The influence of 5 factors such as particle size,moisture content,preload,ultrasonic power and compression time to the drop resistance of wheat straw pellet in dual ultrasonic vibration assisted pelletizing were investigated to improve pellet durability. With the increase of particle size,the drop resistance of wheat straw pellet decrease. As preload,ultrasonic power and compression time increase,the drop resistance of wheat straw pellet increase. Moreover,with the increase of moisture content,the drop resistance of wheat straw pellet increase and then decrease.
