A Drum Screen (also known as a rotary drum filter) is an essential mechanical filtration device used for the continuous and automatic removal of suspended solids, plastics, and organic fibers from wastewater. By utilizing a rotating cylindrical screen, the system separates fine debris that traditional bar screens might miss. As a professional drum screen manufacturer, Qingdao Yimei designs these units to act as the ultimate "gatekeeper" for industrial process water and municipal sewage, preventing downstream equipment clogging and optimizing overall treatment plant performance.
To accommodate different flow rates and particle sizes, we provide several specialized rotary screening technologies:
Internal Feed Drum Screens: Wastewater enters the center of the drum and filters outward, ideal for handling large volumes of water with high fiber content.
External Feed Drum Screens: The effluent is fed onto the outside of the rotating drum, a common choice for industrial process water recycling.
Micro-Hole Rotary Screens: Featuring precision-woven mesh for ultra-fine filtration (down to 20 microns), often used in tertiary treatment or membrane protection.
Gravity-Flow Drum Screens: A low-energy solution that utilizes hydraulic head pressure to pass water through the filter media.
Qingdao Yimei’s industrial drum screens are built with engineering precision to ensure long-term stability under 24/7 operating conditions:
Advanced Self-Cleaning Mechanism: Equipped with high-pressure internal spray bars, our screens automatically flush away trapped solids, ensuring a non-clogging surface and constant flow rate.
Premium Material Integrity: Constructed entirely from SUS304 or SUS316L stainless steel, our equipment offers exceptional resistance to chemical corrosion and abrasive wear, ensuring a long lifespan in harsh environments.
Low Operational Costs: Designed with high-torque, low-speed motors and VFD (Variable Frequency Drive) support, the system minimizes energy consumption while maximizing mechanical reliability.
Full Enclosure Design: Our units feature a fully sealed structure to prevent odor leakage and splashing, maintaining a clean and safe working environment for factory personnel.
Customizable Filter Media: Depending on your requirements, we offer wedge wire or perforated mesh configurations with apertures ranging from 0.2mm to 5mm.
Our industrial drum screens are widely deployed across sectors requiring high-efficiency solids recovery:
Pulp & Paper Industry: Essential for fiber recovery from white water, reducing raw material waste and lowering the COD load of discharge.
Slaughterhouses & Food Processing: Efficiently removing hair, feathers, and skin fragments that can easily foul pumps and biological reactors.
Textile & Dyeing: Intercepting fine lint and threads to prevent clogging in heat exchangers and advanced oxidation systems.
Plastic Recycling: Washing and filtering recycled plastics to remove contaminants and improve the quality of the final pelletized product.
When you source from Qingdao Yimei, you are investing in 30 years of engineering excellence and global logistics expertise.
Industrial-Scale Manufacturing: Operating out of a 36,000m² modern facility, we control every step from laser cutting to final assembly. This allow us to offer a highly competitive drum screen price without the markups of trading companies.
Rigorous QA/QC Standards: Every drum screen undergoes a 72-hour mechanical run-test and dynamic balance check to ensure vibration-free operation before it leaves our factory.
Global Project Footprint: With successful installations in over 120 countries, our engineers understand the specific environmental and regulatory requirements of different global markets.
Lifetime Technical Support: We provide a comprehensive spare parts kit and 24/7 multilingual support to ensure your pretreatment system never stops protecting your plant.
