In the crusher of the above type, dust is crushed by using a link chain as a hammer. Therefore, the link chain to be used is less likely to be damaged and should be durable. .

Further, flexible dust such as vinyl sheets is discharged as it is without being crushed, and dust such as wood which is softer than glass is discharged without being crushed as much. However, this kind of dust is also desirably cut or crushed to some extent because it can be smoothly discharged without staying in the crusher.

[0006] Further, it is desirable to enhance the discharge efficiency of the blower that discharges the crushed dust from the crusher.

[0007] In view of the above, the object of the present invention is to provide:

The dust introduced from the dust inlet 21 is first subjected to a crushing action by the wrap-around blade 14, and the long string, cloth, etc. contained therein are mainly divided. Next, under the crushing action of the plate-like crushing blade 16 arranged below,
Dust such as vinyl sheets is cut or cut into a predetermined size. In addition, dust of soft materials such as wood is mainly crushed.

Thereafter, the dust dropped from the dropping port 73a of the partition plate 73 is subjected to a crushing action by the upper and lower link chains 17 in three stages. Due to the crushing action of these link chains 17, the dust is crushed into a predetermined size.
The dust crushed by the link chain 17 is further pulverized by a long plate-shaped crushing blade 18 disposed below the link chain, and is finely crushed. The plate-like crushing blade 18 separates and crushes dust such as vinyl sheets and wood.

The crushed dust that has been subjected to the crushing action as described above is dropped or sucked from the suction port 19a of the annular plate 19 into the exhaust fan 41. The crushed dust receives the exhausting action of the exhaust fan 41 and is blown out from an exhaust port 24 formed in the outer peripheral surface in a tangential direction of the outer peripheral surface. The crushed dust discharged to the outside by the air flow in this way is sent to the sorter 3 as described above and undergoes a sorting action (see FIG. 1).

The crusher according to the present invention is characterized in that a circular slotted ring hammer is connected to the end of the link chain, and the use of a link chain having this configuration reduces the occurrence of damage to the link chain. As a result, the effect of increasing the durability can be obtained.

Further, the crusher of the present invention is characterized in that plate-like crushing blades are arranged above and below a link chain.
By arranging the plate-shaped crushing blades, it becomes possible to cut or cut small size vinyl sheets and the like. In addition, dust and crushing of soft materials such as wood can be performed more efficiently and reliably than a link chain.

Further, the crusher of the present invention is characterized in that a notch or a slit is formed on the inner peripheral edge of the annular plate defining the suction port of the exhaust fan, and the annular plate having such a shape is used. Thereby, the crushed dust can be efficiently sucked, and the exhaust function can be enhanced.
