Single-shaft shredder

Powerful shredders for precise size reduction

Single-shaft shredders have a rotor fitted with industrial cutting blades. These cut the material that the hydraulic pusher presses against the rotating rotor. The grain size, i.e. the size of the shredded material, is defined by a screen fitted below the rotor. Depending on the application, the holes are larger or smaller.

How does a single-shaft shredder work?

A single-shaft shredder uses a single rotating shaft with robust blades to precisely shred materials. The rotor turns against static counter blades, cutting the material into small pieces.

A hydraulic pusher ensures that the material is constantly fed. It pushes the material into the knives so that the shredding process remains constant.

An integrated sieve controls the particle size so that only material of the desired size passes through. This technology is very good for shredding wood, plastic, waste, paper and metals.

When is a single-shaft shredder used?

Single-shaft shredders are used wherever precise and homogeneous shredding is required. They are particularly suitable for processing plastic, wood waste, paper, metal and a wide variety of waste materials.

The versatile material compatibility and high flexibility make single-shaft shredders the ideal choice for businesses that require uniform particle sizes and high throughput rates. These machines offer a reliable and efficient solution for material processing. Single-shaft shredders enable precise shredding and are adaptable to different materials, making them particularly valuable in industrial applications.

Typical areas of application

Single-shaft shredders are used in various industries to efficiently shred materials. Typical areas of application are:

  • Plastics industry: Shredding of production waste, start-up lumps, pipes, PET bottles and other plastic parts.
  • Wood processing: Processing of wood waste, pallets, crates and furniture.
  • Waste management: Shredding of mixed waste for the production of refuse-derived fuel (RDF).
  • Paper and cardboard industry: shredding of paper waste, cardboard and confidential documents.
  • Metal processing: processing of metal waste and chips.

Advantages of single-shaft technology

Single-shaft shredders enable precise control of the particle size, which is particularly important for subsequent process steps. They are energy-efficient and robust: thanks to their durable design and low maintenance requirements, operating costs and downtimes are reduced.

Industrial shredders with single-shaft technology are highly adaptable to different materials. They can easily shred plastics, wood, paper, cardboard and metals. This makes them a flexible solution for many industries. Easy maintenance and quick access to wear parts ensure high machine availability and minimize downtime.

In addition, the efficient hydraulics and robust design contribute to the longevity of the single-shaft shredders. This further reduces the total cost of ownership. The combination of precision, versatility and cost-effectiveness makes single-shaft shredders an attractive investment for companies looking to optimize their shredding processes.
