The design of Dingli Machinery Triple Pass Rotary Dryer is new technology developed by our technical team according to the past actual drying experience, and this new technology has been used more than 4 years successfully.

Right now in other China factories, you would can not see such new design of rotary dryer machine where they mainly produce the traditional single drum, double drum and triple drum rotary dryer machine with old technology.
