The support pad 92 and the support rod 91 can support the crushing box 1 on a support surface such as the ground.

When slag is crushed by using the slag crushing device of the present embodiment, slag to be crushed is charged from the feed port 13 of the crushing tank 1, and at this time, the first and second drawing plates 511 and 512 of the first door mechanism 5 are in a closed state. The first and second crushed pieces 32 and 33 are moved toward the crushing plate 31 by the start motor, and slag located between the crushed pieces and the crushing plate 31 is crushed by the crushing. And simultaneously, the motor is started to enable the optical axis 41 of the screening vibration mechanism 4 to vibrate left and right, so that slag in the primary crushing mechanism 3 is layered and crushed in a grading manner. After the primary crushing is completed, the first drawing plate 511 and the second drawing plate 512 of the first door body mechanism 5 are opened, so that the slag after the primary crushing falls into the cone crushing mechanism 2 for further crushing. When there is a demand for producing slag powder, a grinding mechanism 6 is installed below the cone crushing mechanism 2, and slag particles crushed by the cone crushing mechanism 2 fall into the grinding mechanism 6 to be ground into slag powder.

The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
