Bagasse stockpile characteristics .
Construction
The geometry of bagasse stockpiles has centred on-two types. Large rectangular stockpiles vary widely in plan area and range in height from 3 to 9 m. The
largest. stockpile measures 75 m X 25 m X 6 n1 high. Elongated stockpiles of
triangular cross-section have been preferred for ease of assembly and weatherproof covering to prevent water ingress. Bagasse storage occurs outdoors on
ground which is generally well+drained. The exterior surface of an uncovered
bagasse stockpile forms a relatively impermeable skin, up to 30 mm thick, of
matted bagasse fibres and microorganisms. The skin can serve as an effective
water shield in average rainfall conditions. The total effectiveness of weather protection for an uncovered stockpile depends on the provision of good runoff
drainage at the base of the stockpile and the maintenance of a convex geometry
over the whole of the stockpile surface. Packing density of bagasse stockpiles
depends on the loading technique. Loosely packed storage ranges between
100-150 kg/m (50 per cent moisture basis). Where mechanical compaction
occurs during the loading process, the density increases to 180-250 kg/m
