Dongding rotary dryers are offered mainly direct heat rotary dryers. These designs are readily adaptable to a wide variety of processing applications and are offered as stand-alone units or as part of complete thermal processing systems.

Dongding Directly Heated Rotary Dryers

The direct heat dryer design consists principally of an inclined rotating cylinder with internal flighting. This type of design brings process material into direct contact with the drying medium, either in a concurrent or countercurrent flow configuration. The drying medium may be products of combustion tempered with air, heated clean air. Direct heat rotary dryers are most appropriate when product characteristics reflecting particle size range, specific gravity, and shape permit reasonable drying air velocities through the cylinder, as well as for applications involving product temperatures upwards to 930°F (500°C).

Typical Materials Processed in Direct Rotary Dryers:

Alumina , Ammonium Nitrate, Ammonium Phosphate,  Granulated Fertilizers,  Urea, Food Products, Titanium Dioxide, Proppants, Sand, Clay, Metal Scrap, Pigments, Coal, Coal slime, Industrial slag and sludge, Biomass etc.
