GRANULATORS – DESIGN & CONSTRUCTION

Over-engineered for maximum performance and many years of trouble-free operation

  • Tangential feed design assures positive feeding of the material (PIC. A), maximizes throughput, reduces fines and helps prevent jamming. Non tangential feed, stainless steel, abrasion resistant and water-cooled cutting chambers are also available.
  • Quick and easy access to the cutting chamber – for cleaning or blade changes (PIC. B). This design, developed by ROTOGRAN, has now become an industry-wide standard.
  • Swing-down, heavy duty removable screen cradle provides improved access to the cutting chamber.
  • Hydraulic operation (PIC. C) is standard on larger models.
  • All cutting chambers are fabricated from certified ground steel plate as a heavy duty one piece weldment that is rigid, smooth and easy to clean.
  • Improved “electrical – mechanical” lock-out feature (PIC. D) ensures safety on the plant floor.
  • Chamber is solidly welded on a sound insulated frame and supported on machinery pads. Standard chamber sizes range from 8” x 8” to 44” x 72”.
  • Solid-steel flywheels minimize motor and rotor abuse, reduce horsepower requirements and electrical power costs (PIC. E).
  • Open rotor design provides a cooler operation and increased throughput.
  • Offset rotor for minimum fly-back and positive cutting action.
  • Scissor cutting action assures positive granulating with minimum of fines resulting in lower power consumption.
  • Heavy-duty, 4140 steel rotors are available in 3, 5, 7 and 9 blade configurations. Water-cooled and alternate rotor designs are available on request.
  • ROTOGRAN blades are made from fully-hardened and precision ground D2 certified tool steel.
  • Micro adjustable bed blades are easily accessible from the front of the granulator.
  • Acoustically insulated sound absorbing panels are a standard feature on all ROTOGRAN granulators. Additional sound enclosures are available as requested.
