[0002] During the lithium battery production process, metallic magnetic foreign matter may be generated. These foreign matter may come from equipment parts and tools that are not in direct contact with the material. Due to the collision between the material particles themselves or the impact with equipment parts, the crystal shape is destroyed, affecting the performance of the processed material.

[0003] During the use of the existing belt dryer, some materials are highly sticky and easily adhere to the conveyor belt, resulting in material waste. At the same time, when the existing belt dryer is working, the powder material falls freely by gravity, which will generate more dust and pollute the inside of the equipment. In addition, during the drying process of the existing belt dryer, the upper and lower layers of materials are prone to uneven drying. When the belt dryer is used for lithium battery production, since no flattening mechanism is set in the dryer, the material will have uneven thickness when falling to the lower belt, affecting the drying effect. There is a situation where particles collide with each other, destroying the crystal shape. Therefore, a material flattening device for a belt dryer is proposed. Utility Model Content
