The HUBER Belt Screen EscaMax® is a system that especially offers our customers excellent separation results. Its high separation efficiency has officially been proven in tests carried out under real conditions with a 6 mm perforation screen. The excellent separation result of 84% has been confirmed by an independent institute.
These above average results are on the one hand due to the two-dimensional design of our well-proven EscaMax® screen. On the other hand, such results can only be achieved on the basis of consequent further development and high manufacturing quality. Another positive aspect as to functionality and reliability is the sturdy design of the EscaMax®, particularly when huge amounts of grit and gravel need to be processed.
Each end of the filter belt of the HUBER EscaMax® screen is connected with a drive chain that is driven by chain wheels. Each chain wheel is driven by a sprocket on a common shaft and a flange mounted gear motor. When they have passed the upper turning point the screening elements are cleaned by an internal spray nozzle bar which operates against screening direction. A separately and continuously driven roller brush enhances the cleaning process additionally. The roller brush operates against the travel direction of the filter belt, this improves cleaning efficiency significantly.
Another advantage of this cleaning method is that a majority of the screenings, including abrasive material, are removed from the screening elements already in the first step of the cleaning process by the spray bar. It is obvious that the wear of both the screening elements and the roller brush is considerably reduced in this way.
Furthermore, we have risen to another technical challenge and developed a new concept for the critical area where the screening elements are cleaned subsequently. The results have exceeded all expectations: The constant spacing between the roller brush and the semicircular screening elements guarantees gentle yet highly effective cleaning, especially with extremely high screenings loads.
