Rotary Dryer Drum Dryer

Introduction :

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 immediately 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.

Feature :

1. Rotary Dryer is mainly used for drying biomass or Fertilizer or animal feed powder materials , it has rotary drum and can dry high humidity materials, such as sawdust, straw, stalk, animal feed materials from maize, soybean,cereal fertilizer materials from poultry manure , home or factory waste etc .
2. Rotary drum dryer drum RPM can be controlled according to raw materials humidity. If humidity is large, then can control feeding speed lower and drum RPM lower to make longer drying time.

3. Rotary Dryer has temperature adjusting equipment between stove and dryer, which can adjust hot air temperature when feeding to dryer drum according to raw materials humidity and outlet stove hot temperature.

4. Rotary Dryer has two ways to discharge materials, one is to outlet from rotary drum bottom, it is mainly fit for large weight ratio materials , the other is to outlet materials from cyclone bottom , which mainly fits for light materials . so please tell us what kind of raw materials and dimension, raw humidity, then we will help you choose best dryer model.

5. There are multi-angle lifting style lifting plate inside of dryer; during drying, the lifting plate will raising the material evenly, which can ensure the material complete heating change with the hot air enough and also ensure the drying efficiency is good.
