TWIST KEADING DISC "TKD"

Product catalog summary

Introduction
The document is a leaflet from The Japan Steel Works, Ltd., focusing on their Plastics Machinery Business Division. It introduces the Twist Kneading Disc (TKD), a new development aimed at improving energy efficiency and polymer temperature management in plastics compounding.

Specifications and Features
The TKD is designed to reduce energy consumption and polymer temperature by approximately 10% compared to conventional kneading blocks. Key features include:

Energy-efficient mixing at lower temperatures.
Disc elements divided and staggered at relative angles.
Availability of both forward and reverse flight combinations.
Disc tips that provide compression and shearing effects.
Improved filler dispersion and gel elimination.
Discontinuous disc tips for better dispersive mixing and higher processing rates.

Technical Outline
In twin screw extruders used for plastics compounding, kneading discs or rotor elements are typically employed. The TKD combines the advantages of both, offering more energy-saving mixing. JSW provides test equipment at their Plastics Machinery Developing Center in Hiroshima for trials.

Performance Data
Figures in the document illustrate the specific energy input and polymer temperature during ABC compounding using TEX65 at 1,000 kg/h. The data compares traditional kneading discs with the TKD and TKD combined with NIC, showing improved performance with the new technology.

Conclusion
The Twist Kneading Disc (TKD) represents an advancement in plastics compounding technology, offering significant improvements in energy efficiency and processing capabilities. JSW invites interested parties to contact them for trials and further information.

THE JAPAN STEEL. WORKS, LTD. LEAFLET TWIST KNEADING DISC "TKD" With advantages of both kneading discs and rotor elements Outline In plastics compounding by twin screw extruders, kneading discs or rotor elements are generally used for mixing section of the screws depending on the material and the application. Now, JSW has developed "Twist Kneading Disc (TKD)" so as to combine the strong points of both kneading blocks and rotor elements, which enables more energy-saving mixing than conventional kneading discs. We have the test equipment in our Plastics Machinery Developing Center in Hiroshima, Japan, which is available for your trial. If you are not satisfied with the conventional compounding system, please contact us any time! Features ■ Mixing with less energy consumption at lower temperature can be achieved with TKD. ■ A disc element is divided into several discs and staggered at a relative angle. ■ Both forward and reverse flight combinations are available. ■ Disc tips provide adequate compression and shearing effect to the polymer. ■ Mixing effect of a kneading block can be obtained with TKD as polymer passes through the gaps between staggered disc tips. ■ Disc tips provide good milling effect to improve filler dispersion or to eliminate gels in the products. ■ Discontinuous disc tips will be advantageous to better dispersive mixing and higher processing rate.
