The scroll conveyor is a core component of a decanter centrifuge. It is mainly made with duplex stainless steel or Austenitic stainless steel by centrifugal casting.
The decanter centrifuges are most of the time tasked to handle corrosive and abrasive materials , such as water water, oil sludge, chemicals, etc. The scroll conveyors are in direct contact with those materials. So the material and manufacturing method of the scroll must be selected carefully to handle the challenges. Duplex stainless steel SAF2034(DIN 1.4362), SAF2205 (DIN1.4470) or super duplex stainless steel SAF2507 (DIN 1.4469), AISI304(1.4308), AISI316(1.4408), 904L(1.4539) are mainly chosen with excellent corrosion and wear resistant properties. Centrifugal casting further improves its strength and toughness with uniform structure.
