Achieve Superior Purity with Our Rotary Drum Sieve

Our Drum Sieve Machine is expertly designed to remove coarse impurities such as straw, strings, paper, wood chips, stones, and clumps from your primary material. By integrating our rotary sieve at the intake point of your processing line, you can protect downstream machinery from damage, reduce wear and tear, and ensure a cleaner, higher-quality final product.

Key Features & Benefits

• Robust & Durable Construction:Built with high-grade Mild Steel (MS) or Stainless Steel (SS304/SS316) for longevity and resistance to corrosion and abrasion.
• High Separation Efficiency:The rotating drum design, combined with an optimized incline angle and customizable screen perforations, ensures over 99% cleaning efficiency.
• Low Power Consumption:Engineered for maximum output with minimal energy usage, reducing your operational costs.
• Automated Cleaning Mechanism:Equipped with an external brush that continuously cleans the screen mesh, preventing blockages and ensuring consistent performance.
• Dust-Free Operation:An integrated aspiration hood with a regulating valve effectively removes dust and light impurities, maintaining a clean and safe working environment.
• Easy Maintenance & Screen Replacement:The user-friendly design allows for quick and easy access to the drum for cleaning and fast replacement of sieve screens, minimizing downtime.
• Customizable Capacities & Sizes:We offer a range of models and can customize the machine’s capacity, drum size, and mesh perforation to perfectly match your specific requirements.

How Our Drum Sieve Machine Works

The working principle is simple yet highly effective:

1. Material Inlet:Raw material is fed into the machine through a guided inlet chute.
2. Rotating Drum:The material enters a slowly rotating, inclined cylindrical drum. The drum’s wall is a screen made of perforated metal or wire mesh.
3. Sieving & Separation:As the drum rotates, the desired-sized material falls through the screen’s perforations into a collection hopper below.
4. Impurity Discharge:Coarser, oversized impurities that cannot pass through the screen are carried by the rotational movement along the drum and are discharged at the opposite end.
5. Aspiration:Simultaneously, an optional aspiration system pulls away light particles and dust for a comprehensively clean output.

Versatile Applications Across Industries

Our rotary trommel screens are indispensable in a multitude of sectors:

• Agriculture & Food Processing:Perfect for pre-cleaning wheat, maize (corn), rice, seeds, spices, pulses, and other grains in flour mills and food processing plants.
• Waste Management & Recycling:An essential machine in Municipal Solid Waste (MSW) processing facilities for separating compost, soil, gravel, and other organic and inorganic materials. Ideal as a compost sieving machine or vermicompost sifter.
• Mining & Aggregates:Efficiently grades sand, gravel, soil, and various minerals based on particle size.
• Chemical & Pharmaceutical:Used for scalping and separating powders, granules, and other chemical compounds.
• Wood Industry:Separates wood chips, sawdust, and other wood by-products.

Frequently Asked Questions (FAQ)

Q: What is the main difference between a drum sieve and a vibratory sieve? A: A drum sieve uses a rotating cylindrical screen, ideal for high-capacity pre-cleaning and separating materials with large size differences. A vibratory sieve uses vibration to separate finer particles and is often used for more precise grading.

Q: Can I use this machine for wet or sticky materials? A: Yes, the rotary action and the auto-cleaning brush make our drum sieve effective for materials with some moisture content, like compost. For very sticky materials, we can offer further customizations.

Q: How do I choose the correct screen mesh size? A: The ideal mesh size depends on your material and the size of the impurities you want to remove. Our technical team will consult with you to recommend the perfect perforation size for your application.

Q: What is the typical lead time for a machine? A: Lead time varies based on the model and customization. Please contact us for a precise delivery schedule.
