Drying is an very important step in making pellets process, because too high or too low moisture content of raw materials will affect the final quality of pellets. So before pelletizing, an appropriate drying machine is needed to reduce or minimize the moisture content of the materials. There are mainly two types of dryers, one is rotary sawdust dryer, the other is airflow dryer. The former is for the big processing capacity, the latter is for small quantity biomass sawdust.
Rotary Drum Drying Machine Performance Features
* Highly mechanized, high throughput, continuous running and high thermal efficiency.
* Reasonable structure design, simple operation and maintenance, economic space occupation.
* The drum dryer can reduces the moisture to 8%-12%, with the production ratio being higher 10%-15%.
* Inlet steam pipe is sealed by the advanced swivel joint, avoiding steam leakage, which greatly improves the drying efficiency.
