Screw Classifier

The Tuke and Bell range of Screw Classifiers are a complete, free-standing unit, ideal for effective separation of grit from organic and other matter. A weir allows the separated organics to return, whilst grit is conveyed via the screw to a discharge point for disposal.

A wash water pipe connection and spray-bar are included within the classifier body for cleaning of the grit.

The Tuke & Bell Screw Classifier incorporates the following features: -

  • Freestanding tank construction simplifies location.
  • Universal tank handing simplifies pipe work connection.
  • Fully enclosed screw with lockable, removable inspection covers.
  • Wash water spray bar for grit polishing.
  • Designed to accept multiple feeds.
  • Can be fitted with Hydrocyclones for handling high pumped feed flows.

Typically the Screw Classifier is used in conjunction with a Vortex Grit Trap and together carries out the complete grit extraction process whilst allowing greater flexibility of plant layout.
