What Is a Rotary Drum Screen?
A rotary drum screen is a continuous mechanical screening device used to separate solids from liquids. Process water or slurry passes through a rotating cylindrical screening surface while larger particles are retained and transported toward the solids discharge area.
GXFilter manufactures wedge wire rotary drum screens using V-shaped profile wire and welded support rods. The continuous-slot screening surface can be customized according to the required separation size, flow conditions, material, drum dimensions and installation requirements.
Rotary drum screens are used for wastewater screening, industrial solid-liquid separation, food processing, pulp and paper, sugar processing and other industrial applications.
Why Choose a Wedge Wire Rotary Drum Screen?
Continuous Slot Opening
The V-shaped wedge wire profile creates continuous slot openings that provide controlled particle separation and efficient liquid passage.
High Effective Open Area
The wedge wire screening surface can provide a large effective open area for efficient liquid flow while maintaining the required screening opening.
Custom Slot Sizes
Slot openings can be manufactured according to the required particle separation size and process conditions.
Rigid Welded Construction
Resistance-welded profile wire and support rods create a strong cylindrical screening structure for industrial applications.
Our wedge wire rotary drum screen is designed for efficient and continuous screening processes. Manufactured using precision resistance-welded wedge wire profiles, it provides high open area, excellent strength, and long service life.
Widely used in water and wastewater treatment, pulp and paper, mining, food processing, and chemical industries, this rotary drum screen ensures stable performance with minimal maintenance.

Wedge Wire Rotary Drum Screen Construction
GXFilter rotary drum screens are manufactured from a continuous wedge wire screening surface supported by welded rods and structural components.
The cylindrical screen can be manufactured according to the required drum diameter, drum length, slot opening, material and mechanical connection requirements.
Typical Construction Components
- V-shaped profile wire
- Longitudinal support rods
- Continuous slot openings
- Resistance-welded screen cylinder
- Structural end rings
- Flanges or customized connections
- Custom mounting components
The rotary drum screen operates by rotating a cylindrical wedge wire drum partially submerged in the process flow. Liquid passes through the continuous slots while solids are retained on the surface and discharged by gravity or spray-assisted cleaning.
This design allows continuous operation with reduced clogging and minimal downtime.
How Does a Rotary Drum Screen Work?
Step 1 — Feed
Process water or slurry enters the rotary drum screening system.
Step 2 — Screening
Liquid passes through the wedge wire slots while larger solids are retained on the screening surface.
Step 3 — Rotation
The drum rotates continuously to move retained solids toward the discharge area.
Step 4 — Solids Discharge
Separated solids are continuously discharged for collection, treatment or downstream processing.
How to Select the Right Rotary Drum Screen
Selecting a rotary drum screen requires more than choosing a drum diameter. The screening surface and drum configuration should be designed according to process capacity, solids characteristics, separation requirements and installation conditions.
1. Determine the Required Flow Rate
Provide the normal and peak flow rate of the application. The required screening area and drum dimensions should be selected according to the actual process capacity.
2. Define the Required Slot Opening
The slot opening determines the approximate particle separation size. GXFilter can manufacture wedge wire screening surfaces with customized slot openings according to the application.
3. Select the Screen Material
SS304 is commonly used for general industrial applications. SS316 and SS316L can be considered for applications requiring higher corrosion resistance.
4. Determine Drum Diameter and Length
Drum diameter and length depend on required screening area, flow conditions, solids loading, installation space and mechanical design.
5. Confirm the Flow Configuration
The required flow direction and feed configuration should be considered during the rotary drum screen design process.
6. Provide Process Information
For a custom rotary drum screen, provide flow rate, liquid characteristics, solids size, solids concentration, required slot opening, material and installation requirements.

Frequently Asked Questions
FAQ 1: What is a Rotary Drum Screen?
A Rotary Drum Screen is a continuous mechanical screening system used to separate solids from liquids. It typically consists of a cylindrical wedge wire screen drum, rotating drive system, inlet and outlet sections, and a cleaning or scraping mechanism. As wastewater or process liquid passes through the rotating drum, solids are retained on the screen surface and discharged continuously. Rotary drum screens are widely used in wastewater treatment, industrial filtration, food processing, mining, pulp and paper, and other solid-liquid separation applications.
FAQ 2: How do I choose the right Rotary Drum Screen?
The correct Rotary Drum Screen depends on several operating parameters, including flow rate, liquid characteristics, solids size, required slot opening, screen diameter, drum length, material, and flow direction. For example, stainless steel wedge wire screens are commonly selected for applications requiring corrosion resistance and precise particle separation. GXFilter can customize the wedge wire slot size, drum diameter, length, support structure, and stainless steel grade according to the application and equipment requirements.
FAQ 3: What is the difference between a Rotary Drum Screen and a Static Screen?
A Rotary Drum Screen uses a continuously rotating cylindrical screen to separate and discharge solids, while a Static Screen uses a stationary curved or inclined wedge wire panel. Rotary drum screens are suitable for continuous screening with automatic solids removal and can handle applications where continuous operation and higher screening capacity are required. Static screens have a simpler structure and are often selected for applications where low maintenance and a compact installation are preferred.
FAQ4:Can GXFilter manufacture a custom rotary drum screen?
Yes. GXFilter manufactures custom wedge wire rotary drum screens according to customer drawings or application requirements. Customers can specify drum diameter, drum length, slot opening, material, profile wire, support configuration and other mechanical requirements.
