This deep-pond decanter centrifuge has been customized for clear clarification and dewatering in chemical and mineral processing applications. The solid-wall bowl has a cylindrical section for efficient clarification of the liquid and a conical section for drying the solids. Due to the centrifugal forces, the solids are flung onto the inner bowl shell and are transported by the scroll to the solids discharge. On decanter type chemMaster series, the clarified liquid is discharged under pressure by use of a centripetal pump. CIP-compatability of the decanter can be assured. The housing consists of a frame with supporting feet, protective plates and catchers for the discharged phases.
Design for dewatering, separation and washing
• All product-contacting parts are made of high-alloyed duplex steels, super duplex steels or Hastelloy C276. Depending on the application, the gaskets are made of NBR, FKM, FFKM, EPDM
• Chemical cleaning after separation possible
• Explosion-protected centrifuges available: · Gas-tight decanters from GEA comply with the test criteria of the strict European ATEX standard or other EX regulations · The oxygen atmosphere in the separator is displaced with inert gas and the excess pressure is maintained during operation to assure inert gas blanketing.
• Available for temperatures up to 130 °C.
