For chemical and mineral products
Dewatering Decanter crudMaster
For clear clarification, liquid separation and solids dewatering in chemical and mineral processing applications. The heavy or light liquid phase is discharged under pressure by use of a centripetal pump while the other liquid phase is discharged by drain tubes. CIP-compatability of the decanter can be assured.
This deep-pond 3-phase decanter centrifuge has been customized for clear clarification, liquid separation and solids dewatering in chemical and mineral processing applications. The solid-wall bowl has a cylindrical section for efficient clarification of the liquids 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 crudMaster series, the heavy or light liquid phase is discharged under pressure by use of a centripetal pump while the other liquid phase is discharged by drain tubes. 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.
Features & Benefits
- 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.
GEA summationdrive
- Drive with intelligent kinematics for high differential speeds and torques which enables processing of high solid capacities
- Full torque up to the maximum differential speed; this allows processing of high solid capacities
- High efficiency of the drive as the variable speed motor feeds in energy instead of braking
- Automatic adaptation of the differential speed by means of frequency-controlled motor
- Good accessibility to all drive parts
- Changing the differential speed without replacing the complete gear
- All product-contacting parts are made of stainless steel
