When the rough grinding box 24 is replaced and maintained, the torsion bar 47 is rotated to control the rotation of one of the spur gears 45, and the two clamping jaws 46 on the same side are driven to open or close through the meshing of the spur gears 45, so that the limiting relation of the clamping jaws 102 on the rough grinding box 24 is controlled, and the rough grinding box can be taken out.

When carrying out preliminary crushing, through broken motor 14 work, with belt 15's transmission, two around driving it rotates mutually to changeing roller 18 to carry out preliminary crushing, the raw materials after the crushing pass through protruding board 19, the landing arrives both sides around the protruding board 19, through passageway 20 carries out the transportation work on next step.

The foregoing is merely exemplary and illustrative of the present invention and various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the scope of the invention as defined in the accompanying claims.
