Corrosion Resistant Rotary Drum Screening Machine Low Failure Rate

Corrosion Resistant Rotary Drum Fine Screen Uniform Screening Low Failure Rate

Brief Description

The surface undergoes special anti-corrosion treatment, resisting acid, alkali, and salt spray corrosion, making it suitable for coastal or chemical areas. The scientifically designed screen surface distribution ensures uniform material passage and avoids localized overload. It performs exceptionally well in seawater desalination pretreatment and metal surface treatment wastewater treatment, ensuring long-term reliable system operation.

Product Overview

Crafted for efficiency and reliable functionality, our Rotary Drum Fine Screen delivers a full-package solids separation solution for heavy-duty wastewater conditions. It effectively removes fine suspended solids including scum, short fibers and particulate matter, producing clear effluent and compact, dewatered screenings.

Working Principle

Designed for maximum throughput and 24/7 operation, this system integrates interception, cleaning, lifting, and dewatering into a single uninterrupted automated workflow for heavy-duty wastewater treatment.
1. Interception
The 35-degree angled drum rotates at a constant speed in the channel, enabling fine screen panels to intercept solid particles from continuous wastewater inflow without flow disruption.
2. Cleaning
Nonstop automatic cleaning accompanies drum rotation, with heavy-duty nylon brushes and high-pressure sprays working together to clear solids instantly, preventing clogging and maintaining high throughput.
3. Lifting & Conveyance
Recovered solids are directed to the integrated screw conveyor, which lifts screenings rapidly out of the water flow to keep pace with continuous wastewater input.
4. Dewatering & Discharge
Screenings are compacted under pressure to minimize moisture and volume quickly, with dewatered cake discharged continuously into transport units. The closed setup controls odors and sustains hygienic operation.

Product Parameters

Key Design & Performance Features

*Integrated All-in-One Design: Combines screening, conveyance, washing, and dewatering in a single, compact footprint, saving space and simplifying installation.
*Fine Screening Capability: Effectively removes particles down to 1-6mm screen apertures, protecting sensitive downstream equipment (e.g., pumps, MBR membranes).
*Low-Headloss Operation: The 35-degree installation and optimized hydraulics minimize upstream water level impact.
*Automatic, Self-Cleaning: Ensures uninterrupted operation with minimal operator intervention, reducing labor costs.
*Effective Dewatering: Produces drier solids cake, reducing waste volume and subsequent handling or disposal costs.

Applications

For high-precision separation in space-limited layouts, this unit provides flexible and reliable performance across various fields:
*Municipal: Applied as primary or fine screening in urban wastewater treatment facilities.
*Industrial: Offers efficient pretreatment for effluents from food processing, pulp and paper, textile, and chemical plants.
*Specialized Projects: Ideal for low-depth channels and fine screen apertures (1–6 mm), delivering high capture rates with low head loss.
