Winter Maintenance Time.
Inheriting equipment as a result of M&A presents new challenges to plant and equipment departments. Hear how Aran focuses on developing strong relationships with machine owners to help them achieve successful outcomes in terms of maintenance and operation of inherited equipment.
Windsor ON Canada pavement construction company, Coco Paving, has an ever growing business and equipment fleet. As a result of acquiring other construction companies in the region, Coco inherited an Aran ASR280E series mobile mixing plant a few years ago.
The ASR280 mobile mixing plant is a key component of Coco Paving’s asphalt production. Quarried materials sourced for many of Coco’s projects require the addition of lime (1%) prior to use in its asphalt plants. Without the accurate addition and homogeneous distribution of lime, the production of a successful pavement would not be possible. Producing 150,000 tonnes conditioned material each construction season requires the mixing plant to be operated up to 5 days each week, often for double shifts to meet project demands. This level of equipment utilisation limits opportunity to service and maintenance.
During a recent visit to Coco Paving’s maintenance facility Aran performed an informal equipment audit ahead of the next construction season. When major maintenance is restricted to one period per year (winter), the extent of the work required can be significant. It is not uncommon for some plant operators to focus on pushing material through the mixer towards the end of the project or season and sacrifice the condition of the mixer. Thus, mixer effectiveness, efficiency and the resulting mix quality and energy consumption are compromised.
To their credit, the maintenance team at Coco have been thorough and resourceful. Whilst their familiarity of the machine was initially limited, with Aran’s help, they have are coming up to speed with the function of the plant and areas of the plant requiring attention.
This winter (2015/16) this machine is receiving a full engine and mixer rebuild.
Aran has assisted Coco with the replacement all major components for mixer, including new shafts and wearing components, special housings and delivered recommendations for other system service.
We always want to learn from Aran machine owners, operators and maintenance teams. Learn about their experiences on the job, in the workshop or at the boardroom table. We have a lot to learn and a lot of experience to contribute.
As an owner of an Aran machine, you not only have the support of a committed and experienced team, but a network of passionate and skillful operators.
If you have an operational or maintenance challenge with your mixing plant, get in touch. We’d like to connect with you and help you achieve the very best from your equipment and projects.

Often it is more efficient and cost effective to replace mixing shafts during heavy maintenance.
We recently visited an Aran modular mixing plant which has proven its weight in gold, producing cemented backfill for the Gossowong underground mine on remote Halmahera island in Indonesia. Aran visited this remote mine site to perform a condition review of the plant and make recommendations for to ensure its continued successful operation for another decade.
It was impressive to see how well this machine has been maintained after 10 years of highly ulitized operation. Producing up to 150m3/hr of backfill for schedule critical mining, this plant is an excellent example of high availability as a result robust equipment design and good attention to cleaning and maintenance.
The Gossowong gold mine extracts ore from very narrow seems in areas of fractured and highly stressed rock. Located in a highly seismic region, this underground mine is presented with many risks to the safety of underground workers. In order to safely and efficiently extract ore, narrow stopes are created, then quickly filled with cemented paste. This cemented paste must be strong enough in allow continued mining operations. Target strengths in some areas can be as high at 2mpa in 7days. This strength requirement can demand a mix recipe with up to 24% cement for a 230-260mm slump paste.
The Gossowong mine utilises volcanic dust, Tuff, as the primary product in the fill material. This fine dust like material is incredibly porous, capable of holding up to 35% moisture. When wet, it can be somewhat challenging to handle. Additionally the water retained within the Tuff can make the goal of optimising the cement to water ratio, difficult. Accurate cement addition to the paste backfill mix is critical, not only to ensure fill underground is structurally competent, but cost of the fill is tightly contained.
The Aran backfill plant receives screened Tuff material into a metering hopper which accurately meters the material into the mixer. Cement, delivered to the mine site in bulk bags, is unloaded and transferred into the mixing plant silo. Accurately metered cement is then added to the mixer with water for mixing. The Aran twin shaft, high intensity mixer combines these ingredients, before delivery into the underground reticulation pipeline system.
Whilst the machine’s external appearance represents a plant exposed to the tropics for ten years, mechanically and electrically it is still in excellent condition. Of course, over ten years of product development, there are many possible upgrades which can be installed on this older machine however, what currently exists on this site is a credit to the owners and operators passion for care and maintenance. Very few system and hardware upgrades are needed.
If you would like to learn more about what makes Aran mixing systems so accurate and reliable, please ask us. If you have a project challenge you are confronted with, we would like to listen to your story.

