Bed knives for granulators
Bed knives, also known as stationary knives, are a crucial component of granulators used in plastics recycling. They are mounted on the grinding chamber of a shredder and serve as the counter-knives to the rotor knives, also called fly knives, which cut against them. Together, they shred and finely grind production waste into smaller particles.
The distance between bed knives can be adjusted depending on the input material, which ensures a clean cut of the material. While the cutting angle of fly knives is mostly flat, bed knives often have a steeper angle. This difference in angle helps ensure a smooth and efficient cutting process.
Bed knives can be made from a variety of materials, including tool steel, tungsten carbide, and ceramic. Different materials and cutting geometries can be used to optimize the performance of the bed knives and rotor knives. For example, flattened cutting angles result in a more aggressive cut, while knives with a pre-bevel have a more stable cutting edge.
The target hardness of the material for fly knives and bed knives is variable to ensure optimal performance for different areas of application and input materials. Proper maintenance and replacement of bed knives are essential to ensure the longevity and optimal performance of granulators. With regular maintenance, bed knives can provide efficient and reliable operation in plastics recycling for many years.
