The fly ash is taken out, a semicircular arc-shaped support trough 2 is fixedly installed at the lower part of the inner wall of the box body 1, and two pulleys 3 rotatably installed on the inner wall of the box body 1 are arranged horizontally above the support trough 2, one of which is connected to a power mechanism, and the power mechanism includes a first motor 10 fixedly installed horizontally on the outer wall of the box body 1, and the output shaft of the first motor 10 rotates and penetrates the box body 1, and the output shaft of the first motor 10 is fixedly connected to the shaft of one of the pulleys 3, and the two pulleys 3 are connected through a belt 4. A support frame fixedly installed on the inner wall of the box body 1 is provided on the side, and the support frame provides auxiliary support for the belt 4 to prevent the belt 4 from bending. A plurality of fixed plates 5 are fixedly installed on the outer wall of the belt 4 at equal intervals. A grinding trough 6 penetrating up and down is fixedly installed on the inner wall of the box body 1, and a grinding block 7 is vertically arranged in the grinding trough 6. The grinding block 7 is connected with a driving mechanism, and the driving mechanism includes a second motor 11 vertically fixedly installed on the upper wall of the box body 1. The output shaft of the second motor 11 rotates through the box body 1 and is fixedly connected to the upper surface of the grinding block 7. A screening plate 8 slidingly matched with the side wall of the box body 1 is obliquely arranged below the grinding trough 6. The lower end surface of the screening plate 8 is fixedly connected to the upper end surface of the support trough 2 through an elastic pad 9. The screening plate 8 is connected with a vibration control mechanism. The device performs grinding by arranging the grinding trough 6 and the grinding block 7, and arranging the first motor 10 to indirectly drive the fixed plate 5 to circulate, so that the fly ash that does not meet the standard after grinding is sent back to the grinding trough 6 for grinding again, and the fly ash is cyclically ground for multiple times, and the grinding is more efficient and delicate.

The fixed plate 5 moves synchronously with the transmission of the belt 4, the second motor 11 directly drives the grinding block 7 to rotate, and the third motor 12 drives the connecting shaft 14 to rotate through the transmission of the adapter plate. The rotation of the connecting shaft 14 drives the slotted plate 13 to move up and down, and indirectly drives the screening plate 8 to move up and down, and the fly ash enters the box body 1. After the grinding block 7 and the grinding trough body 6 cooperate to grind, the ground fly ash falls on the screening plate 8, the qualified fly ash falls to the bottom of the box body 1 through the screening plate 8, and the unqualified fly ash falls into the supporting trough body 2 with the vibration, and the fixed plate 5 moves to send the fly ash back to the grinding trough body 6 for grinding again. Repeat the grinding cycle for many times to grind the fly ash to the standard specification.
