Metal powder coarse grinding equipment

The utility model discloses metal powder coarse grinding equipment which comprises a base, a first motor is installed at the top of the base through bolts, a bearing plate is installed on a power output shaft at the top of the first motor through an installation frame, an annular sliding groove is formed in the surface of the periphery of the bottom of the bearing plate, and a sliding rod is connected into the annular sliding groove in a sliding mode. According to the metal powder rough grinding equipment, the first motor can drive the storage barrel to rotate anticlockwise through the bearing plate, the second motor can drive the grinding roller to rotate clockwise, and therefore when the grinding roller is located in the storage barrel, metal scraps in the storage barrel can be fully overturned due to opposite acting force, and the metal scraps are ground into the storage barrel. In addition, the sliding rod is located between the bearing plate and the bottom plate, so that downward force borne by the stora