Boral Recycling use an Aran Modumix mixing plant to deliver pavement construction materials to Sydney projects with a solid respect for the environment.
Western Sydney is the recycling center for Australia’s largest city. Receiving many thousands of tonnes each day of old construction materials from building and pavement demolition sites, Boral will crush, screen and stockpile materials for reuse. These processed materials are later delivered to new projects either as fill or stabilised road construction material. The Aran mixing plant is a key to the success of this business.
Road construction specifications require very accurate dosing of binders and water to produce a constructed pavement with consistent density and strength. This can be challenging to achieve with recycled materials containing residual cement. Boral elected to install an accurate, high production mixing plant in 2008 to service the rapidly growing need for recycled material in Sydney and beyond. Considerably larger that what was needed in 2008, Boral identified the growth in Sydney would demand a high production plant for the future and purchased a second hand Aran Modumix II modular mixing plant. With a proven history of mixing large volumes of material very accurately, this was the perfect choice for Boral. In years prior, this mixing plant, along with an identical twin plant, produced over one million cubic yards of Roller Compacted Concrete for a dam in South Carolina, USA. Prior to installing the plant in Sydney, Aran refurbished the machine, including the installation of a new control system and a third silo and metering system.
I recently visited this machine just after its 13th year, with 7 years operating at Boral’s facility in Sydney. This machine is operating every day, producing material at rates of 420 cubic meters per hour or greater, with binder contents of 0-11 percent. The accuracy of the cement metering is an impressive 0.033% variance across milestone targets. This is easily within the specified guidelines and a good example of the Aran SiloFeed system to perform on a 13 year old machine. This accuracy gives clients confidence they are receiving a quality product and Boral the confidence that they are not only producing a product on specification, but doing so efficiently.
High production rates is not only geared for processing orders for material quickly, it also allows Boral to charge trucks very rapidly and maintain a clear traffic flow around the plant. Speed and efficiency helps this site run smoothly and successfully.

ASR200 located near Roma, QLD, Australia
It is always great to hear how reliable Aran mixing plants are. This week involved a visit an Aran mobile mixing plant operating in the western Queensland Australian town, Roma. This ASR200 has been working hard since it was manufactured in 1984. With a few upgrades along the way, this machine is still producing good quality product at 300 tons per hour. At this site in Roma, it is completing a 300,000 ton project, producing road base for local highway upgrades.
Once this job has finished, we’ll be helping the owner get the plant ready for the next big project. Fortunately there is not much to do, only ensure the silo feed and control systems are in top shape.
If you would like to get your machine performing its best, give us a call. We get a lot of satisfaction seeing old pugmills running like new, if not better!
Recently I was in Quebec to visit two Aran mobile plants owned by Cement Quebec. Two ASR250X machines, each with three aggregate feed hoppers capable of producing 400tph of mixed product. The machines are operated and maintained by les Carriers St Dominique.
This was a great opportunity to meet with both companies and hear about the interesting RCC work being carried out in Canada. From small to large projects, these machines solely mix Roller Compacted Concrete. These guys really know how to build strong and robust pavements in a cost and time efficient way.
Winter time in Canada is the perfect time to maintain the machines ahead of the next construction season. These two machines are about 25 years old, not that you can tell. A new coat of paint and comprehensive mechanical maintenance, these machines are almost as good as new. They perform a new also! Cement feed accuracy at 0.0125% over 800 tons. When you are consuming cement at 54 tph, accuracy like this ensures material costs are well contained.
If you’d like to hear some more about the innovations Cement Quebec are employing towards the development of Paver Compacted Concrete ( or RCC), let me know.
