Multi-deck machines are used in two situations:
To provide a “scalping” effect when large throughputs are required, especially if a high degree of purity is desired.
For removal of usable solids for further use (reclamation) or clarification of liquids.
The machine consists of a cast aluminium underbody (optional PVC coated body available) which performs three functions:
To support up to three screens, often termed “lawn frames”*.
To provide mounting for the 500 watt “out-of-balance” rotary vibrator motor and suspension units.
To accept the undersize from the screens and discharge via a single integral outlet pipe.
