This video introduces rotary dryers and their auxiliary equipment for pellet mill production lines based on on‑site footage. Let’s look at the drying process with a biomass heat source for your pellet mill. Biomass Burner:The burning of biomass pellets produces high‑temperature flames, providing a heat source for the entire drying system of the pellet mill.
Hot air furnace: The high‑temperature flame enters the hot air furnace for heat exchange. It is converted into clean high‑temperature hot air and then delivered into the rotary dryer.
Rotary dryer:High‑temperature hot air is sent into the rotary dryer drum. The wet material is continuously tumbled with the drum, making full contact with hot air for dehydration. Finally, the fan delivers system airflow. The cyclone separator removes dust and fines, and the airlock discharges dried material with air‑sealing. Heat source, dust‑removal and discharge accessories are universally applicable. Drying main units have various forms. Single‑drum and triple‑drum are common rotary dryer configurations, which we will introduce next.
Three‑layer nested sleeve structure;Sufficient heat exchange, high thermal efficiency, low energy consumption;Uniform drying, stable outlet moisture content;Suitable for high‑volume, high‑moisture materials.
Single‑drum structure for easy inspection and maintenance; Fewer parts, low maintenance costs; Lower initial equipment investment; Mostly applied for medium‑volume drying operations.
We can provide you with a complete drying‑pelleting system according to your raw material moisture content and production output.
