Handling the Pellet Plant dust
Introduction:
Clair has successfully supplied 10 de-dusting systems for Pellet Plant application for a reputed client in Maharashtra. The project included design, engineering, manufacture, supply and commissioning of the de-dusting systems. The complete package includes 10 de-dusting systems with bag filter volumes ranging from 2,000 m3/h to 43,600 m3/h.
The de-dusting system provided is for handling materials such as iron ore fines, limestone, dolomite, coke and bentonite. The iron ore fines are received on reversible conveyor at top of day bins in the pellet plant section. This reversible conveyor will feed to two parallel reversible shuttle conveyors over two bays of day bins. Eight numbers of bins with effective volume of 500 m3 is installed for storage of iron ore fines. Dust generated during this operation is captured in the de-dusting system.
Coarse additives like limestone, dolomite, coke & bentonite are received at one common ground storage unit inside the pellet plant by truck. The individual raw additive is fed by pay loaders onto one outgoing conveyor through over-ground hoppers and vibrating feeders as per requirement and transported to respective bins in coarse additive storage bins unit. Coarse additives are stored in separate bins, two numbers each for limestone, dolomite, coke & bentonite. The effective volume of each bin is approximately 200 m3. The dust generated from these processes are captured and filtered out in the bag filters. The de-dusting systems offered by Clair to guaranteed to achieve an outlet emission of ≤ 10 mg/Nm3.
