Coperion delivered the entire solution from raw material handling receiving to the handling of finished goods, including three ZSK 70 Mc 18 twin screw extruders assembled locally at Coperion Nanjing, strand pelletizers from Coperion Pelletizing Technology, a silo washing system and the Distributed Control System (DCS). Up to now, the new Smart Compounding Lines are running re- liably at the highest throughput rates and Coperion will further support Nanjing Julong as a service partner. Coperion will pro- vide the site and spare parts service for the entire plant. High Level of Automation for Maximum Plant Efficiency Together with Julong, Coperion’s engineering teams in Shanghai and Nanjing have planned, developed and designed the entire factory from layout to commissioning. Based on the extensive know-how collected from more than 150 installed compound- ing lines, one of Coperion’s main focuses was on user-friendly plant design by improving the working conditions for the ope- rators at every step of production. The result comprises a high level of automation and digitalization of Julong’s plants. Central functions are performed by the DCS Control System which has an interface and signal exchange with Julong’s Manufacturing Execution System and supports and improves Julong’s automat- ed processes from order handling to manufacturing and thus in- creases the efficiency of the entire production. ZSK Twin Screw Extruders Form the Heart of the Compounding Lines The three Smart Compounding Lines are each equipped with a ZSK 70 Mc 18 twin screw extruder with a screw diameter of 70 mm and a specific torque of 18 Nm/cm³. ZSK extruders are ideal for processing products with a high torque requirement, such as PP and PA. The ZSK 70 Mc 18 twin screw extruders are lo- cally assembled at Coperion’s manufacturing site in Nanjing, China. Chinese customers benefit from local added value, trans- port, and tax savings as well as from shorter delivery times. Even the after-sales services are customized to local parts and needs. Coperion’s SP Treasure Strand Pelletizers Produce High Quality Pellets Julong’s three Smart Compounding Lines are equipped with Coperion’s SP 320 treasure strand pelletizers. This strand pelle- tizer series was developed through close cooperation between Coperion Pelletizing Technology, Offenbach, Germany and Coperion Nanjing. Coperion Pelletizing Technology is respons- ible for the design and manufactures the cutting chamber. The remaining pelletizer assembly is manufactured locally in Nanjing. The SP 320 treasure strand pelletizer is ideally suited for proces- sing of highly abrasive strengthened products. It has a working width of 320 mm and can process up to 88 strands at throughput rates of up to 2,500 kg/h. Key design features of the SP treasure pelletizer include high throughput rates, excel- lent accessibility and ease of cleaning. Strategy Results in Fast Return on Investment The successful operation of Julong’s three Smart Compounding Lines is proof of Coperion's many years of experience in the reali- zation of turnkey solutions. Coperion exclusively uses high-qua- lity, tried-and-tested components within Smart Compounding Lines – a strategy which results in high process safety and user- friendly system design with consistently good product characte- ristics and a long service life. Considering this first-class, reliable technology along with optimum interaction of all process steps and the high throughput rates of the three compounding lines, the return on investment will quickly be achieved. In addition, Ju- long will continue to benefit from available local spare parts, avoiding time-consuming and expensive import procedures. 35 Extrusion Asia Edition 1/2022
