Granulating knives - Import export

Optimum crushing instead of cable salad The very best method for crushing of cables or electrical scrap has brought many a tool to its limits and yet this is a frequently underestimated source of money. In addition to expensive copper, the recycling process also recovers aluminium and noble metals. In order to reach these valuable raw materials, robust preliminary crushing units are used, followed by a second crushing cycle. The demands on the crushing knives cannot be ignored and they must therefore be very tough. We are at the side of our partners to give advice on the selection of ideal materials and the best heat treatment.

Recycling made easy Our machine knives, of uncompromising quality, have been used for decades in recycling for tyre crushing. Even when separating rubber and spring steel, they have been proven in practice day by day. Whether shredder knives, spacers, scrapers or sealing gaskets, shredder teeth for multipleshaft shredders, rotary and stator knives for granulators or machine knives for guillotines Our complete range of products also covers the most demanding challenges in recycling.

Clothing instead of landfill PET must beone of the most interesting recycling materials of recent years as, during this time, not only new bottles, but also clothing and much more have been produced from recycled bottles. In Germany alone, each year the volume of PET bottles discarded when empty has exceeded 400,000 [tonnes], 96% of which is taken to professional recycling. An additional 60,000 tonnes arises annually as packaging material. However, PET is an extremely abrasive material, which exacts enormous demands on the tools used in recycling. Our knives have been proven by their high resistance to wear, and we also supply, in addition to our proven quality standards, extremely hardwearing special qualities.

Different tungsten carbide qualities with a hardness above those of the standard and PM special qualities. Through clean grinding materials, we achieve a long working life through high resistance to wear.

Extremely durable materials place extreme demands on the knives with which they are processed. Our knives are customized for a wide variety of material mixtures and therefore perform excellently in cold and hot cutting processes.
