VDMA 12 VDMA MINING SUPPLEMENT • 2019 example, GEA machines can handle up to 100 tons of slurry per hour, which makes them much more practical for this application. A GEA Dewatering Decanter crudMaster, for example, is used to dewater the pre-thickened slurry, rotating at application-based centrifugal forces. Because the machine is lined to protect against the abrasive nature of the feed, it is very robust — ensuring op- erational excellence. Anionic flocculants are added to the process to further agglomerate fine particles causing them to drop out of solution. As a result of the additional high-speed centrifugal treatment, the cleaned water — up to 90% — is returned to the process, or if meeting the right standards, returned to the envi- ronment. The solid matter, approximately 80% dry solids, is then discharged on to a conveyor, ultimately producing a dry cake for easy disposal or reprocessing. For applications where the cleanest pos- sible water is required, the integration of a GEA nozzle disc stack centrifuge is an excel- lent solution. This centrifuge separates the process water from the fine particles and re- duces, and can even eliminate, the need for further storing the slurry. Superior separation efficiency, at high throughput capacities in continuous operation are the key product benefits. During this process, customers also have the opportunity to extract valuable ele- ments — such as gold, silver, copper, lead and zinc — which can be sold to generate extra revenue. And because the process takes place in a closed environment, the risk of chemicals or other hazardous materials leaking into the environment is restricted. High-pressure Grinding Rolls Further to the company's innovative and reliable equipment for mining, bulk material handling and minerals processing, TAKRAF is increasingly distinguishing itself as a complete service provider across the entire value chain.
