducing the noise that is generated by airflow, it becomes tricky for many domestic homes since you have to deter the air flow. However, many industries and plants have adopted sound silencers as the way out of minimizing the sound yet maintaining the air flow intact. Fortunately, the Australian market is rich in dealers of this noise reduction equipment who will gladly help you out when it comes to the selection of the silencer that suits your premises needs.

How an Acoustic Silencer Work

You may have learnt that sound travels in waves and the essence of acoustic silencers is to confine those waves and channel them through its duct. If you have been in wondering how you can turn your noisy office, house or industry into a quiet environment yet well ventilated, you got a solution; just install an acoustic silencer.

The duct of the silencer functions as a barrier preventing the larger amount of noise from escaping nevertheless there is some normal breakout noise. The amount of noise absorbed by the silencer depends on its silencer media, the open vacuum of the silencer, its length and the materials that have been used. Immediately after the sound has entered the silencer in form of waves, it expands heading to the acoustic media due to the perforations in the baffle.

There are numerous air pockets in the acoustic media which enhance molecules colliding so as to produce heat. Hence there is noise reduction in the process. The longer your duct is, the more the noise reduction can be achieved nevertheless you may increase the pressure drop. There should be a balanced pressure between the pressure drop allowed by your fan or the source of the noise and the level of resistance that the airflow creates in the silencer.

Application of Acoustic Silencers

The application of the silencer is one of the major deciding factors of the choice of the material and the specifications of your silencer. However, that should never worry you as long as you are in Australia where there are qualified engineers to advise you on the most suitable standard product tailored to suit your need. They come in different sizes, finishes, shapes, and even connection details. Most of the acoustic silencers come in two shapes: rectangular and circular.

The following are the major places where these silencers can be applied:

  • Industrial process plant
  • In boilers
  • In furnace plants
  • In incinerators and crematories
  • In diesel engine exhaust systems
  • Gas turbine and power generation plant
  • Ducted ventilation
  • Air conditioning systems
  • Ventilation discharges and also intakes
  • Reactive silencers
  • Compressors
  • Refrigeration plant

In industrial plants, acoustic silencers are used in the internal combustion engine exhausts, compressors, in pumps, and blowers etc. in addition to the reduction in the noise, the designs of these silencers take into account the volume of the air flow and the pressure. They should in no way affect the normal functioning of the industrial processes.

There are customisation and flexibility when it comes to these silencers. That’s why there are different models and shapes that satisfy differing noise, space and airflow requirements. Besides rectangular and circular acoustic silencers which are the most common, we have elbow or bent attenuators and crosstalk silencers. They come in different colours and appealing finishes. They can be made of either stainless steel or aluminium which is dependent on your environment. You don’t have any reason to lose your hearing; just apply acoustic silencers and you will be safe. These are part of Australian exhaust technology.
