Franklin Miller introduces internally fed drum screen system

The Screenmaster RT is the latest addition to Livingston, New Jersey-based Franklin Miller’s fine screening systems.

It features an internally fed, rotating drum screen, providing fine screening for a wide variety of municipal and industrial applications, the company says. These include wastewater treatment, pulp and paper processing and manufacturing, tanning and slaughterhouse operations.

The RT employs a cyclindrical screen constructed with perforated metal, wedgewire or filter cloth along with a weir system. Material is fed into the unit’s inlet and distributed along the internal screen surfaces. As the drum rotates, the weir moves the solids along the screen length. Solids are conveyed to the unit's discharge, and liquids are drained via the unit's outlet port, Franklin Miller explains.

The RT is provided in a choice of models with drums up to 60 inches in diameter and up to 156 inches in length.

The Screenmaster RT is constructed for smooth operation and long life, Franklin Miller says. It is supplied in corrosion-resistant T304 or T316 stainless steel and includes a choice of screen openings from 500-by-500 micron (filter cloth) up to 6-millimeter perforations. Screen segments are readily accessed from the outside of the unit after removal of the exterior panel enclosures, the manufacturer says.

The RT is provided with internal as well as with external pressure nozzles to keep the screen clear. A control system is typically provided in National Electrical Manufacturers Association (NEMA) 4X enclosure.  

The unit is easy to install and simple to maintain, according to Franklin Miller.
