Biomass Dryer for sawdust
Biomass Sawdust rotary dryer is applicable to the plant of straw press block fuel, charcoal machinery, sawdust pellet fuel, sawdust press block, farming and animal husbandry engineering etc. industry. Such as wood drying, wood chips drying, sawdust drying, corn straw drying, soybean straw drying, cotton straw drying, wheat straw drying, sorghum culm drying, ginkgo biloba drying, mulberry leaves drying etc. agricultural cellulose category etc, materials.
Working Principle
wet material is sent to the hopper by belt conveyor or bucket elevator, and then the feeder through the hopper enters the feeding port through the feeding pipe. The inclination of the feeding pipe should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. Rotary dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immindiately by lifter board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, moisture one the surface and inner of the material is dried by repeatedly scattering.

What is the working principle of drum dryer?
Rotary dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immindiately by lifter board when enters the shell from feeding tank and feeding chute. Because the drier is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, moisture one the surface and inner of the material is dried by repeatedly scattering.
Whick kind of material is suitable for drum dryer?
1. Powder & particle: Sands, limestone, stones, clay, mineral filter cake, coal, iron sulphate, filter cakes, fly ash, gypsum etc.
2. Damp and sticky material: Coal slime, sewage sludge, bentonite, Kaolin etc.
3. Corrosive material: Distillers grains, Fertilizer, animal dung, slag etc.
4. Biomass material: Sawdust, wood chips etc.
