Rotary Drum Dryer – Industrial Drying Equipment
The Rotary Drum Dryer is a high-efficiency industrial drying equipment designed for processing sawdust, wood chips, straw, and other biomass materials. With a power range of 7.5–30 kW and capacity from 1 to 10 tons per hour, this dryer is widely used in sawdust briquetting, wood pellet fuel production, straw briquetting fuel, charcoal machinery, agriculture and animal husbandry engineering, and other industries. The rotary drum dryer offers high thermal efficiency, large processing capacity, and simple operation, making it an essential component in biomass fuel preparation lines and material processing facilities.
Product Features
-
High Drying Intensity – The material is highly dispersed in the air, and all particle surface areas are exposed for effective drying. This maximizes the contact between material and hot air, resulting in rapid and uniform moisture removal.
-
Short Drying Time – Due to the efficient heat and mass transfer design, the drying time is significantly reduced compared to conventional dryers, improving overall production efficiency.
-
Simple Structure – The dryer features a straightforward design, making it easy to install, operate, and maintain. The robust construction ensures long service life with minimal upkeep.
-
Large Processing Capacity & High Thermal Efficiency – The dryer handles large volumes of material with excellent thermal efficiency. When drying unbound water, the thermal efficiency can reach up to 60%, significantly reducing energy consumption and operating costs.
-
Versatile Applications – Widely used in sawdust briquetting, wood pellet fuel production, straw briquetting fuel, charcoal machinery, agriculture and animal husbandry engineering, and other biomass processing industries.
