Internally rotary drum screen description

The Internally Fed Rotary Drum Screen utilizes a direct drive system to eliminate the use of belts, chains or sprockets.

A combination of stainless-steel shoes and UHMW polyethylene wear strips replace the use of trunnion wheels reducing labor intensive maintenance.

The screening panels remove easily for regular cleaning and to allow access inside the drum without disassembling the machine.

Screening panels are available in wedge wire, perforated plate and wire mesh in various opening sizes to optimize debris removal.

Internally rotary drum screen function

Our internally fed rotary screen operates with minimal attendance.

Influent enters through the inlet and flows into a headbox.

The headbox fills and the influent cascades over the weirs and contacts two sides of the rotating cylinder screen.

As the influent hits the turning screen, the solids are caught inside the cylinder and the liquid passes through the screen into the process or on for further treatment.

Diverters on the cylinder move the solids along the length of the screen to discharge.

The unit is equipped with spray bar(s) to clean the screen.

DAGYEE has undergone continual updates to incorporate new design enhancements, and today it represents a complete family of screens.

There are 12 models with custom features specific to various applications.

Opening sizes range from 0.010" to 0.100" (.25 to 2.5 mm) and hydraulic capacities from 450 to over 13,000 GPM (102 to 2955 m3 /h).

The material standard is 304 stainless steel, but 316 and L grades are available, as well.

Heavy-duty models are available for heavy solids loadings.
