Kneaders are always used when high-viscous materials have to be kneaded intensively and absolutely free of contaminants. During the kneading process, the product neither touches shaft seals or bearings, nor thus remains absolutely free of even the smallest contaminations.
Working Principles
Kneading machine commonly offers 2 drive motors, which permits additional speed adjustment between the two kneading blades. This allows even sticky materials like hotmelts to be processed in a vertical kneading machine. In standard planetary mixers, these materials climb up at the kneading blades, and were not affected by the shear forces.
Common Applications
- Silicone compounds
- Master batches for the automotive industry
- Ceramic compounds
- Hard metal compounds
- Graphite compounds
- Catalyst compounds
- Biodegradable plastics
Advantages
Fully continuous production with no breaks Easy to automate Less space required for the same production quantity More intensive thorough mixing Less space required Longer, adjustable residence time in the mixer High solids contents achievable Flexible configuration of the machine (depending on product requirements) enabling product change without conversion of the machine
