Rotary Drum Drying Machine,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.
* The operating parameter can be changed according to different materials, with high expandability.
* With special design, hot air furnace could generate clean hot air for the rotary dryer, which is environment friendly due to little dust and noise during working process.

How Sawdust Drying Machine to Work?
Sawdust dryer is composed of rotating cylinder, transmission device, supporting device and shoveling plates, etc. When the wet materials are fed into the rotating cylinder by the belt conveyor or bucket elevator, the hot air furnace supplies hot air to the rotary dryer. With the rotation of drum dryer, the shoveling plates inside the drum walls will fully mix the wet material and hot air, then the moisture will be evaporated by the high temperature of the hot air. Finally, the dried materials are discharged from the discharging hole for further pelletizing.

Wide Application of Sawdust Drying Machine
Sawdust drying machine has a strong adaptability of materials, it is suitable to dry biomass materials with high moisture content, such as sawdust, straw, alfalfa, wood shavings, bagasse, compound fertilizers, etc. Additionally, it also can dry non-biomass materials, like magnetic powder, lime, ores, coal, clay, etc. So, this drum drying machine is widely employed in biomass pellets industry, feed and fertilizer industry, chemical plant, construction.
