Rotary drum screen(trommel screen) can screen the following materials: black earth, compost, organic waste, green waste, wood waste (bark, sawdust, woodchips etc), domestic refuse, municipal waste, recycled asphalt, concrete, slag coal, sand, gravel, sone, clay, alluvial gold sand and many other materials.
How to work:
A trommel screens material by spinning a drum, usually with some kind of paddles or bars running inside the length of the tube to catch and lift the passing debris. Once picked up, gravity takes over and the debris falls back down, causing a break up of the material (as it tumbles).
This process is repeated until the debris is small enough to pass through the screen (fines) while the larger debris exits through the opposite end of the trommel drum. This produces two products, one of a finer soil and one of rocks, roots, wood waste, etc., which is referred to as rejects, overs, or trash.
