It solves the problem that existing mixing devices, which only use a single rotating shaft and blades for mixing, have insufficient mixing at the bottom and edges of the tank. This results in materials easily sticking to the tank wall during discharge, eventually forming a hard crust, which reduces the effective volume and affects the mixing quality.
