This water powered Trommel Headerbox retrofits the HB17 Highbanker. A turgo water wheel mechanically powers the rotating 3/16" perforated stainless steel drum. The headerbox tines are spaced 1". The 3/16" to 1" washed material exits the front of the drum and is directed to the side tray.

The water, which powers the unit is recovered and used to move that material in the side tray. The bottom tray and four legs are identical to the HB17 Highbanker design. For people who already own the HB17, this is a direct bolt on upgrade. The pump you already own will power this unit. The benefit of this design is more hands off operation. Also dry or clay material is much easier to process. Unit operates at 13 PSI.
