The invention discloses a crushing and grinding apparatus for processing cocoa beans. The apparatus comprises a shell, the shell is prepared from an aluminum alloy material, the upper left side of the shell is fixedly connected to a horizontal mounting seat, the horizontal mounting seat is welded to the shell, an electromagnet is fixedly connected to the left side of the upper part of the horizontal mounting seat, an upper translation rod is horizontally and slidingly connected to the upper part of the shell, the upper translation rod is prepared from iron, the left end of the upper translation rod fits to the electromagnet, the right end of the upper translation rod passes through the right side of the shell and is fixedly connected to a connection base plate, the upper and lower parts of the connection base plate are symmetrically and fixedly connected to first springs, left ends of the first springs are fixedly connected to the right side wall of the shell and the middle of the lower part of the upper translation rod is fixedly connected to a vertical base. Compared with the existing grinding apparatus, the crushing and grinding apparatus has a simple structure and is easy to use. In cocoa bean processing, through screening and grinding in two sides, processing efficiency is greatly improved and the ground cocoa powder particles are fine and smooth.
