Features and benefits

 

1) Telescope-feed design, outer cylinder combined with inner cylinder.
2) Avoid the material pollution.
3) High efficiency, save energy.

 

The Indirect Heat Rotary Dryer provides high temperature radiant heat from the cylinder wall. Hot gas circulating between the exterior of the dryer shell and interior of the stationary firebox transfers heat through radiation and conduction to dry and process materials. Special flighting, designed for each application, moves material through the dryer while holding it against the shell, ensuring maximum exposure to radiant heat.
 
The Indirect Heat Dryer is the best choice for applications in which high temperatures and indirect heating are required. It is used consistently for drying materials that cannot be exposed to products of combustion and for drying materials that consist of fine particulate easily conveyed in a high velocity hot gas stream. These include carbon black, kaolin clay, alumina, boric acid, casein and sodium nitrate.
