DRYCAKE decanter centrifuges have an energy recovery hydraulic backdrive system built around EATON Duraforce hydraulic pumps and motors for maximum serviceability. The system is designed to maximize cake dryness by using the torque exerted on the scroll to drive the system. They have a heavy-duty flame-spray tungsten carbide implementation designed for abrasives. This heavy-duty flame spray offers an advantage over tiling in that scroll maintenance intervals are sufficiently increased to be scheduled with rebalancing. Machines 20 inches and larger have the hydraulic lift-assist system that improves on the sectional cover design with a hydraulic jack to open and close the covers safely. Centrifuges come in bowl sizes up to 30 inches, in mobile and gastight configurations. 877/379-2253; www.drycake.com.
