Screening drums separate the material input in different grain sizes. The specific materials, throughput rates and the screen size of the output fractions are main criteria for the appropriate size of the screen drum. One to four screen steps are feasible.
The exchangeable screen sheet metals have round or rectangular holes, as well as an additional entangling protection if required for a particular material. Further bag ripping tools, accelerators, mixers or other means can be added for further improvement of the screening result.
The rugged steel body of the drum with mechanically worked raceways is propelled by heavy duty impellers. The housing of the drum screen is a rugged steel construction with large maintenance flaps and doors. Closed transfer chutes minimise the dust exposure. The steel sub-structure can be laid out according to on-site requirements.
