Trommel screen (trommel sieve) is a device designed for mechanical segregation of municipal waste according to its type (fraction). Trommel screen is spatial, cylinder-shaped steel construction covered with perforated sheet metal. The cylinder carrying raceways are placed on support rollers and are the transmission element of drive. The whole device is equipped with isolated frame which reduces the noise level, as well as odor and dust emissivity.
SIGMA S.A. offers sieves enabling to segregate (separate) three fractions of waste.
