FSM - Drum Screen The FSM drum screen can be used either as a screening unit, or to separate trash in a road sweepings installation or as a pre-separator in a grit wash separator. The dimensions of the screening unit depend on the throughput and the composition of the screenings. The FSM drum screen combines high performance with low maintenance costs. Functional principal The drum screen can be charged via feed pipe, free flow supply or screw conveyor. Material which does not pass through the perforations remains in the screening drum in accordance with hole size. A line of nozzles assists separation of small matter from large matter and washes off e.g. adhering grit. Washed off matter flows through the perforations with the wash water and passes to a collection tank from which it can be fed to a further treatment stage. If desired by customer, the screening drum can be provided with a series of perforations of differing sizes. This enables various fractions with different grain sizes to be obtained.
