Our rotary shears (PTRS)

Versatile, robust and ready for every challenge

Our two- and four-shaft PTRS rotary shears are equipped with powerful torque and designed to handle even the most challenging materials.

The rotary shear is the starting point for efficient recycling: it pre-cuts a wide range of materials, particularly in electronic waste recycling. The robust construction is designed for continuous operation.

Benefits at a glance

Convincing arguments

Torque and versatility

Powerful torque for wood, plastic, metal and other challenging materials, for a wide range of applications.

Robust construction

Designed for continuous operation. Minimal downtime ensures maximum productivity and profitability.

Perfect cutting results

Reliable, consistent cutting quality combined with long blade life.

Screen quick-change system

The quick-change screen allows precise control of particle size.

Cutter shaft quick-change system

Easily adjustable and replaceable blades for optimal efficiency and high availability.

Economical in operation

Regenerable cutting tools for cost-effective operations.

Precision down to the last detail

Engineered in every component

Feed hopper

Large central feed hopper, optionally with slide gate or customer-specific hopper solutions.

Shear shafts

The special arrangement of the shear tools delivers high cutting performance. Worn shear shaft sets are replaced, reconditioned and made ready for the next exchange.

Machine housing

The robust, one-piece steel welded construction easily withstands even the highest loads.

Drive

Variable frequency drive for precise speed control. A helical gear unit and electric motor drive each shaft individually; automatic reversal clears the system in case of overload.

Rotary shears in the recycling line

The ideal machine match for top results

E-waste: PTRS + PTV

The PTRS pre-cuts the input material. The PTV Balling Mill then prepares it for further separation.

Cables: PTRS + PTV

Pre-cut by the PTRS, the PTV specifically liberates valuable raw materials such as copper, aluminum and plastics.

Innovative battery recycling for tomorrow

In our battery recycling lines, two PTRS rotary shears work in sequence: the first performs coarse cutting of the batteries, the second enhances material separation.

  • Lift for transport boxes and feed via dosing hopper
  • 3-stage water spraying to prevent spark formation
  • Big bag filling and water separation, with the water filtered and reused
