Tarmac's thermal rotary dryers are designed to be very robust compared to other drying methods like fluidized bed dryers, vertical fluidized dryers, vertical tray dryers, spray dryers or flash dryers. Six dryer diameters give Tarmac a wide range of drying ability from 10 to 400 tons per hour. What can be dried in Tarmac Rotary Dryers?
Indirect rotary dryers differ from convective-direct dryers in that heat is transferred to the wet product by conduction and radiation through the cylinder wall or through a series of tubes located circumferentially to the cylinder. Indirect rotary dryers use as heating medium hot gases coming from a combustion chamber.
