Blending silo with a diameter of 14 m, silo height 45 m, silo capacity 4000 m3
The silos are operated in a continuous flow-through mode, also serving the purpose of raw meal storage. Feeding of the central cone blending silo is carried out via a parallel distributor which distributes fluidized raw meal evenly over the entire silo crosssection. The blending process takes place during the discharge operation.
During the discharge process, the flow-control gates are activated in combination with the adjacent aeration section. A programmed controller will start the operation in an alternating mode. During the discharge process, a funnel flow is created, the layer structure is broken up and an active material exchange takes place resulting in material blending.
The central bin is used to collect the different material flows. The design of the roller opening is directly connected to the linear function of the flow control gate. This flow can be controlled via belt.
