Production Problems It Solves
A mixed bulk feed needing coarse and fine outlets
Smaller particles fall through the drum openings while retained pieces travel toward the end discharge.
Large irregular feed needing progressive exposure
Drum rotation turns the material and exposes fresh surfaces to the screen along its length.
Where It Fits in Your Plant
Compost and soil screening
Separate coarse pieces from finer material before further handling, using openings suited to the desired product. Moist fibrous feed can wrap or block apertures.
Sand and mineral preparation
Remove larger pieces from suitable bulk feed. A trommel separates by size, not by composition, so stones and other contaminants of accepted size can remain in the product.
How the Drum Trommel Screen Works
Rotation lifts and redistributes the feed. Suitable particles pass through the drum wall while oversize advances to the end. Incline, rotation and internal features affect travel and residence time.
Selection Factors
- Screen zones: opening size and active drum length define where each fraction separates.
- Residence time: rotation, inclination and internal features affect how long the feed remains in the drum.
- Feed condition: moisture, wrapping fibres and sticky deposits can obstruct the openings.

Common Issues & Checks
- Low screening recovery: inspect blinded openings and uneven feed before increasing rotation speed.
- Material wrapping or buildup: isolate the drum before cleaning and inspect the affected screen sections.
