Overview of NESTRO® Shredders

NESTRO® shredders convert disposal costs into energy savings while operating quietly. The staggered arrangement of knives ensures low energy consumption, and the slow speed enables silent operation. All wear parts are highly durable and designed for long service life. The shredding capacity depends on the material composition and the screen size.

Key Features and Benefits

• Suitable for various materials
• German technology ensuring absolute reliability and high efficiency
• Robust and mature engineering design
• Easy maintenance

Operating Principle

Material is fed from the top into the hopper. A hydraulically controlled ram pushes the material against the cutting rotor step-by-step, based on the main motor's power consumption. The shredding occurs between rotating knives on the rotor shaft and a fixed counter-knife mounted on the machine frame. The chip size is determined by the perforation size of the screen, which is selected according to the specific application.

Machine Components and Accessories

• Magnetic separator for removing ferrous contaminants
• Hopper enlargement and lid for increased capacity and safety
• Feeder with segmental base plate and spike band for efficient material feeding

Technical Specifications

Power supply: Three-phase current, 400 V, 50 Hz

Critical Information and Recommendations

• Screen hole size must be chosen based on the material and desired chip size
• Hydraulic ram feed rate is controlled by motor load to optimize shredding efficiency
• Robust wear parts extend machine life and reduce downtime
• Quiet operation reduces noise pollution in the working environment
