    Examples include installations with 2-fan kiln systems, in cement mills or on separators. In such cases, there is a need for efficient dust pre-separation to reduce the dust burden reaching the bags. A wide central hopper is used to decrease the axial gas velocity so that a dust pre-dropping action takes place
