Jan 16, 2019 · A moist non-hygroscopic granular solid at 26°C is to be dried rom 20% initial moisture to 0.3% final moisture (wet basis) in a rotary dryer at a rate of 1500 kg/h. Hot air enters at 135°C with a humidity of 0.015

• ### (pdf) modelling and design of rotary dryers

Rotary dryers were more expensive to design than fluidized bed dryers. Operationally, however, it is the other way around due to the favored heat transfer achieved in rotary dryers

• ### rotary dryers - feeco international inc

Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum
