Grinding equipment for producing wheat flour

The invention relates to the technical field of grinding equipment, in particular to grinding equipment for producing wheat flour, which comprises a containing box, an annular supporting seat mounted at the bottom end in the containing box, a grinding seat movably arranged on the annular supporting seat, and a box cover arranged above the containing box, a rotary driving device is arranged in the middle of the lower surface of the inner wall of the containing box, a grinding groove is formed in the middle of the upper surface of the grinding base, and the grinding groove and the backflow hole form an annular backflow channel. The backflow holes are formed in the periphery of the inner wall of the grinding groove, so that the ground small and light wheat flour raw materials can enter the backflow holes, meanwhile, the rotating speed of the grinding base is increased, and the wheat flour raw materials located at the bottom can be diffused to the periphery of the inner wall of the grinding groove to be ground; a
