Description

Can Crusher {CAN CRUSHER}

The present invention relates to a can grinder, and more particularly, to a can grinder to improve the recovery of useful metals (steel, aluminum) having high purity by cutting and grinding the collected cans to a certain size.

Commonly used cans are roughly divided into steel cans for accommodating various fruits, meats, fish, and the like, and aluminum cans for accommodating beverages and alcohol.

There are two ways to recycle such cans. For example, the collected cans are compacted in a compactor without being separated by material, and the volume is reduced and melted and recycled in an electric furnace. This is a method of visually sorting a number of workers, classifying them to some extent, and compressing and melting them to recycle them.

In the former case, the recovery rate of recovering only useful metals having high contents, such as high content of steel or high content of aluminum, is remarkably lowered. In the latter case, steel cans and aluminum cans are selected. In order to do this, a large number of working people are required and the work speed is slowed down, resulting in a decrease in work efficiency.

In order to improve this, a device for automatically sorting steel cans and aluminum cans is disclosed as Korean Patent Application No. 92-13228, 'Separation Method and Device for Recycling Cans'. The discharged cans are moved by a conveying conveyor for a predetermined period, and the moved cans are automatically selected by dropping magnetic cans and non-magnetic aluminum cans from different positions by the magnet of a roll installed at the end of the conveying conveyor.

Therefore, even if the steel cans and aluminum cans are not sorted individually, after being automatically sorted in the process of transport, the cans classified by each material are compressed and melted after delivery to obtain a high content of useful metals.

However, in recent years, in addition to the cans made of a single material, the composite material, that is, the body of the can is formed of steel having a predetermined strength, and the lid is made of steel-aluminum cans formed of aluminum. The problem was that steel and aluminum could not be completely screened, so that high purity useful metals could not be obtained.

In addition, the sorted cans are compressed with a compactor to reduce their volume before being transferred to the melting facility, where the compacted cans are simply pressed without being broken or crushed, so that impurities contained in them, such as dust and sewage, are Other materials, such as earth, paper, wire, vinyl, and cigarette butts, are also melted together in a compressed state, causing them to act as impurities, thereby lowering the content of useful metals.

The present invention has been made in view of the above-described problems of the prior art as described above. It is an object of the present invention to provide a can grinder capable of improving the recovery rate of very useful metals.
