Direct-Fired Dryers Custom Rotary Dryer Equipment

A Direct Fired Dryer. A direct fired dryer operates in one of two modes: co-current, or counter-current. In either of the above arrangements, the operation of a direct fired rotary dryer is based on the combustion system (burner) being directly coupled to the rotating shell. Therefore the combustion process (flame) occurs inside the rotating shell.

What is a Rotary Dryer and Who Uses It? Thompson

The flighting in a rotary drum dryer system can be changed to repurpose a used or existing dryer. A flighting designer can look at the flow characteristics of the material in question and determine what kind of flights are necessary, thereby converting the dryer to a new purpose at a fraction of the cost of buying a new dryer. Hopefully.
