The first ORTNER off the production line at Finedoor has now been delivered to Tom Doyle Aggregates in Ireland.

The ORTNER is a well proven concept 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 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 a 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.

Now fully commissioned the machine is proving its capabilities.............more news on production rates soon.
