At the bottom of the prill tower a Kreber design scraper is applied to collect the prills. The design is such that the freshly formed prills are treated gently. No less than zero rejected prills is the goal of our design team. Our scrapers are available in two standard configurations; horizontal and conical. The Kreber scraper features:

  • Simple maintenance and low operational expenses
  • Sufficient redundancy to cope with emergency situations
  • Soft drive behaviour in start, stop or overload situations
  • High torque transmissions that eliminate pulses in prill transportation
  • All drive parts under the prill floor, shielded from the prilled product
  • Wear resistant, adjustable scraper blades
  • Horizontal or conical executions up to tower diameters of 32 meters
