Due to their high breaking elongation and elastic energy absorption the profiles retain their shape even under mechanical load, are highly flexible and return to their original shape. They also excel with a very high production precision, size accuracy and form stability so that even smaller bar spacings can reliably be maintained.
Another advantage of the RakeMax® Hybrid screen are the individually replaceable screen bars for quick and safe handling without the need for welding work.
Another crucial functional element of a screening system is the profile of the screen bars. To prevent jamming of solids, especially with small bar spacings, and ensure the reliable removal of screenings, the bar rack of the RakeMax®-J is of course also available with the well-proven tear-drop shaped bar profile. The characteristic feature of this profile is a very low headloss. As a result, hydraulic throughput capacity increases compared to conventional flat steel profile or trapezoidal profile bars. This bar shape furthermore prevents jamming of solid material, such as gravel.
The RakeMax® Hybrid screen has proven its functional capability in daily operation and over long operating hours on several sewage treatment plants in Germany and abroad. The RakeMax® Hybrid offers several features which make the screen what is understood as a "modern" technology today.
Yet for all the enthusiasm for the technology, there is one aspect that must not be forgotten: user-friendliness. But also in this respect, it shows impressively how modern machines can be created by adapting individual solutions to the standard and using innovative machine technologies.
