In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the utility model. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0045] In the specific use of this embodiment, when it is necessary to crush the high-titanium slag, the crushing motor 84 is first started through the external PLC, and then a proper amount of high-titanium slag is added to the crushing box 1 through the feed hopper 3. At this time, the output shaft of the crushing motor 84 rotates to drive the crushing roller 81 on the same side connected to it coaxially, and the rotation of the crushing roller 81 drives the driving gear 83 on the same side fixed coaxially with it to rotate, and the rotation of the driving gear 83 drives another driving gear 83 meshing with it to rotate, and the rotation of the other driving gear 83 drives the other crushing roller 81 to rotate. The two crushing rollers 81 rotate in opposite directions, so that the rotation directions of the several crushing teeth 82 on the outer walls of the two crushing rollers 81 can also be opposite, so that the high-titanium slag added to the crushing box 1 can be pre-crushed;

[0046] When the pre-crushing is completed, the crushing motor 84 is turned off and the electric cylinder 79 is started through the external PLC. The movement of the piston rod of the electric cylinder 79 drives the frame 76 fixed with it through the gasket 710 to move. The movement of the frame 76 drives the roller 77 and the grinding roller 78 to move. When the distance between the grinding roller 78 and the inner bottom surface of the crushing box 1 is appropriate, the electric cylinder 79 is turned off through the external PLC. Then, the output shaft of the grinding motor 714 is started and controlled by the external PLC to rotate alternately forward and reverse. The rotation of the output shaft of the grinding motor 714 drives the rotating shaft 715 coaxially connected thereto to rotate. The rotation of the rotating shaft 715 drives the grinding gear 713 on the same side coaxially fixed thereto to rotate. The rotation of the grinding gear 713 drives another grinding gear 713 meshing with it to rotate. The other grinding gear The rotation of 713 drives the rotating rod 712 fixed coaxially therewith to rotate, and the rotation of the rotating rod 712 drives the screw 72 fixed coaxially therewith on the same side to rotate, and the rotation of the screw 72 drives the moving plate 73 threadedly connected therewith to move, and the moving plate 73 moves under the guidance of the two guide blocks 74, the guide rod 75 and the two guide grooves on the inner wall of the crushing box 1, and the movement of the moving plate 73 indirectly drives the rotating roller 77 and the grinding roller 78 to move, and the grinding roller 78 rotates while moving, because the output shaft of the grinding motor 714 rotates forward and reverse alternately, so that the rotating column 71 can rotate forward and reverse alternately, and then the grinding roller 78 can make a reciprocating motion in the horizontal direction, so that the high titanium slag can be ground, and when the grinding is completed, the grinding motor 714 is turned off by the external PLC;

[0047] Then, the electric push rod 43 is started through the external PLC, and the movement of the piston rod of the electric push rod 43 drives the lower connecting plate 44 fixed to it through the contact piece 45 to move. The movement of the lower connecting plate 44 drives the baffle 41 fixed to it to move. When the baffle 41 no longer blocks the discharge chute on the front surface of the crushing box 1, the electric push rod 43 is closed through the external PLC, and the high-titanium slag inside the crushing box 1 can be discharged.
