UNIQUE FEATURES AND ADVANTAGES OF THE CASTOR DESIGN – Part 1/2

The shredding chamber can be opened and cleaned from two sides – from below by manually lowering the screen holder and from above by tilting back the feed hopper. This design is rare on the market.

The screen, which determines the size of the shredded material, is simply a curved perforated metal sheet. The reinforced screen holder is a separate component that remains in the machine when the screen is replaced. This distinctive design provides significant additional benefits for the operator.

The elevated position of the shredding chamber allows shredded material to be collected in a container or discharged using a belt conveyor, screw conveyor or pneumatic conveying system, without the need for an additional machine stand.

The large rotor diameter (400 mm) enables the cutting tools to effectively grip and process relatively large items. The large rotor diameter also provides a greater screen surface area, contributing to high shredding throughput.

The CASTOR is available with either a single drive (22 or 30 kW) or two drives (2 × 22 kW). Rotor lengths of 600 mm, with 12 or 24 rotor knives, and 1,000 mm, with 21 or 42 rotor knives, are also available.

UNIQUE FEATURES AND ADVANTAGES OF THE CASTOR DESIGN – Part 2/2

The CASTOR single-shaft shredder features a unique arrangement of two identical stator knives positioned within the shredding chamber so that each rotor knife makes two cuts per rotor revolution. The radially adjustable position of the stator knives and the optimised geometry of the rotor and stator knife arrangement improve shredding throughput and overall process efficiency. Furthermore, this design allows the CASTOR to operate with or without a screen.

Each rotor knife has a double-sided comb-shaped profile. This original design provides additional benefits for the operator, offering four cutting edges per stator knife instead of the usual two.

The rotor knife inserts can be rotated around two axes, providing four usable cutting edges per knife.
