Finedoor have just completed an agreement to distribute and manufacture The ORTNER in the UK and Eire.
 
The ORTNER is a revolutionary concept from the USA for dewatering, removing fines, classifying and rinsing sand and other materials up to 60mm and has the performance capabilities and advantages unmatched by other machinery. It is currently used by the majority of the major aggregate producers in the USA.

The ORTNER can also wash fine and course material up to 75mm providing the flexibility to produce many varied products with one machine. Dry material may be fed to the ORTNER to remove excess fines or rinse coarse material by adding a small quantity of water.
When fed wet slurry, as from a density separator or a hydrocyclone, the ORTNER may be used to dewater the product. It may also be used to remove excess fines from the slurry or it may classify the slurry.

The operation and principle are simple as the material is fed to a slowly revolving pan on an incline which is vibrated at high speed. The high speed vibration quickly separates the various sizes of material with the fines and water rising to the top and flowing over the weir to the discharge. With the coarser particles sinking to the bottom the rotating pan carries the settled particles up the machine and out of the water, where a stationary plough diverts the dewatered material to a centre discharge chute. The driving and vibrating mechanism is mounted under the pan, preventing any contamination with the water and processed material, thus increasing the life of the components.
It is possible to vary the angle, speed, and vibrations of the pan. This gives the ORTNER a wide range of flexibility and increases its capacity and efficiency.

The ORTNER is available as a static or mobile machine to fit existing or new process.
