Vertical decanter centrifuges with automatic bottom discharge from the bowl model DRC-BO

Product catalog summary

Overview: The document provides technical specifications and operational details for the DRC-BO model vertical decanter centrifuges, designed for automatic bottom discharge from the bowl. These centrifuges are used for purifying industrial sludges, wash waters, cutting fluids, and cooling liquids across various industries.

Specifications:

Model DRC 30-BO: Diameter: 300 mm, Total Volume: 15 liters, Sediment Volume: 8 liters, Speed: 3000 rpm, Dimensions: 1.47x1.15x0.95 m, Motor Power: 2.25 kW.
Model DRC 45-BO: Diameter: 450 mm, Total Volume: 48 liters, Sediment Volume: 16 liters, Speed: 2500 rpm, Dimensions: 1.93x1.42x1.26 m, Motor Power: 7.5 kW.

Operating Principle: The centrifuge operates automatically, with a rotating disc feeding the slurry at the same speed and direction as the bowl to minimize turbulence. Centrifugal force separates denser particles, forming a 'cake' on the bowl wall, while purified liquid overflows for discharge.

Sludge Discharge: A patented device detects sludge mass, optimizing bowl filling and preventing overfilling. Upon reaching a set mass, the feed stops, and the bowl's rotational speed is adjusted to discharge solids through a pneumatically actuated chute.

Contact Information: The document lists contact details for Rousselet Robatel's offices in France, the UK, the USA, and Germany.

Vertical decanter centrifuges with automatic bottom discharge from the bowl model DRC-BO-2

• The slurry is fed using a rotating disc that rotates at the same speed and direction as that of the bowl (minimized turbulence). • Under centrifugal force (1500 to 2200 x G), the denser solid particles migrate to the bowl wall and accumulate into a "cake". The rotating baffles divide the bowl into four "calm" zones and guarantee that the slurry is at the same rotational speed as the bowl wall yielding a faster/more efficient separation. • The purified liquid is discharged by overflow. • A special device detects the effective sludge mass inside the bowl. This patented system has the advantages...
