Heavy-duty industrial shredding machine designed for reliable volume reduction of bulky or difficult materials. It uses four counter-rotating shafts equipped with cutting and clearing discs to grab, shear, and tear materials in a controlled, high-torque, low-speed shredding action


Configuration

Shredder type: Four-shaft / quad-shaft low-speed shredder (2 cutting shafts + 2 clearing/broaching shafts)

Operation: Low shaft speed (~25 rpm) for high torque and quieter operation

Automatic features: Overload protection and automatic reverse on jam/loading

Drive & Motor

Electric motors: Dual motors — typical configurations include 2 × 15 kW up to 2 × 30 kW (~20 – 40 HP each)

Voltage: 460 V / 3 phase / 60 Hz (common in North America)

Gear drive: Planetary gearboxes for high torque

Mechanical Dimensions

Hopper opening (approx): ~1500 mm wide (feed width) (varies by build)

Cutting chamber working width: ~990 mm (39 in)

Rotor (shaft) diameter: ~280 mm (~11 in)

Shaft speed: ~25 rpm (low-speed, high-torque)

Typical overall weight: ~3000 kg (6600 lbs)

Cutting & Throughput

Cutting discs: Hardened cutting discs on each shaft (size and number can vary)

Screened output size: Determined by the screen under the shafts — common diameters 10 – 150 mm depending on screen choice

Throughput: Approx 600 – 1500 kg/h (varies widely by material type and screen)

Features

Heavy-duty construction with reinforced frame and wear plates available

Changeable screens and optional quick-change screen systems

Flexible feed options (hopper, conveyor, forklift, tipping device)

Discharge via suction, conveyor, or screw conveyor

PLC controls often included for operation and automatic reversal
