A variety of raw materials are added to the stirring tank, and the materials are sheared and mixed by the rotation of the stirring paddle. After stirring and mixing, the mixture is poured out. However, when a variety of different powders are poured into the existing powder mixing device, the powder coating finally poured into the stirring tank will be on the top of the whole powder. Therefore, during the stirring process, the mixing of the powder coating can only be completed by the rotation of the stirring paddle.
