Disclosed is a meat grinder. According to the technical solution of this disclosure, food is placed into a processing cavity through a material inlet, and after the food is fallen to a side of a propeller away from a cutter head, the propeller is configure to propel the food to a cutter. The food is pressed against the cutter head and the food on the cutter head is cut by the cutter, and the food in discharge holes is squeeze outed by the propeller. Because the propeller is rotatably connected to the cutter head through the wear part, it may prevent an end of the propeller facing the cutter head from rubbing directly against the cutter head and causing black powder, so as to avoid the risk of contamination of the meat and affect the user's experience.
