Trommel Screen (Rotary Drum Screening Machine)
A trommel screen separates materials by size using a rotating perforated drum. It is a proven front-end sizing solution for MSW sorting, recycling, compost screening, soil, and mineral applications, helping reduce contamination and protect downstream equipment.
- Customized drum diameter, drum length, and hole size for project-specific cut points.
- Heavy-duty structure for continuous screening duty in recycling and waste sorting plants.
- Easy maintenance access and practical integration with conveyors, separators, and sorting lines.
Equipment Overview
Reliable Front-End Size Separation
The trommel uses a rotating perforated drum to split mixed material into oversize and undersize fractions. This simplifies downstream sorting, reduces contamination, and improves the overall efficiency of recovery lines.
Why Choose Our Trommel Screen?
Designed for stable sizing performance, reliable uptime, and practical integration into complete recycling and waste sorting systems.
Effective Size Separation
Separates fines and oversize consistently to stabilize downstream sorting and reduce carry-over contamination.
Flexible Screen Configurations
Custom hole sizes, screen panels, and lifters can be selected for wet, sticky, or mixed material streams.
Maintenance-Friendly Design
Access covers and wear-part options simplify inspections, reduce downtime, and keep service practical.
Rugged Industrial Build
Engineered for continuous screening duty with reliable drive components and stable support structure.
Energy-Efficient Screening
A simple rotary screening principle delivers reliable sizing with low mechanical complexity.
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.
Feed
Material enters the drum through a hopper or conveyor-fed inlet.
Lift and Tumble
Internal lifters cascade the material for better exposure to the screen openings.
Screen
Undersize passes through the perforations while oversize continues along the drum.
Discharge
Separated fractions exit to dedicated conveyors, chutes, or collection points.

Frequently Asked Questions
What is a trommel screen used for?
A trommel screen separates mixed material streams into different size fractions using a rotating perforated drum. It is commonly 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 more difficult materials, cleaning brushes, optimized lifters, and maintenance access can be added.
Can you customize the trommel for our site layout?
Yes. Feeding, discharge chutes or conveyors, drum length, supports, and maintenance access can all be customized to suit site layout and integration requirements.
What information do you need to size the machine?
Please provide your feed material type, moisture level, target cut size, required throughput, and any constraints such as mobility, footprint, and discharge direction.
Do you provide installation and after-sales support?
Yes. We support installation guidance, commissioning, spare parts, and maintenance recommendations to keep the trommel screen operating reliably.
