Overview of biomass rotary dryer

Rotary dryers are used to dry small, powdery or granular wet materials such as wood chips, sawdust, sand, mineral dust, agricultural waste, etc.

The raw material is transported by the scraper conveyor to the inside of the rotary dryer.and the front is equipped with a hot blast stove. The generated hot air enters the dryer by the fire separating device, and the material is dispersed by the low-speed rotation and bending plate.so that the high-temperature airflow passes through the material and make heat exchange, the rotary dryer has a certain angle of inclination, and sufficient air volume to drive the material forward.Finally, the dried material is discharged from the discharge port.

Features of biomass rotary dryer

1.Temperature measurement sensors and digital display instruments are installed at the high and low-temperature pipelines of the drying system to achieve the best drying effect and ensure the safe operation of the system.

2. It can be equipped with a mechanical chain coal-fired hot blast stove, which has strong adaptability to coal types, and the overall thermal efficiency can reach more than 80%. The average coal consumption per ton of precipitation is not more than 176kg of standard coal.

3.This machine also have gas cleaning system. With cyclone, air fan, wet dust filter. Without pollution.

4. The drum body adopts screw + plate structure, double-layer plate and turnover plate are continuously turned up and down to make the material fully touch with the hot air, promote the heat exchange, ensure the drying efficiency.

According to your raw materials, we also provide three-layer rotary drum dryer, three-layer rotary drum dryer which can improve the internal structure of the original single drum dryer, increase the pre-drying of wet materials before entering the machine and prolong the drying time of wet materials in the machine, Coupled with sealing, heat preservation and reasonable supporting measures, the production capacity of the dryer is increased by 48-80% compared with the original single cylinder dryer, the evaporation intensity per unit volume can reach 120-180kg/m3, and the standard coal consumption is only 6-8kg/t. Moreover, it effectively reduces the occupied area, and the smaller volume is convenient for sea transportation.
