Specialization:
a)Mainly and specially for powder biomass raw material, such as sawdust or grinded wood powder.
b) Three-pass dryer, longer mixing duration of hot air and material.
It is with high drying efficiency, heat utilization ratio and less space needed.
The floor space is 30% less than single drum dryer with same capacity.
c) Support of roller ring and retainer wheel are integral cast steel structure,
with high strength, stable operation, anti-abrasion and long service time.
d) Convenient feeding, feeding from middle of dryer by screw conveyor or
from the top according to the different materials.

Application for the drum dryer in Biomass pellet line:
Step1: Raw Material Receiving and Wood Chipping Process
The user provides log diameter 100-300mm usually.
we choose the different slicer according to the different capacity.
the chipper thickness is 15-38 mm after chipping. Slicer is divided into disc and drum slicer two kinds.
Step 2:Grinding process
After drying the raw material into the mill, it is generally the size of 5cm, the size after the pulverization is about 6mm. Grinder works: mill rotor high speed operated by the rotor with a hammer rotation speed of 3000 revolutions per minute, high-speed hammer blow raw materials.
Step3:Drying process
Dryer is applicable for drying of straw, long fiber, particles, wood chips and sawdust. It
features with low electric quantity and low energy consumption, and it can regulate the drying speed according to the moisture requirement.
Dryer can be customized according to the material moisture content provided by clients.
YLGH series Dryer developed by YONGLI is a kind of 3-layer drum dryer.
It can dry material by evaporation and heat exchange with the Boiler. Inlet air temperature of dryer is regulated by thermo-sensor. The inlet temperature is around 500-600℃.
The water content before drying is usually 15-60% and the moisture of material after
drying is around 10%-12%.
Step4: Pelleting process
The model of Pellet Mill is determined by the required capacity by client. The diameter is always 6mm, 8mm, 10mm or can be customized according to clients’ requirement.
Conditioner is optional. The conditioner can make the material easier to pelletize, improve the capacity, save energy and prolong the service life of ring die and rollers. By conditioning, the material can be softened. During the process of squeezing of material between roller and inner side of ring die,large amount of mechanical energy will be turned into heat energy.
Step5:Cooling and Screening and Bagging process
Cooler is mainly used for cooling of particle material. The temperature of pellet after pelletizing is always 70-90℃, this process is to make the temperature a little higher than
ambient temperature (generally not higher than 3-5℃).
The hardness of pellet after cooling is strengthened, and is convenient for storage and transportation.
Rotary Sifter: greater than and less than the screen mesh material to separate materials. Screen surface material is left to the finished product, the material needs to be re sieve granulation.
Packaged scales: small package available packaged (usually 15-50kg / pack)
and tons of bags packed (500-1200kg / pack) according to customer needs.
