Each Combo modular plant is bespoke to the client’s needs, with a range of options that allows for tonnage flexibility to suit all sizes of operations – and anticipates future needs – from 30 to 250 tonnes per hour.

longer-term resistance to erosion of the final construction material.” The patented Combo materials processing solution offers the opportunity to produce high-quality sand products, including from a crushed rock feed, freeing operators from having to rely solely on the extraction of natural sand. The technology, unique to CDE, is taking the wet processing industry by storm, breaking conventions to bring a fresh approach to sand washing. A compact installation that fulfils all wet processing needs from feed to final materials, CDE has combined its most advanced technological feats within a simple, one-touch system. With fast set up within small or large footprints and delivery of in-spec products every time, all the time, the Combo ™ is fast becoming the wet processing sensation of 2018 thanks to its innovative design and technological make up. All for one and one for all The Combo features patented technology that combines feeding, washing, grading, dewatering, water recycling and stockpiling onto one compact chassis; it allows to run the full feed to the final product process at one touch of a button, with up to three in-spec final materials ready for market straight from the belts – two sands and one aggregate product. Each Combo modular plant is bespoke to the client’s needs, with a range of options that allows for tonnage flexibility to suit all

“All six processing stages of the Combo plant have been conceived with low energy consumption as a must, while operators also benefit from exceptionally economical water consumption, with an incorporated water management unit that recycles up to 90% of used water directly into the system.”

at the centre of the materials industry’s concerns, the features of the CDE Combo system ideally match quarry operators’ requirements.” When natural sand becomes optional Indeed, primary sources of natural sand, river beds and deserts are now increasingly being protected by governments that closely monitor sand mining and sanction illegal operators. Often, when unable to mine for natural sand, some operators resort to using unwashed crusher fines to produce cement and mortar at low cost, producing poor to very uneven results. But it is not a case of ‘either - or’, natural sand or unwashed crusher fines. For those who wish to produce sand at consistent quality and quantity levels, with the

option to choose specific grades, materials washing is the simple and accessible solution for their operations. “The ever-growing need for quality sands, combined with depleting reserves of natural sand, has compelled South African construction companies to consider manufactured sand as a means to increase their returns on investment, increase product quality and adaptability, and stay one step ahead of their competitors,” says Govender. “While unwashed crusher fines continue to be used in operations that require minimal grade specifications and where reduced costs are prioritised over quality, sand and aggregates washing is now widely recognised as the best value-for- money option by those wishing to achieve a high-quality product that will guarantee
