Features and Benefits

  • Three Methods of Reduction: Impact, shear, and compression methods for efficient material reduction.
  • Compact Design: Large mouth for accepting large slabs in a compact structure.
  • Curved Breaker Plates: Ensures proper crushing without allowing large slabs to pass through.
  • Low Profile: Fits easily in limited spaces and under dump hoppers.
  • Superior Roll Assembly: Teeth securely fixed, minimizing loosening.
  • Minimal Fines Production: Fractures material along natural lines, reducing fines.
  • No Screen Bars: Prevents re-crushing, further reducing fines.
  • Low Power Requirement: Operates at low speeds, minimizing power demand.
  • Multiple Models: Cater to varying material strengths and applications.
  • Accurate Size Reduction: Effective for materials with moderate to high compression strength.
  • Open Bottom Discharge: Allows sized material to fall through without re-crushing.
  • Product Size Control: Gap adjustment for precise output size control.
  • Easy Adjustment: Shim arrangement for quick output size adjustments.
  • Flexible Feeding Options: Choke-fed or continuous from various equipment.
  • Efficient Material Reduction: Impact, shear, and compression ensure effective reduction.
  • Space-saving Design: Fits well in limited spaces.
  • Reduced Fines Production: Minimizes fines for better material quality.
  • Energy Efficiency: Low-speed operation leads to cost savings.
  • Versatile Application: Suitable for a range of materials.
  • Controlled Output Size: Easy adjustment for precise output control.
  • No Material Recirculation: Maintains product integrity with open bottom discharge.
  • Reliable Performance: Secure assembly for consistent operation.
  • Ease of Maintenance: Simple adjustments and robust design for easy maintenance.
  • Flexibility in Feeding: Integrates seamlessly with various feeding systems.
