Redesigned all over, the Brabender BagMaster bulk bag discharger is now available for lined or unlined bulk bags up to 1.5 t. Its most outstanding feature is a novel discharge system. The bulk bag is centrically placed on a horizontal massage ring with a front gap, through which the bag or liner outlet is guided. As the outlet does not have to be lifted above the ring, headroom requirement is substantially reduced. The mas-sage ring is equipped with so-called massage rods around its circumference. For bag discharge the ring and thus the bottom of the bulk bag is set into a see-sowing movement by a pneumatic cylinder making the massage rods act on the lower bag sides and particularly on the bag corners, which can normally hardly be emptied. At the same time the see-sawing motion acts on the outlet itself, which is not affected at all by conventional designs. The agitation thus achieved results in mass flow inside the bag, uniform bulk ingredient discharge and complete emptying-out also of the bag corners even in case of poorly flowing ingredients.
