Rotary Drum Mixer for BUSS Compounding Line in China

Overview

Lindor, engineering firm and machine manufacturer based in the Netherlands, has designed and delivered a state-of-the-art heated rotary drum soaker for polymer compounds to Switzerland-based BUSS AG.

The customized machine was designed to enhance product characteristics of special compounds to ultimately be made into a top-quality final product. These compounds are produced in BUSS AG’s compounding lines across multiple countries, including China, Spain, Saudi Arabia, and India.

This client success story focuses on the rotary drum soaker installed in BUSS AG’s newest compounding line in China.

The Polymer Processing Challenge

BUSS AG needed polymer compounding equipment that would deliver the highest quality of special compounds.

The application demands a design that minimizes contamination risks to achieve extremely high purity standards. It also demands an internal environment that maintains a stable temperature throughout the soaking cycle.

Additionally, the equipment needed to be accessible for easy and convenient cleaning, quality control and inspection.

Key features of the mixer-soaker include:

Precise Temperature Control: The drum and injection lance maintain set, stable product temperatures during the soaking process. Since the soaking solution is solid at cold temperatures, the lance heats and liquefies it. This allows the solution to be effectively sprayed onto the granulate. These features create uniform product heating, essential for high-quality special compounds.

Advanced Contamination Prevention: To meet extreme purity specifications of less than 1 part per million (ppm) contamination, Lindor designed a system which ensures that even the slightest wear does not lead to contamination.

Gentle Touch Technology: To protect the integrity of the particles throughout the soaking process, the mixer-soaker utilizes Lindor’s proprietary gentle mixing technology. The rotary movement of the particles through the drum is also what enables an even dispersion of the soaking liquid.

Quick and Easy Maintenance: Along with the hygienic internal design of the drum, the mixer-soaker includes retractable inlets and outlets on linear guides. The retractable system significantly speeds up cleaning and inspection processes. This feature allows BUSS AG to maintain high operational efficiency, even when frequent inspections are necessary.

Conclusion

Lindor’s state-of-the-art rotary drum mixer-soaker has proven to be an essential asset for BUSS AG’s compounding line in China.
Through customized solutions that meet stringent purity and operational demands, Lindor continues to drive innovation and production process development across multiple global locations for BUSS AG.
