Rotating trommel screen is primarily used for sorting municipal solid waste after coarse crushing. As the material tumbles inside the rotating drum, particles smaller than the screen openings pass through, while larger materials are conveyed to the air separator. The trommel is installed at an incline of 5–8°. The screen openings are sized so that 90% of the screened material is smaller than 80mm. The trommel screen features minimal clogging and is easy to clean.
