Pre-Shredder

The Primary Size Reduction Solution for Oversized Materials

Pre-shredders serve as the critical first stage in waste processing systems, specifically engineered to reduce bulky waste into manageable fractions for downstream equipment. These heavy-duty machines combine massive cutting power with robust construction to handle unpredictable material streams while protecting secondary processing equipment.

Engineered for Extreme Duty Applications

The system features a reinforced steel frame construction with 50-100mm thick steel sidewalls that withstand constant impact loads. The cutting mechanism utilizes either single-shaft or twin-shaft configurations with hardened steel cutters capable of processing entire mattresses, pallets, or furniture in a single pass. Hydraulic or electric drive systems deliver 100-500 hp of power for continuous operation under maximum load conditions.

Advanced Cutting Technology

Large-diameter rotors (800-1500mm) with staggered cutting teeth create a tearing and shearing action that efficiently processes mixed material streams. The aggressive cutting geometry combines hook-shaped teeth for material grabbing with chisel points for penetration. Adjustable breaker bars allow output size modification from 300mm down to 100mm depending on downstream requirements.

Operational Features

During operation, the system automatically adjusts feed rates based on motor load to maintain optimal throughput. Integrated metal detection identifies problematic contaminants before they enter the cutting chamber. The slow-speed, high-torque design (10-30 RPM) processes materials with minimal noise and dust generation while preventing wrapping of fibrous materials.

Maintenance for Continuous Production

Daily inspection of cutting components identifies wear patterns requiring attention. Weekly lubrication of all bearings prevents premature failure. Monthly measurement of cutter clearances ensures proper reduction efficiency. The hydraulic system requires quarterly fluid analysis and filter replacement. Advanced models feature automatic tool wear monitoring that predicts maintenance needs.

Application-Specific Configurations

Specialized versions include: grapple-fed systems for demolition waste, tracked mobile units for landfill operations, and explosion-proof designs for hazardous environments. The latest innovations incorporate smart load-sensing that automatically adjusts processing parameters based on material characteristics.
