It is the current situation that some kinds of shretting machine manufacturers have already thrown spoons.

The present inventor has also been involved in the crushing and recycling of the mall since around 1975, and tried variously with a conventional shreter or a modified shreter, but it was absolutely crushed metal and crushed non-metal. It did not reach the point where it was separated and separated into two and reused as resources.

On the other hand, the molding manufacturer side also separates and sharply separates the molding into crushed metal and crushed non-metal,
It is absolutely impossible to reuse them as resources, and we have no choice but to discard these malls as they are, incinerate them,
Or, it is the current situation that it is buried and disposed, for example, reduction of the disposal site, generation of secondary pollution, specifically, generation of air polluted air due to generation of chlorine gas, generation of soot pollution, or This is a serious social problem in that effective use of resources is not achieved.

[0008]

Therefore, according to the present invention, the mall, which has been conventionally disposed of, is separated into crushed metal and crushed non-metal, and used for recycling, so that the so-called resource is effectively used. The following configuration was adopted for the purpose of solving various problems caused by disposal, etc.

That is, the shredder for crushing automobile moldings according to the present invention comprises a conveying means such as a conveyor for feeding the automobile moldings to be crushed, and the automobile moldings supplied from the conveying means in the next step. A supply casing having a pair of supply rolls to be fed, and a receiving port that is connected to the supply casing and receives the automobile molding,

After that, the separated crushed metal is magnetically adhered to a magnetizing roller, and in this example, on the crushed metal conveying conveyor arranged in the same direction as the vibrating plate, for example, a stopper mounted on the magnetizing roller. Via the crushed metal transport conveyor, and then transferred to a predetermined place.

On the other hand, the crushed nonmetal collected in the concave portion of the diaphragm is stored in the shooter box and then transferred to a predetermined place via the crushed nonmetal transfer conveyor.

By repeating the operation or procedure detailed above, the molding is separated into crushed metal and crushed non-metal,
After being classified and collected, they are reused as resources. Specifically, crushed metal is used as a steelmaking casting material,
Further, fine metal particles are further separated from the crushed non-metal and reused as rubber raw materials.

The shreter casing is constructed so that it can be opened. For example, it is released from the need to replace a worn hammer or the same wall component (liner). The means (tightening bolt) is removed (opened), the cylinder is actuated, and the upper casing is swung in the arrow direction as shown by the chain line in FIG.

As a result, the shredder casing is opened, so that the above-described replacement work, other repair work, cleaning work and the like are performed.

After completion of each of the above operations, the cylinder is operated, the upper casing is joined to the lower casing, and then the fixing means is attached.

When the hammer shaft of the shretting drum is to be removed, the hammer shaft is removed via the hammer shaft inserting / removing device, and then the hammer is removed from the shretting drum.

Then, after mounting a new hammer in the shretting drum, the hammer shaft is inserted into the shretting drum through the hammer shaft inserting / removing device.

As a result, the replacement of the hammer and the mounting of the new hammer are completed, so that each of the other hammers can be replaced through the same operation and procedure if necessary.

The operation and the operation of the cylinder and the like described above are comprehensively and automatically controlled through the computer and images in the control room.
