Alfa Laval develops decanter centrifuge range

Alfa Laval has developed a new decanter centrifuge range for the polymer industry. The P2 range can be used in a variety of processes including dewatering and rinsing materials such as polyvinyl chloride (PVC) and polystyrene (PS), and the recovering of intermediates including polyester, polyamides and polycarbonate resins.

According to the company, the range provides efficient separation of tough industrial sludges and slurries to provide greater levels of product recovery, reduced disposal costs and lower power consumption. It can be adjusted to suit process requirements by varying the bowl speed to obtain the optimum level of G force; altering the conveyor speed to achieve the correct balance between dryness and liquid clarity; changing the pond depth; and adapting to varying feed rates.

The robust, welded box beam frame that supports the main rotating assembly is said to ensure smooth operation even at maximum rotation speeds of up to 4000 rpm and G forces in excess of 3000. The P2 also features Alfa Laval’s Direct Drive system, which provides automatic control of the differential speed between the decanter’s bowl and conveyor. The Decanter Core Controller monitors and adjusts the key operating parameters according to the solids load in the decanter bowl.
