Product Overview The Stationary Compost Trommel Screen is a fixed rotary screening unit for grading cured livestock manure compost and other organic materials. Installed downstream of composting and material handling equipment, it separates a fine fraction for further processing or use from oversized material that may require reprocessing. Its support frame, feed and discharge connections, access arrangements, and enclosure can be configured for a new facility or an existing organic fertilizer line.
Key Features
  • Continuous separation of screened compost and oversized particles.
  • Electric drive suited to integration with a fixed processing line.
  • Screen openings selected according to the required finished compost grade.
  • Configurable feed, collection, and discharge interfaces for conveyors or hoppers.
  • Optional enclosure and cleaning arrangements according to material and site conditions.
  • Maintenance access planned around the drum, drive, and wear components.
Structural Components Typical assemblies include a perforated rotary drum, supporting frame, drive and support system, feed inlet, fines collection area, oversize outlet, guarding, and electrical controls. Depending on the material and selected design, the drum may incorporate internal conveying flights or a screw profile. A brush or scraper can be specified where screen blinding is a concern.
Working Principle Cured compost enters the rotating drum from the feed end. Rotation lifts and turns the material, allowing particles smaller than the selected openings to pass through the screen into a collection hopper or conveyor. Larger pieces continue to the oversize outlet. Feed rate, drum configuration, and screen opening are selected together to suit the compost's moisture, particle size, and required separation.
Technical Specifications
  • Installation: Fixed installation on a project-designed support structure.
  • Screen opening and drum dimensions: Customizable according to the required product grade and throughput.
  • Drive power and electrical supply: According to project requirements.
  • Capacity: Available upon request after feedstock and operating conditions are confirmed.
  • Enclosure, conveyors, and controls: Customizable.
Applications Suitable for screening adequately cured pig manure compost, cattle manure compost, poultry litter compost, and blended organic fertilizer feedstock, subject to material testing. In commercial pig farm waste treatment projects, the screen can form part of a line connecting the composting area, conveyors, oversize return route, and finished product handling area.
Customization Options Available options may include alternative screen openings, replaceable screen sections, a drum cleaning brush, dust enclosure, maintenance platforms, and matched infeed and discharge conveyors. The steel support frame and installation layout can be designed around the available footprint, local climate, farm conditions, and adjacent steel structure building.
Installation & Maintenance Position the unit on an engineered foundation or support structure with clear access to the feed end, discharge points, drive, and drum. Coordinate the layout with upstream and downstream conveyors, power supply, guarding, and dust management. Routine maintenance includes checking screen openings for blockage, removing wrapped material, inspecting wear parts and supports, and servicing the drive according to the supplied equipment manual.
Product FAQ

Can it screen fresh manure?
The unit is primarily intended for material with suitable screening characteristics. Wet or sticky manure may blind the openings; feedstock condition should be evaluated before equipment selection.

How is the screen opening selected?
Selection depends on the target compost grade, feedstock particle distribution, moisture, and the intended use of the oversize fraction.

Can it be added to an existing composting line?
Yes, subject to a review of available space, support structure, electrical supply, and conveyor connection heights.
