Introduction：The bottom reinforcement device is designed with diamond shaped stirring teeth, and its streamlined performance reduces wind resistance. It is placed inside a conical hopper with a moving knife and a fixed knife, and the crushing effect is significant. The falling agglomerated material is quickly crushed into powder particles suitable for airflow drying. Another main function of stirring is to disperse the material, increasing the contact area with the high-speed hot air coming in from below the hopper. As a result, a strong heat and mass transfer fluidized bed is formed in the hopper area, an···
