    The KRONE OptiMaxx roller conditioners


    166377
    166376
    • OptiMaxxroller conditioners with 250 or 305 mm (9" or 1') diameters
    • Slanted teeth for perfect conditioning to combine with OptiMaize S-XL drums
    • The gap between the rollers is conveniently adjusted from the cab
    • A strong spring assembly provides a consistent and high pressure
    • Maximum fracturing from an up to 50 % speed difference (option)
    Every single kernel must be cracked to achieve an optimal digestibility. These user demands are perfectly met by the new OptiMaxx 250/305 roller conditioners with their slanted teeth, a new KRONE development.
     
    166390

    Perfect conditioning: The new OptiMaxx roller conditioners have their teeth slanted at a 5° angle.This slant produces a clearly higher shearing effect and perfect conditioning of the crop which receives a very intensive treatment both length- and sideways.

     
    166383

    Maximum intensity: The two toothed rollers operate at a 30 % speed difference. This standard difference can now increase to 40-50 % to deliver 100 % conditioning and fracturing of long chops as produced by OptiMaize XL.

    OptiMaxx 250: One for all
    With the new OptiMaxx 250, KRONE presents a roller conditioner that off ers an even higher performance for the BiG X 680, 780, 880, 1180 models. This new development stands out for the following features:
    • 250 mm diameter rollers have slanted teeth that give a unique shearing effect
    • 10 % longer rotors and a 7 % higher rpm over the previous model.The greater length increases the friction surface area and ensures an effective crop intake, intensive conditioning and optimum cracking results
    • Bigger and stronger springsapply a consistently high pressure on the crops
    • The two rollers in the assembly have different numbers of teeth – 105/123 for medium and long chopping lengths – 123/144 for short and medium chopping lengths
    • A standard 30 % speed difference with a 40 % of 50 % differential being an option for intensive fracturing and optimum cracking results

    OptiMaxx 305 – An exclusive for the top model
    The OptiMaxx 305 is a unique feature on our flagship, the BiG X 1180.
    This roller conditioner has a 55mm larger diameter than the OptiMaxx 250 hence matching the gargantuan appetite of this top-end monster machine.
    • 305 mm diameter rollers with oblong teeth give a special shear effect
    • A 11 % larger friction surface area and 20 % higher peripheral speed (than OptiMaxx 250) ensure an exemplary crop intake, intensive conditioning and optimum cracking amid high throughputs and long chop lengths.
    • Stronger and more powerful springs apply a uniform, constant and high pressure on the crops 
    • A redesigned casing with beefier mountings ensures durability and longevity
    • Temperature sensors on the roller bearings transmit the data to the operator terminal and ensure maximum safety
    • Exemplarily easy to service and maintain thanks to large openings.Bearings, rollers and pulleys are replaced quickly and cleaning is as easy.
    • The two rollers in the assembly have different numbers of teeth:
      – 125/150 for medium and long chopping lengths
      – 150/175 for short and medium chopping lengths
    • A standard 30 % speed difference with a 40 % of 50 % differential being an option for intensive fracturing and optimum cracking results
