The capacity of the trommel screen The capacity of the trommel screen is closely related to the screen size. If you choose a 2 mm sieve, the output is 12-35 m³/h (19.2-56 t/h); its output can reach 175 m³/h (280 t/h) with a larger sieve (30 mm), which can meet the requirements of large-scale production. How does a trommel screen work?

TROMMEL SCREENS. How Do Trommels Work ? Material feeds into the drum, is lifted up by the rotation and aerated as it falls back down. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum.
