Rotary Trommels | McLanahan

How Rotary Trommels Work. As the cylindrical drum of a Rotary Trommel Screen rotates, raw feed material is lifted on shelves until it nears the top of the drum. Material then falls, tumbling onto other material at the bottom of the drum. This action helps to break down softer fractions, as well as separate different types of materials.MBR Screening Selection Criteria,the screen but are in the range of 1.3 to 2.5 (see also Table 1). This factor accounts for the blinding of the screen but cannot be compared with the % blinded area typically used for inclined screen applications.
