CDE launches largest version of Combo wet processing plant

The new Combo X900 can process 500tonnes of material per hour

CDE has unveiled the largest version yet of its Combo all-in-one wet processing and water management solution.

The new Combo X900 features an increased capacity of 500tonne per hour (tph).

Kevin Vallelly, director of engineering at CDE, said that the globally available new version has been engineered specifically for materials processors in the Americas. “With our new Combo X900, we’ve doubled its capacity and created a next-gen solution for materials processors across North America and Latin America,” he added.

CDE launched the first version of the Combo plant at bauma 2019. CDE group managing director Tony Convery said the company has now sold over 2,000 plants globally and claimed it is the largest wet processing plant provider in the world.

Vallelly said that 15-20% of each Combo plant is customised to meet the requirements of the specific customer.

He added that the Combo X900 can process 500tonnes per hour of feed material. This includes natural sand and crushed rock, containing unwanted clay, silt and other organic contaminants to extract quality in-spec washed and graded sand products that are market-ready straight from the belts.

As well as its increased capacity, the Control Cabin of the new X900 has been repositioned to sit on top of the water tank, a design decision Vallelly says is directly influenced by the North and Latin American markets.

“In these regions, plant and machinery are subject to major temperature extremes and fluctuations,” he says.

“By positioning the Control Cabin on top of the water tank we’re able to better protect the operational heart of the plant and offer a solution that can be adopted throughout both North America and Latin America where high and low temperature extremes are recorded.”

CDE says that, while traditional washing systems typically have a separate standalone water tank, the new Combo X900 has integrated this into the design of the AquaCycle thickener tank. It states that this results in a peripheral wall for water storage, which has significantly reduced the overall footprint.

The Northern Irish company says that this provides customers with almost total independence of water supply and minimises the requirements for costly site engineering due to its significantly smaller footprint which is, on average, 30% smaller than other traditional wash plant setups.

“Traditional washing systems would typically consume up to 15 times more water than that required for the Combo X900,” says Vallelly.

The X900 enables materials processors to wash more than 500tph with only 800gpm (gallons per minute) – about the same amount of water that would be required to wash a truck, according to CDE.
