CDE Asia has announced an expansion of the mobile product range for the manufactured sand washing market with the introduction of the new Combo X150 washing system that integrates all washing process from end to end in a single compact mobile unit. The Combo range offers cutting edge classification and water recycling technology that provides accurate control of silt cut points and effectively delivers high quality sand for the fast growing construction projects in the Asian marketplace. According to the company, this not only maximises the production of high quality manufactured sands but also reduces the water requirement for the mobile washing plant by 90%.

Combo requires a small fresh supply as opposed to traditional systems which typically consume 10-15 times more water. "This is what makes the Combo the most 'eco-friendly' sand washing system anywhere in the planet," explains Mr. Manish Bhartia, Managing Director of CDE Asia. "The other significant advantage is low power consumption of 0.75kW per ton of feed - at just 151 kW maximum power rating - Combo X150 is the most power efficient machine using clean energy and demonstrates how CDE is committed to helping our customers achieve the highest sand and aggregate specifications using washing technologies while also ensuring minimal environmental impact."
An intelligent remote monitoring platform is also on board the Combo X150, as an option. This platform enables real time measurement of critical functions, storage of equipment-usage data for accurate diagnosis during service calls, and broadcast of user warnings for preventive/service requirement. The tailored system assists users in getting maximum plant performance with maximum equipment availability ensuring customers can meet and exceed their production targets.
Mr. Bhartia highlights - "This new system with higher production capabilities of 150-200 tons per hour provides an even more attractive proposition to the maturing washed manufactured sand market place in India that is now available in 18 cities of the country. Our washed manufactured sand is now a preferred choice and viable alternative to river sand. With the spurt in new construction projects, the larger companies are regularly demanding high capacities to meet their sand demand and Combo X150 provides a perfect answer for their need of integrated mobile wash systems that maximises water use. This new generation of plant will allow operators the flexibility of producing concrete or plaster sand simultaneously from one machine."

A feeding system inputs the feed material into the washing unit, which effectively removes excessive minus 75 microns fraction from the feed material. The material is then forwarded on to the dewatering unit, which simultaneously delivers washed, dewatered, and well-graded sand products of two grades concrete and plaster sand - via integrated stockpile conveyors. Waste water from the system is transferred to the inbuilt recycling unit, where the solids are separated from the water. The recycled water is circulated back into the plant and final waste silt is removed from the recycling unit in the form of highly concentrated sludge for easy disposal through various sludge management techniques designed by CDE.
Combo range's new modular design, the mobile Combo X150, ensures rapid deployment and minimal plant footprint. This innovative path-breaking design has been jointly developed at the R&D Centre of CDE, located at both Northern Ireland and India.
