Description

Discrimination system, discrimination method, and control program The present disclosure relates to a separation system, a separation method, and a control program for separating Automobile Shredder Residue (ASR) recovered from shredded materials generated by shredding a vehicle. In recent years, the recycling of ASR has been progressing. Consequently, there is a need not only to separate the shredded material generated by crushing vehicles into ASR containing useful metals and organic components such as hardened plastics, but also to recover the ASR by separating it more finely. For example, Patent Document 1 discloses a method for treating a mixture of fragmented materials consisting of a small amount of used polymer material recyclable in the field of plastic technology and contaminants, which is generated by crushing the durable consumer goods at the end of the durability consumer goods' lifespan. Furthermore, there is a need to not only separate the shredded material generated by shredding vehicles into ASR containing useful metals and organic components such as hardened plastics, but also to recover the ASR by separating it more finely. The present disclosure is made in consideration of the above background and aims to provide a separation system, a separation method, and a control program capable of finely separating and recovering ASR recovered from shredded material generated by shredding a vehicle. The separation system according to the present disclosure is a separation system for separating Automobile Shredder Residue (ASR) recovered from shredded material generated by shredding a vehicle, and comprises a first sieve for separating the ASR into a first ASR having a particle size smaller than a first particle size and a second ASR having a particle size greater than or equal to the first particle size; a first dry specific gravity separation device for recovering glass by performing dry specific gravity separation on the first ASR; a second dry specific gravity separation device for recovering cured plastic by performing dry specific gravity separation on the second ASR; and a separation device for separating at least metal and organic components from the first ASR from which the glass has been recovered and the second ASR from which the cured plastic has been recovered. By doing so, the separation system can finely separate and recover the ASR recovered from shredded material generated by shredding a vehicle. In addition, this separation system can prevent the separation device from malfunctioning due to glass by removing glass from the ASR recovered from the crushed material using a sieve before performing separation treatment. Furthermore, this separation system can recover hardened plastic by performing dry specific gravity separation on the ASR from which glass has been recovered. In other words, this separation system can separate and recover the ASR more finely. The system may further provide a crushing device for crushing the second ASR. The crushing device may be configured to crush the second ASR to a particle size corresponding to the first ASR. By doing so, the separation system can perform separation treatment for each of the two types of ASR using a common separation device. A plurality of slits may be formed in the first sieve. The width of the slits in the first sieve may be 10 mm or less. By doing so, this separation system can recover glass with higher precision. The above-mentioned first ASR may further be provided with a second sieve for separating the first ASR into two types of particle sizes, and the first dry specific gravity separation device may be configured to perform dry specific gravity separation on the first ASR of the smaller particle size among the two types of first ASRs separated by the second sieve. By doing so, the separation system can separate and recover the ASR more finely. The above-mentioned second ASR may further be provided with a third sieve for separating the second ASR into two types of particle sizes, and the second dry specific gravity separation device may be configured to perform dry specific gravity separation on the second ASR of the smaller particle size among the two types of particle sizes separated by the third sieve. By doing so, the separation system can separate and recover the ASR more finely. In addition, the separation method according to the present disclosure is a separation method by a separation system for separating Automobile Shredder Residue (ASR) recovered from shredded materials generated by shredding a vehicle, wherein the ASR is separated into a first ASR having a particle size smaller than a first particle size and a second ASR having a particle size greater than or equal to the first particle size by using a first sieve, glass is recovered by performing dry specific gravity separation on the first ASR, and hardened plastic is recovered by performing dry specific gravity separation on the second ASR, and at least metal a
