Founded by Trevor & Jan Dunstan in 1977 as Aran Enterprises Pty Ltd and Dunstan & Partners Pty Ltd, the first Aran group companies gained early recognition for innovative and functional design of machines and systems for the processing and storage of quarry products, grain, and stock feed. NO COMPROMISE standards of engineering integrity and quality were pivotal to the Aran brand from the beginning.
Aran soon developed a range of standard products which included hot mix asphalt plants, aggregate screening plants and concrete batching plants. It was the mobile Aran ASR 200 mixing plant for treated road pavement materials for which the name Aran became best known. By the mid eighties this compact high performance family of machines was in international use. Aran machines were more versatile than earlier alternatives and were much more accurate and uniform in their ability to meter cement.
Modular machines were added to the mobile wheel mounted range in the late eighties. Since the second generation MODUMIX II-4 modular machines family was introduced in the mid nineties, these high performance models have become the dominant models. From beginning as a general mechanical engineering company, Aran became recognized as the specialist in high performance “through (continuous) mixing” technology.
In the years that followed, the Aran company structure has changed to suit new environments and different operational demands. Although originating in Australia, Aran products are used widely around the world in many different applications. Aran machines have been built under licence or contract in the UK, Germany, the USA and China.
Aran was the first to develop a fully self contained, self erecting, mobile continuous mixing plant with workable silo and hopper capacities all on one trailer unit in 1978.
The fully enclosed cleated belt feeder for metering fine particulates such as cement was an Aran invention of 1979. It set new standards of accuracy and repeatability for this process.
In 1984 Aran pioneered the use of continuous mixers for RCC dams and demonstrated the superiority of this process on the second all RCC dam which was built in 1984. In 2004, two Aran MODUMIX II-3 machines set a new world record for RCC placed on a dam between forms by achieving 14,630 cubic metres in a single day (20 hours).
In 1987 Aran was amongst the first suppliers of construction mixing plants to develop machines based around modules strictly in conformance with cellular shipping container rules.
The current Aran mixing plants are used on all continents. Even the older plants built more than 20 years ago are still making their contribution to infrastructure development. Some are now in fixed locations doing the same kind of work every day. Others are regularly moved from site to site mixing all kinds of materials and between them have undertaken thousands of different projects.
Modern Aran plants redefine the concept of ultra compact high performance mixing plants. Today the greatest proportion of cement bound and stabilized pavement materials for the vast network of highways in modern China has been mixed by machines built to Aran licenses. Aran asphalt batching plants and concrete batching plants are respected names in China. From the mid eighties Aran machines set the benchmark for mixing contaminated soil and recycled construction materials in the USA and Europe where their high mobility and superior performance were unmatched. Aran has made a major contribution to cleaning up the environment.
Aran has consistently demonstrated product and design leadership in its field of expertise. Our displayed knowledge in construction techniques and materials handling methods in addition to our capacity to incorporate these ideas integrally with the various other project factors has drawn the attention of project designers, clients and specification reviews for systems.
Aran mixing plants have the widest global distribution of any machine of this general type and are used in the widest diversity of different application.
