Oliver Beiser, Business Segment Manager Chemical Applications, Coperion GmbH, Stuttgart/Germany

Producers of powder coating, adhesives, sealing compounds, toner, urea, laundry detergent etc. – numerous companies of the chemical industry rely on the first-class technology equipment of Coperion and Coperion K-Tron. We are longtime partners to the chemical industry and have comprehensive process engineering know-how.

We have realized plants and systems for a very wide range of chemical applications. And when our customers ask us to design the processing technology for a new product and the appropriate compounding system, this is the biggest incentive there is for us: to provide them with a customized solution tailored to their exact needs.

From Batch to Continuous – latest Success Stories

Our customer approached us with a request to help optimize his production process. Due to increasing demand, the existing batch process was not able to deliver sufficient product. Together we were able to successfully develop a continuous process on the ZSK co-rotating twin screw extruder. The results have proven that the mixing performance of the ZSK is superior to the traditional batch process. Capacities of up to 300 kg/h are possible. The material is directly transferred to the filling equipment.

Together with our customer we developed a complex continuous compounding line, including feeders for difficult to handle raw materials. The line processes sealants. Coperion delivered a complete production line, including raw material handling and discharge equipment. The process was developed and optimized based on Coperion’s process know-how and various trials in our test center in Stuttgart.

Your advantages when compounding with the co-rotating twin screw extruder ZSK:

  • Short residence time – low thermal stress for your
    product
  • Safe degassing for low residual contents
  • Good feed intake efficiency for low bulk density
    powders
  • Excellent mixing performance for highest dispersion
    requirements
  • Reproducibility with constant quality
  • High level of automation possible
