초록
Plastic products are widely used in daily life as well as in various industries. Althoughthe amount of plastic waste increases every year, there are few studies on waste plastic recyclingand automated facilities. Only 31% of waste plastic is recycled, which leads to seriousenvironmental problems. Also, because plastic raw materials are all imported, the unit price ishigh; therefore, the use of recycled plastic raw materials is essential for price competitiveness andenvironmental protection. In this study, we developed a pelletizer device capable of producing thematerial size (4~7mm) of recycled plastic desired by consumers. Also, we developed a vibratordevice capable of separating the produced pellet raw materials from externally introduced dust,chips, and defective raw materials. Then an automated facility was built using these devices. Thiswas evaluated, and production was shown to increase by more than 20% compared with existingdevices.
