As the field of use and demand for aluminum gradually expands, there is a growing interest in the aluminum recycling industry for processing waste aluminum into high purity aluminum granules.

In particular, various studies have been conducted on aluminum recycling having high purity and recovery rate because of high aluminum consumption and the high price of aluminum granules of high purity.

Accordingly, the present applicant has a technology for pulverizing waste aluminum scrap into aluminum chips in Korean Patent Registration No. 10-1207516 (name of the invention: aluminum scrap crushing device), and Korean Patent Registration No. 10-1310613 (Name of the invention: 6). In the single-sized aluminum granules high-speed pulverizer, the patent for the high-speed grinding of aluminum chips into fine-grained aluminum granules has been patented, but the research on the sorting device to increase the purity and recovery rate is insufficient.
