The drying intensity is high, and due to the high dispersion of the material in the airflow, the entire surface of the particles is actively the effective area for drying. Short drying time. The airflow dryer has a simple structure, small footprint, and is easy to build and maintain. Large processing capacity and high thermal efficiency. The dryer has achieved "zero horizontal thrust", greatly reducing the wear of the blocking wheel and ensuring smooth and reliable operation of the cylinder; The dryer adopts a self-aligning roller device, which ensures that the fit between the roller and the roller is always in linear contact, greatly reducing wear and power loss.
