Rotary Drum Screen – Precise Design for Liquid&Solid Separation

Rotary drum screens, also known as wedge wire rotary drum screens, are an indispensable part of rotary screen machines. By filtering materials through rotation, our rotary drum screens stand out with their robust design and all-stainless steel construction, minimizing equipment downtime and maintenance costs.

The end of the drum screen is designed with a welded flange or welding ring, making it easy to install on the drum screening machine. In addition, in high-pressure environments, we also offer a solid rod option to ensure exceptional filtration performance. This means that our rotary drum screens not only perform excellently in conventional settings but are also reliable in more challenging conditions.

Different types of rotary drum screens meet various application and installation requirements.

Rotary drum screens are generally divided into two types: External Fed and Internal Fed:

  • External Fed: Wastewater or materials to be treated are introduced from the outside of the rotary drum screen. This design is suitable for certain specific wastewater treatment and industrial filtration applications.
  • Internal Fed: Wastewater or liquids are introduced through the central axis of the drum. This means that the liquid enters through the inside of the rotating screen and undergoes solid-liquid separation. This design is commonly used for solid-liquid separation as well as other industrial applications that require efficient filtration.
