sizes of operations – and anticipates future needs – from 30 to 250 tonnes per hour. A plug-and-play system that allows for unrivalled control of silt cut points thanks to a highly efficient cyclone-based process, the Combo ™ technology prevents loss of sand in the overflow and loss of valuable fines to ponds. Every grain of valuable product is retained in the system. “The Combo all-in-one materials washing plant marks a giant step towards helping customers resolve various issues from the bulkiness of stick-built structures to sand feed availability,” says Thomas Doyle, CDE product development engineer and Combo expert. “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,” adds Doyle. “With all modules working as a closed circuit, sand production is seamless, efficient and in specification every time. As valuable fines lost to ponds is a thing of the past, operators can reduce the footprint of their ponds, save of their

flexibility and guaranteed results, the Combo washing and water recycling solution offers presents the ideal alternative to sand screws and bucket wheels, with fast return on investment and the assurance that not one ounce of valuable material will be lost.” “Pioneering a new materials washing era, the Combo does not just benefit operators in terms of high efficiency and better-quality production, it also provides, in its compact but powerful way, a real answer to some of the most pressing socio-environmental issues of the 21 st Century by offering an alternative to illegal sand dredging that contributes to both the protection of our natural resources and the safety of those whose livelihoods are tied to the sand business,” adds Govender. “As the CDE Southern Africa team continues to grow, we are more than ever ready to provide each customer with a bespoke washing solution that will significantly increase their production with a fast return on investment, and we are even more connected to our market thanks to after-sales service excellence and engineering support right on our customers’ doorstep,” concludes Govender. b

The CDE Combo system is also designed to exceed health and safety standards, incorporating a range of features for easy, quick and safe access for plant maintenance. Working conditions are made safe through automatisation of the plant via an on-board control panel housed in a double door stainless steel enclosure to ensure suitability of application for outdoors, even in the harshest environments. In conclusion, Govender says: “For South African quarry operators, for
