of customers or their downstream processes,” says Du Plooy. According to Du Plooy, another major gain of installing the Combo is the flexibility. It allows Ground Breakers to produce more than two products by manipulating the amount of fines or course material. This allows Ground Breakers to spec the material according to specific client needs. Apart from the flexibil- ity offered by the conveyor system, one can also put in new screens to change the product spec. In fact, when we visited the site, CDE and Ground Breakers were work- ing on a spec change on the plant. Originally the cut size on the fine sand was 1,5 mm. Ground Breakers had a request from one of the clients who would like the cut size to get closer to 3 mm. By changing some of the panels on the screen, the produc- tion team is now able to change the cut size to the required 3 mm cut. “At CDE we put all our passion and expertise in developing equipment that is tailor-made for each client to the highest quality standards. Return on investment is fast thanks to reduced requirements for spares, highly efficient water management as well as longer and more reliable running time. “CDE’s products are specifically designed to require minimum atten- tion, minimal civils and a minimal number of operators thanks to its one-touch technology, so that it can be left to simply produce clean sand
