Trommel Screen (Rotary Drum Screening Machine)
A trommel screen (also called a rotary drum screen) separates materials by size using a rotating perforated drum. It’s a proven front-end sizing step for MSW sorting, recycling, compost, soil, and mineral processing—reducing contamination and protecting downstream equipment.
Why Choose Our Trommel Screen?
Designed for stable sizing performance, reliable uptime, and easy integration into complete sorting and recycling lines.
Effective Size Separation
Consistently separates fines and oversize to stabilize downstream sorting and reduce contamination.
Flexible Screen Configurations
Custom hole sizes, screen panels, and lifters to match wet, sticky, or mixed material streams.
Maintenance-Friendly Design
Access covers and wear-part options help speed up inspections and reduce downtime.
Rugged Industrial Build
Engineered for continuous operation with reliable drive components and stable support structure.
Energy-Efficient Screening
Simple, proven screening principle with a low-complexity, high-value mechanical design.
Easy Line Integration
Works with conveyors, bag openers, air separators, magnets, and optical sorting systems.
How a Trommel Screen Works
Material tumbles through a rotating drum; fines pass through the holes and oversize exits at the discharge end.
Material enters the drum via hopper or conveyor.
Lifters cascade the stream for better exposure to screen openings.
Undersize passes through; oversize continues along the drum.
Separated fractions exit to dedicated conveyors or chutes.
Key Components & Options
Configure the drum, screen panels, and discharge layout to fit your site constraints and material characteristics.

Common Applications
A trommel screen is a versatile classifier for mixed streams where reliable pre-sizing improves the whole line.
- Municipal Solid Waste (MSW) & MRF pre-sorting
- Compost and organic fraction screening
- Soil and aggregate sizing
- Construction & demolition (C&D) fines separation
- Recycling lines for mixed recyclables
- Mineral and ore screening (light to medium duty)

Frequently Asked Questions
What is a trommel screen used for?
A trommel screen is used to separate a mixed material stream into different size fractions using a rotating perforated drum. It’s widely used in MSW processing, recycling, compost screening, and aggregate sizing.
How do you prevent blinding with wet or sticky material?
We select suitable hole patterns, lifter designs, drum speed, and screen panel types based on moisture and contamination. For challenging materials, we can add cleaning brushes, optimized lifters, and access for regular cleaning.
Can you customize the trommel for our site layout?
Yes. We customize feeding, discharge chutes/conveyors, drum length, supports, and maintenance access. Share your layout and we can propose a configuration that fits your space and integration requirements.
What information do you need to size the machine?
Please provide your feed material type, moisture level, target cut size (hole size), required throughput, and any constraints such as mobility, footprint, and discharge directions.
Do you provide installation and after-sales support?
Yes. We can support installation guidance, commissioning, spare parts, and maintenance recommendations to keep your trommel running reliably.
