10 - 5000m3/H Mechanical Bar Screen 500MM – 3000mm Rotary Drum Screen

Rotary Drum Screen
Product Overview

The Rotary Drum Screen is a high-efficiency solid–liquid separation device designed to continuously and automatically remove suspended solids and debris from water.
Rotating drum screening provides precise filtration, stable operation, and minimal maintenance, making it ideal for municipal wastewater, food processing, paper, and chemical industries.

Working Principle

The influent water flows either from the inside or outside of the rotating drum. Solids are trapped on the screen surface while water passes through the openings.
As the drum rotates, the collected debris is carried upward and automatically removed by a high-pressure spray or scraper.
The waste falls into a conveyor or bin, and the entire process runs continuously with full automation.

Main Components

• Rotary Drum: Made of wedge wire or perforated plate, high accuracy and durability.

• Frame: Stainless steel structure, rigid and corrosion-resistant.

• Drive Unit: Gear motor ensures stable drum rotation.

• Cleaning System: High-pressure spray or scraper for automatic cleaning.
