dust emission is due to the kiln feed, while the other sources of dust emissions include the crushers, grinding clinker coolers and material handling equipments. The case study suggests ... form clinker, grinding the clinker with gypsum in cement mill and storage of cement in silo packing and distribution of cement.
A baghouse,also known as a baghouse filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air. Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use baghouses to control emission of air pollutants.
In the cement mill ESP, inlet dust load can exceed 700 g/Nm 3. Our ESP includes a pre-separator hopper to separate coarser dust and maximise overall efficiency. FL's coal mill ESP can be designed with a N 2 or CO 2 purging system. Explosion flaps can be added to the roof to meet ATEX/NFPA standards requirement for vent pressure clearance.
