The big bags unloading station SRB-1 consists of a frame, a conic receiving hopper with a rubber packing and a grid for lumps holdup, knives for big bags cutting and an unbalanced mass vibration generator. In the process of unloading at SRB-1 a big bag is held by a lift and transfer mechanism that’s why the unloading of different materials is performed sequentially. For parallel unloading of several big bags the unloading station SRB-2 is used, the structure of which includes an additional frame, adjustable for height and cross traverse, to which a big bag is fixed. The presence of a traverse allows using the lift and transferring mechanism for other operations after the big bag is fixed for unloading. The station SRB-4 has smaller dimensions and is recommended for usage in space-limited process plants. Big-bags unloading station SRB-5 is designed for uniform supply of bulk materials from big bag into storage bins or transport units. The material in the bags must be conditioned and it must satisfy specifications.
