If we understand how dry particles inside the equipment movement can better understand how drying equipment drying materials.
First of all, is used to dry heat flows from the bottom of drum direction into the drum inside, along a straight line along the wall with the rotation of the drum rotation to rise. When up to contact with materials will be heated for the material, because the material before they encounter the heat flow due to the rotation of the rotor blades was crushed, so when a stream of shredded material, after the material heating can also drive the material at the same time, makes the material being blown, don't stick together, heating area is larger, more likely to be dry.
Then, the heat flow with the water moisture from the air outlet of the exhaust out, new heat ?
