AI Technical Summary
In existing rotary drum dryers, expanded graphite tends to fall to the bottom of the drying drum during the drying process, resulting in short contact time with hot air and low drying efficiency.
By employing agglomeration units and a spraying device, and utilizing an alternating arrangement of umbrella-shaped agglomeration plates and conical hoods, combined with a feeding pump and an air-source heat pump dryer, the graphite is circulated and sprayed, and its contact time with hot air is extended.
This improves the drying efficiency of expanded graphite, ensures full contact between graphite and hot air, and shortens the drying time.
