Dynamic Centrifuge 

The residual humidity of the material before further processing in the densifier or the extruder is an essential element of the energy consumption of the regeneration plant. The Dynamic Centrifuge has proved to be the machine best suited to dry the material, which exits the tank with a humidity of up to 50%, to a residual humidity of  4 -5 % for LDPE or PP Film (even with a contant of about 20 % stretch) and ca 1 -2 % for rigid material such as  HDPE or PP. The mechanical drying is superior to the thermal drying concerning energy consumption. A  Test Report indicates the results achieved with the Costarelli Dynamic Centrifuge 850/10. 

The Dynamic Centrifuge is designed according to the principles of a horizontal centrifuge  and includes the combination washing and a subsequent drying of shredded  plastic material. It is normally installed downstream to a  Turbo-Wash and a Sink-Float-Tank.

The  Dynamic Centrifuge is designed for special ruggedness (weight of the rotor about  2 t., total weight about  6 t.) and high reliability. The drying effect is caused by the high centrifugal force (1800 U/min), the impact of the rotor blades and the mutual friction of the rotating plastic material. At the same time paper and cellulose is separated from the plastic material and is eliminated with the water. This content can be up to  40% (e.g. at the treatment of industrial waste).

The Dynamic Centrifuge is equipped with a slow counter rotating sieve-basket. The impact of the material causes a  self-cleaning effect.

Design:

  • Dynamically balanced rotor and blades
  • Interchangeable Blades, with abrasion resistant plates bolted to the blades
  • Counter rotating self cleaning basket, ? 850 mm
  • Oil-cooled roller bearings
  • Easy disassembly with mounted rotor blades
  • Water in closed loop
