What Is a Trommel Screen?
A trommel screen is a rotating drum screener designed to separate material by size as it moves through the machine.
It’s one of the most effective ways to process:
- Compost
- Topsoil
- Mulch
- Wet or sticky material
👉 Especially when traditional screens start to plug up.
As the drum spins:
- Finer material falls through the screen openings
- Larger material continues through the drum
What Can You Screen with a Trommel?
If your material is wet, sticky, or inconsistent… a trommel is often the right solution.
Built for the materials that slow everything else down
Common applications include:
- Compost – Efficient separation of organic material
- Topsoil – Clean, consistent finished product
- Mulch – Removes oversize material quickly
- Wood waste – Handles stringy, irregular feed
- Dirt and soil – Ideal for landscaping and site prep
- Recycling & waste – Separates mixed material streams
Here’s why a trommel doesn’t plug up like everything else
If you’ve ever fought plugging, blinding, or material building up inside your screen…
The result: consistent throughput, even in difficult conditions.
🔄 Continuous Movement
Material is constantly rolling through the drum instead of sitting and packing in one spot
🧼 Self-Cleaning Action
Material lifts and drops as the drum rotates, breaking apart clumps and preventing buildup
➡️ Controlled Material Flow
Material moves at a steady pace, reducing surges and blockages

Reliable Trommel Screening Performance and Operating Efficiency.
Komptech heavy-duty trommels are efficient screening solutions engineered for soil, aggregate, mulch, waste and compost processing.
The solid punch plate horizontal drum is built to handle the toughest materials while delivering the highest quality output.
Machines in this range include:
- Nemus 2700 99 H.P. Up to: 230 yd³ per hour
- Primus 70 H.P. Up to: 90 yd³ per hour
Inside Look: The Genius Behind Komptech’s Spiral Design!
Komptech trommel screens use a spiral-shaped guide or helix inside the drum to help move material efficiently through the screening process. This design is an important feature for ensuring consistent throughput and maximizing screening performance.
Improved Screen Efficiency
Spiral Guide System – Unlike standard trommels, Komptech screens use a built-in spiral system inside the drum that actively moves material forward, preventing build-up and increasing efficiency.
How It Works
- The trommel drum is a large rotating cylinder with perforations (holes) that allow finer materials to pass through while larger materials continue moving through the drum.
- Inside the drum, a spiral-shaped guide (also called a helical baffle or spiral fins) helps direct and control material flow.
- As the drum rotates, the spiral structure gently pushes material forward, preventing it from just tumbling in place.
- This controlled movement ensures that materials spend the right amount of time inside the drum for proper screening.
Why It’s Important
- Prevents clogging & uneven flow: Without the spiral, material could accumulate in one spot, leading to inefficiencies.
- Ensures consistent screening: Material moves steadily through the drum, allowing for uniform separation.
- Increases efficiency: By guiding material through at a steady pace, the trommel achieves higher throughput.
- Enhances screening accuracy: Finer material gets screened effectively while larger pieces continue through.
How It Benefits Users
- Helps process more material in less time.
- Reduces maintenance by minimizing material buildup.
- Works well with a variety of materials, including soil, compost, wood waste, and aggregates.
Why Settle for Slow, Clogged-Up Screens?
Your operation moves fast—shouldn’t your trommel screen keep up? If you’re tired of slow material flow, constant blockages, and inefficient separation, you’re using the wrong screen. Komptech trommels are built to screen faster, cleaner, and more efficiently, making your job easier while boosting your bottom line.
