Aggregate Industry Case Study: LafargeHolcim Group: Aggregate Industries, Torr Works Quarry
“We got one in the workshop, and it is working REALLY well”
About the customer
Aggregate Industries produce and supply an array of construction materials including everything from aggregates, asphalt, ready-mix concrete and precast concrete products. Additionally, they produce, import and supply construction materials, export aggregates and offer national road surfacing and contracting services. They operate 200 sites and employ around 3,700 people.
The quarry was suffering with moisture in the airlines in numerous places at the site. For instance, the pneumatic hand tools and plasma cutting machine in the workshop were receiving extensive damage from liquid water in the compressed air lines. As a result, pneumatic hand tools would have to be frequently replaced along with various components like the tips from the plasma cutting machines. This was resulting in unnecessary equipment wastage, avoidable costs, and production downtime.
In the winter months, issues with moisture would intensify and cause further problems at the site because the liquid water would freeze causing ice blockages in the lines which proved difficult to rectify because the addition of antifreeze lube oil (to get rid of the ice blockage) adds yet another damaging liquid to the lines.
Why did Aggregate Industries choose Expel?
Considering both the limitations of a dryer and hefty price tag it carries, Interim Mechanical Maintenance Manager Calum Barnett wanted to explore more effective solutions to completely remove the source of the problem.
Calum Barnett immediately recognised the benefit of the Expel units. He knew Expel could positively impact the site in ways that other filtration products couldn’t compare to. After installing Expel, Callum was so impressed with the results that he has meticulously logged the improvements and results that the site has had thanks to Expel so that he can share this information with other sites and colleagues to keep Aggregate Industries’ sites as efficient as possible.
