What is a Trommel Screen & How Does it Work? | EZ-Screen

A trommel is a screen curved into a cylinder. The machine spins the cylindrical screen to sort through the material as you feed it through. During this process, the wet material tumbles around. Air gets added, and the soil, mulch, or sand becomes lighter and drier. The tumbling action also allows maximum contact time with the screen so that the ...

Trommel screen - Wikipedia

Some of the main governing equations for a trommel screen include the screening rate, screening efficiency and residence time of particles in the screen. These equations could be applied in the rough calculation done in initial phases of a design process. However, design is largely based on heuristics.
