These processes suitable for the Alfa Laval decanter centrifuge include dewatering and rinsing PVC, polystyrene and ABA/AS resins, as well as the recovery of intermediates including polyester, polyamides and polycarbonate resins.

Alfa Laval says that the new range provides efficient separation of tough industrial sludges and slurries to provide greater levels of product recovery, reduced disposal costs and lower power consumption. Alfa Laval adds that key aspects of performance such as low noise operation, reliability and efficiency are based on the design of the robust, welded box beam frame which supports the main rotating assembly. This solid foundation is claimed to ensure smooth operation even at maximum rotation speeds of up to 4000 rpm and G forces in excess of 3000.

According to Alfa Laval, an important new feature is the Direct Drive system which provides automatic control of the differential speed between the decanter’s bowl and conveyor. Consisting of a new type of gearbox and variable frequency drive, Alfa Laval says that the Direct Drive enables an operator to maintain an optimum balance between solids dryness and liquid clarity. Control is provided by the Decanter Core Controller (DCC) which monitors and adjusts the key operating parameters according to the solids load in the decanter bowl. The DCC is equipped with external BUS options, enabling the operator to integrate the P2 into existing control systems.
