CDE launch new Aquacycle thickener

Company introduces high-capacity A1500 thickener incorporating new four-arm rake mechanism

CDE have announced the launch of the Aquacycle A1500 thickener following its installation at a site operated by Creagh Concrete in Northern Ireland.

According to CDE’s senior design engineer, Paul O’Neill, the addition of the A1500 to the Aquacycle range represents the completion of a significant R&D programme and will ensure increased opportunities to specify thickeners on the CDE washing plants installed throughout the world.

‘The A1500 significantly increases our opportunities to win business in the many markets in which we operate,’ explained Mr O’Neill. ‘As we make progress in areas like South Africa and Australia, the A1500 allows for the introduction of a single unit on projects with high processing tonnages. Up until now multiple machines were required to deal with the high processing throughputs that are typical in these areas.’

The A1500 has a capacity of between 1,000 and 1,500 cubic metres per hour depending on the material being processed. ‘In a typical sand and gravel application the dirty water processing capacity will be approximately 1,500 cubic metres per hour,’ said Mr O’Neill.

‘On ore processing applications, capacities will be determined on an individual project basis to allow for the effective treatment of sludge containing material with a significantly higher specific gravity.’

One of the many product developments on the new Aquacycle A1500 is the redesign of the rake mechanism which is employed to condition the settled sludge within the thickener before it is discharged to the next phase of processing or the settling ponds.

‘The new four-arm rake mechanism ensures maximum settlement of the sludge within the thickener while also ensuring its density is optimized for effective discharge via the integrated slurry pump,’ explained Mr O’Neill.

Following the introduction of the new rake mechanism on the A1500, the design will now be introduced across the full Aquacycle range.

In recent years CDE has reported a substantial increase in the specification of Aquacycle thickeners on their global washing plant installations. ‘More than 80% of all our projects now include some form of water treatment across all feed materials and geographies,’ said CDE sales director Enda Ivanoff. ‘The launch of the A1500 will allow us to realize further sales opportunities in the coming months.’

The Aquacycle A1500 has a tank diameter of 15m and is constructed with the elevated cone design present across the range. The full Aquacycle range covers capacities from 100 to 1,500 cubic metres per hour across five models.
