Sharples P600 Decanter Centrifuge

Sharples P600 Decanter Centrifuge

The P600 decanter centrifuge is a fixed rig housed within the Secondary Processing Laboratory of the BEACON Pilot Plant Facility at IBERS Gogerddan, Aberystwyth. This is a refurbished unit purchased specifically the BEACON project, previously used for the separation of suspended biomass.

Technology summary:

The key features are:

  • Stainless steel bowl 152mm diameter x 353mm long.
  • Belt driven by three phase 3.5kW motor with starter control on unit.
  • 51mm pitch single lead hard surfaced conveyor (scroll) driven via a fixed speed gearbox with torque arm.
  • Maximum 6000 RPM (~6100 G).
  • Mounted on 1.2m high stand with continuous solid and liquor take off.
  • >1000 litres/hr throughput.

Decanter centrifuges consist of cylindrical and conical bowl sections rotating on pillow block bearings. Separated solids collect on the periphery of the cylindrical rotor and are scraped to discharge sludge ports in the conical bowl section by means of a conveyor or scroll of the same contour as the bowl. Separation can be arranged for either clarification or purification dependant on the weight and extent of solids in the feedstock. The relative speed between the bowl and the scroll is controlled by a planetary or cyclonic gearbox integral to the decanter centrifuge. The scroll is generally hard surfaced for wear and erosion protection.
