When it comes to drying solid bulk materials, Hengyang direct heat rotary drum dryer machines have been chosen for their rugged build, ultimate reliability and excellent ROI. Our direct heat rotary drum dryer machines rely on contact between the material and process gas to dehydrate a very broad variety of materials.
In the rotary drum dryer process, combusted gases mix with clean, heated air. The wet bulk material is propelled through the system via a hot gas air stream. The material is continuously lifted by the cylinder flights and showered through the concurrent stream of hot gases. The three full-length interlocked concentric cylinders rotate together to create the highest velocity possible in the inner-pass. As lighter particles quickly lose 60% of their moisture and move out of the cylinder, heavier/denser particles are retained until they also lose 60% of their moisture.
Known for our industrial innovation and engineering expertise, Hengyang is a worldwide leader in rotary drum dryer machine manufacturing, installation knowledge, drum dryer reconditioning services, and network of used drum dryers and portable rotary drum dryers rentals.
