Finally straight to the point:

Characteristics influencing regrind quality

  • Gentle angled cutting avoids burden at peak loads, guarantees a high value regrind that is not thermally degraded and that is distinguished by sharp edges, high homogeneity and low level of dust.
  • Optimum speed range of the machines according to the size and purpose, thereby optimum speed range for low energy consumption, low level of dust and quiet operation.
  • Sieves with sieve hole diameters from 5-30 mm, designed to prevent formation of long, thin regrind,  large sieve area enables high throughput and low level of dust as a result of fast material delivery, special sieves.
  • High throughput at low drive power

 

Engineering, design characteristics

  • Stiff, non-twisting rotors produced from one solid piece of metal, no imbalance.
  • Double-sided exterior rotor bearings, no penetration of dust and therefore longer bearing life, no contamination of the ground material by lubricant.
  • Knives in high quality knife-grade steel, high durability.
  • Constant cutting gap over the entire knife width, so optimum specific energy consumption.
  • Noise absorbent hoppers, off-centre insertion guarantees self-dosing feeding behaviour, no dancing and hurling out of material.
  • Compact design, less need for space.
  • Wear resistant versions for reinforced plastics.
  • Extensive consideration of safety measures regarding risks according to the equipment safety law

 

Operation, maintenance, cleaning

  • Opening of the granulators without tools, enabling fast cleaning with changes of colour and material, faster sieve and knife replacement.
  • Structural design for easy, complete cleaning through absence of dead corners.
  • Direct mounting of the knives on solid rotors, eliminating need for rotor knife adjustment.
  • Both rotor and stator knives can be re-sharpened many times due to their structural design.
  • Start-up of the machines with filled grinding chambers ensured under normal operation conditions
