Rotary dryer is a large-scale machine used to dry formed fertilizer
granules, and it is one of the key equipments in the fertilizer
industry. It is also suitable for drying materials such as slag,
clay, limestone, phosphogypsum, steel mill water slag, power plant
slime and sewage treatment plant sludge. The machine continuously
draws the heat from the hot blast stove at the head position to the
tail of the machine through the fan installed at the tail of the
machine. It makes the material fully contact with the hot air to
take away the moisture in it, so as to achieve the purpose of
uniform drying. It has the advantages of large drying capacity,
stable operation, low energy consumption, convenient operation and
high output.
