SCREENMASTER RT Rotary Drum Screen
The SCREENMASTER® RT internally fed rotary drum screen employs a rotating drum to provide effective fine screening of a variety of materials with a simple and reliable design. This unit employs a cylindrical screen constructed with perforated metal, wedge wire or filter cloth along with a weir system. As the material is fed into the unit’s inlet, it is distributed along the internal screen surfaces.
As the drum rotates, the weir moves the solids along the screen length. The liquids are discharged out the unit’s bottom. The solids are conveyed to the unit discharge flange. The RT is provided in a choice of models with up to 60” diameter drums up to 156” (4m) in length.
Construction
The SCREENMASTER RT rotary drum screen is ruggedly constructed for smooth operation and long life. It is fully constructed in corrosion resistant T304 or T316 Stainless Steel. The RT is provided with a choice of screen openings from 500 x 500 micron (filter cloth) up to 6 mm perforations. The perforated screen segments are removable from the outside of the unit by opening the access panels.
The unit is provided with internal as well as external high pressure nozzles to keep the screen clear. An optional brush assembly can be provided. Each unit is typically supplied with a PLC based control system housed in a NEMA 4X enclosure.
