Recycling knives and industrial machine knives for most challenging applications

Recycling knives and industrial machine knives

Recycling knives are industrial blades used in the recycling industry. As a vital component of shredding, granulating and reducing metal, industrial and municipal waste, they are available in a large spectrum of different steels and hardness. Custom manufacturing allows for industrial knives and blades to be used, in the reduction of waste, such as:

  • Pallets
  • Wood
  • Rubber
  • Medical waste
  • Plastics
  • Tyres
  • Aluminium
  • Copper
  • Biomass
  • Batteries textiles
  • Oil filters
  • PET
  • Ferrous and non-ferrous steels
  • Cast iron


The invention of blades as tools dates back to prehistoric times when they were made of flint. Over time materials have vastly improved, and today they are an essential part of global industrial production. The proper use of industrial blades affects the quality of end products, so it’s paramount to get the right one for the job. The appropriate knife will allow for the efficient completion of the desired task, no matter what that task may be.

Custom industrial knives for recycling and what are their key attributes?

Recycling knives are a crucial part of any waste management. Many businesses are implementing recycling in their manufacturing plants as it brings advantages which can’t be disregarded. The correct disposal of waste reduces cost, lessens the need for landfills, creates new jobs, and is more efficient. And we must not forget that it saves resources and energy. If the industrial plant produces waste in larger quantities, waste management can be a challenging process, so it’s essential to choose suitable  industrial knives and blades for:


  • Shredding

Tools for shredding are used for volume reduction of industrial waste such as plastic, paper, aluminium, textiles and much more. The product range includes shredder blocks, hammers etc.


  • Granulating

Blades for granulation are used for recycling reusable raw materials into granulate. The materials such as copper, PET, rubber and plastic are granulated with a rotor, stator and pelletizer, or fly and dead and bed blades.


  • Scrap metal recycling

Recycling knives for scrap metal are used for recycling a wide array of non-ferrous and ferrous steels and cast iron. Among commonly used machines are scrap shears, baler and alligator shears, wear plates, rotary shears, etc.

Ravne blades have multiple key attributes that change efficiency and productivity. State-of-the-art tools have a longer life span and lower energy consumption.

The higher performance and better values of new products are the results of metallurgical and engineering know-how. Innovative technology allows for better control of the process and lower service/operations costs. Industrial machine knives are easy to handle, designed to cut various materials and used correctly provide the best quality cut. Less friction ensures less damage to the material and a cleaner cut.


How to choose the appropriate industrial knives and blades for the job?

Recycling knives have to provide reliable cutting solutions that are cost-effective, consistent and have a quick turnaround time. All industrial cutting applications have specific requirements that must be met. The technology has evolved extensively to meet the increasing demand for cost-effective yet high-quality tools. Custom industrial knives are often the best choice as blades are designed to exact tolerances, particular economical solutions and broad capability.

Most purchases are typically made based on price, but when buying cutting tools is required to consider much more than just the cost. Making a decision solely on price can affect cutting performance, slit form and durability. When purchasing a recycling knife, one should pay attention to the materials and the design. To guarantee optimal quality, these must be made of the most suitable steel for application.

That will provide the best correlation between toughness and hardness. They should also undergo advanced heath heat treatment procedures, to ensure the highest percentage of hardness to safety against cracking. The design of industrial machine knives should be custom-made to waste materials and their particular requirements. Customisation increases the machine’s uptime, lowers energy consumption, improves durability and enhances machine output.

3, factors that are affecting the durability of the recycling knives the most

These have a life span that is measured in terms of the amount of work completed before they lose their effectiveness. Their durability directly affects the operating cost, so careful consideration when purchasing is required. The factors that most often influence the life of industrial machine knives are:


  1. Material and structure

Finest materials can help the blades endure challenging working conditions by preventing blunt edges. When choosing the tools, it is critical to know more about material analysis, surface quality, structure or strength, material combination and fibre orientation.

  1. Application conditions

The correct cutting and speed are based on dimensions, so the material has to be determined, before first-time use.


  1. Regular cleaning and maintenance of the machine

Regular cleaning and maintenance of the machine will ensure safe operation and prolong the life span. Removal of the collection of chips near the frame and checking the machine’s condition will tremendously improve industrial procedures.
