The KRONE OptiMaxx roller conditioners

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.

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.

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 and 305

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
