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.

Knife manufacturing technology at SIJ Ravne Systems has evolved tremendously over the years to meet the increasing demand for cost-effective top-quality knives for specific industrial applications (metal industry, recycling, wood and wood processing industry and also paper and tire industry).
