Twin-shaft shredder

Heavy duty pre-shredders for extreme applications

WEIMA twin-shaft shredders are characterized by high throughput rates and maximum robustness. Thanks to their counter-rotating cutting shafts, they can easily grasp and efficiently shred even large and heavy materials.

The special cutting geometry and overload protection ensure smooth operation. This also applies to difficult materials such as metal, Wood
oder Plastic. These machines are ideal for recycling applications where reliable performance and durability are required.

How does a twin-shaft shredder work?

A twin-shaft shredder works with two shafts arranged in parallel and rotating in opposite directions, which are equipped with robust cutting tools. As soon as the material comes between the two shafts, the cutting disks grip it. The combination of pressure, pulling and cutting movement tears it apart and shreds it.

The special arrangement of the disks allows the material to be constantly picked up and processed. This ensures an even and efficient shredding process.

Twin-shaft shredders are designed in such a way that they can shred even bulky or heavily contaminated materials without disruption. Depending on requirements, different cutting geometries and rotation speeds can be adjusted to achieve the ideal final size of the material.

Customized cutting configurations

The cutting shafts can be equipped with eight to twelve cutting disks, depending on the desired throughput rate and grain size. The size of the shredded material is determined by the number and width of the cutting disks.

Where are twin-shaft shredders used?

Twin-shaft shredders are used in particular when it comes to pre-shredding bulky, large and mixed materials. Typical applications include the shredding of metals, plastics, wood and textiles. Industrial waste is also processed. The processing of bulky waste and construction waste is also included.

This technology is perfect for recycling plants. It can process large quantities of material efficiently. The machine is very robust and resilient. This makes it a reliable solution, even for contaminated materials.

The machine is very robust. Therefore, materials such as waste wood or plastics can also be shredded. Metallic foreign bodies do not need to be removed beforehand.

At a customer in Brescia, Italy, an M8.28 twin-shaft shredder with hydraulic drive shreds various types of waste. This includes bulky waste, household waste as well as municipal and industrial waste.

Advantages of twin-shaft technology

The use of a twin-shaft shredder offers the customer a number of advantages. Thanks to its robust and durable design, the machine is particularly resistant and significantly reduces maintenance costs.

The twin-shaft technology offers a high throughput rate. This means that large quantities of material can be shredded quickly. This is ideal for companies with a lot of material.

Another important advantage is the flexibility of the machine. Different types of material can be shredded. This is done without time-consuming pre-selection. There is no risk of blockages or machine downtime.

The low dust formation and energy efficiency of the twin-shaft shredder help to keep operating costs low. It is also environmentally friendly. The twin-shaft technology thus provides a reliable and cost-efficient solution for companies that require effective pre-shredding of their materials.
