A trommel screen separates materials by size using a rotating drum. It filters fine material through screen holes while larger particles roll out the end. Trommel screens are widely used in recycling, composting, and quarrying to cleanly divide material for reuse or disposal.

Trommel screens are used for screening compost, topsoil, mulch, sand, gravel, and demolition waste. The rotating drum makes them especially effective for wet, sticky, or organic material. They’re commonly found in recycling plants, landscaping, and soil processing operations.

A trommel screen works by feeding material into a rotating, cylindrical drum with holes. As the drum spins, finer material falls through the holes, while larger pieces continue to move through to the end. This motion ensures clean separation without aggressive shaking.

Trommel screens rotate material inside a drum, which suits wet or clumpy loads. Deck screeners vibrate material over flat screens and are best for dry, granular loads. Trommel screens are slower but more effective with compost, soil, and mixed debris.

Yes. One of the biggest advantages of trommel screens is their ability to handle wet or sticky materials. They screen moist compost, mulch, or soil without clogging, making them ideal for weather-affected sites or organic waste handling.

CRS NI designs and manufactures high-performance trommel screens for a wide range of recycling and waste applications. Our trommels are built to handle demanding materials including Construction & Demolition (C&D) waste, Commercial & Industrial (C&I) recycling, Mixed Dry Recyclables (MDR), WEEE (Waste Electrical and Electronic Equipment), and gypsum.

Trommel screen output depends on drum size and material type. CRS NI’s heavy-duty trommels are built for high-volume performance. Our stationary trommel systems can handle up to 160 cubic metres per hour, depending on the material type and screen configuration.

Choosing the right trommel screen depends on your throughput, material type, and mobility needs. Compact models suit contractors and small yards. Larger trommels are best for high-volume screening, composting sites, or aggregate operations that demand heavy-duty output.

No. Trommel screens have fewer moving parts than deck screeners, which means less wear and simpler maintenance. Regular cleaning, inspecting brushes and screens, and tension checks are enough to keep your machine performing at full capacity.
