What is a Trommel Screen in MSW Management?
A trommel screen for municipal solid waste is a rotating cylindrical screening machine used to separate waste based on size.
It helps in dividing waste into:
- Organic (biodegradable) waste
- Recyclable materials (plastic, metal, glass)
- Reject waste
This process is essential for modern waste processing plants in India.

Working Principle of Trommel Screens
A trommel screen consists of a rotating cylindrical drum inclined at a slight angle (typically 3°–5°). The drum is perforated with holes of specific sizes depending on the required separation.
Material is fed into the higher end of the drum. As the drum rotates:
- Finer particles pass through the screen apertures.
- Larger particles move forward due to gravity and rotational motion.
- Internal lifters enhance material agitation and exposure to the screening surface.
The separation process is continuous and gravity-assisted, ensuring steady throughput.
Design Parameters of Trommel Screens
1. Drum Dimensions
- Diameter (D): Typically ranges from 1 m to 3 m
- Length (L): Usually 3 m to 12 m
- A higher L/D ratio improves screening efficiency by increasing residence time.
2. Screen Aperture Size
- Defines the cut size of separation
- Can vary along the drum length in multi-fraction designs
3. Rotational Speed
- Operates at 12-15 rpm
4. Inclination Angle
- Typically between 3° and 5°
- Affects material flow rate and retention time
5. Screening Area
- Effective area determines throughput capacity
- Calculated based on drum circumference and length
Capacity of Trommel Screens
General Capacity Range
- Small units: 5–30 TPH
- Medium units: 30–100 TPH
- Large industrial units: 100–500+ TPH
Factors Affecting Capacity
- Feed gradation and particle size distribution
- Moisture content and material stickiness
- Screen open area percentage
- Rotational speed and inclination
- Uniformity of feed
Types of Trommel Screens
1. Single Fraction Trommel
- One screen size
- Produces fine and oversize fractions
2. Multi-Fraction Trommel
