Having problems with lifetime, throughput or cracking?
Ask for DURALIFE V+ KNIVES – the next generation of granulator knives
An industrial knife is the heart and soul of the recycling process. It crushes and mills different types of waste – reusable raw materials (PET, plastics, copper, aluminium, rubber etc.) into granulate. Waste is never completely homogeneous. Normally it contains a variety of foreign bodies, which is why knives are usually under constant pressure. Consequently, chipping and breaking of the blades occurs quite often and is nothing uncommon.
