the sieve frame has been optimized. The
“Backers Premium Star Screen” system
works on the basis of classical square
shafts, but also with a new drive and a
change system.
In addition the Backers company
offers the new Premium Star Screen also
as “High-Performance Screen”. In this
case spring steel inlets are vulcanized in
the star spikes. The spaces between the
star discs are cleaned even better, they
are continuously cleaned by a scraper.
The spring steel scrapers are inserted
into the elastic spikes and cannot be
deformed or broken. These stars also
convince during screening of material
which is difficult to screen.
These stars also have a long operating
life when screening earth with stones.
Now a smaller sieve cut is possible
while screening cohesive soil, sludge,
etc. Through the scrapers the screening
waves run easier, which reduces the
driving force. This results in higher
screening performance, longer operating
life, lower fuel consumption.
