The Challenge

The McLennan Earthmoving team, based near Grafton on the Northern Rivers of New South Wales had been battling with tailings. The company was using a series of tailings ponds to produce enough water but it was proving inefficient, so the integration of a thickener paired to suit its existing CDE EvoWash 152 system has made a vast difference to the operation’s efficiencies.

THE SOLUTION

Operating at 140 tph, the CDE EvoWash™ fine classification system washes and produces both natural and manufactured sands to produce high-quality construction sand for the concrete market. McLennan Earthmoving recently upgraded their site with the purchase of an AquaCycle™ A200 thickener. This industry-leading thickener technology has enabled McLennan Earthmoving to wash sand with longer shifts and reduced the need for manual intervention.

Water management systems are becoming a must-have for mine and quarry operations to comply with environmental regulations. Matters concerning the protection of finite resources on the planet will only become more prevalent, too.

Discussing CDE's water management solutions, Kevin Vallelly, Director of Engineering explains, “The benefits of the CDE AquaCycle™ significantly outweigh their initial investment; not only for the short period until return on investment is achieved, but for the preparedness it offers. Water management and water recycling are prevalent issues that will only become more tightly regulated and monitored in years to come. The AquaCycle™ ensures operators stay ahead of the curve while extracting maximum value from available resources and driving down operating costs.” 

The CDE AquaCycle™ thickener is available to operators around the world and is ready to complement wet processing applications in five sectors – sand and aggregates, mining, construction and demolition waste recycling, environmental applications, and industrial sands.


The Result

“Previously, we were only able to wash for a day, then we’d have to wait up to a week for the water and solids to separate in our ponds before we could begin washing again. With the addition of CDE's AquaCycle™ thickener, there is no more waiting, we can wash to our heart’s content, it has made our operation so much better, there is no comparison.” Ben Warwick, Quarry Manager.
