The Trommel Screen , also known as rotary screen,compost sieve or drum screen, is an  essential unit which is used mainly in the mineral and solid waste processing industries. It consists of a motor, reduction unit, cylindrical drum, screen frame and sealing cover, which is  normally elevated at an angle at the feed end. Physical size separation is achieved as the  feed material spirals down the rotating drum, where the undersized material smaller than the screen apertures passes through the screen, while the oversized material exits at the other end of the drum.

Trommel screen can be used in a variety of applications such as classification of solid waste  and recovery of valuable minerals from raw materials. Trommels come in many designs such as concentric screens, series or parallel arrangement and each component has a few configurations. However depending on the application required, trommels have several advantages and limitations over other screening processes.
