Backers Star
Screen
Technology
Since 1989, Backers has continuously set milestones in star screen technology. Our philosophy is to
offer the customer an effective and economic solution for screening mineral and organic materials, as
well as material mixtures.
The Backers Principle
From our view point, there is one logical
screening process, in order to screen to the
optimum and ensuring clean and efficient
separation. The basic principle for screening
three fractions is: coarse before fine screening.
The coarse grain is separated in the first
screening step (coarse screening) and
discharged. The undersize grain is separated
from coarse grain and oversize tramp material
and then transported to the second screening
step (fine screening). The ascending screening
process enables transfer on plain conveyor
belts, operating at maximum height. Materials
are stockpiles at high drop-off points, of approx.
3000 mm.
The advantages:
• Increase in throughput and enhanced
materials handling
• Good cleaning of the medium grain
• Minimum wear of the screen stars
• Reduction of labour costs and secondary
equipment
Above all, Backers Star Screen machines, manufactured according to a
modular principle, are convincing by their flexibility: Powerful drives, compact
dimensions, various forms of mobility and additional components allow
adaptability for a wide range of materials, with grain sizes (separation size)
of 5 mm up to 80 mm:
• Use in cohesive material is economically possible
• Screening of materials or material mixtures with clay and clay inclusions
(without agglomerates)
• Screening of large-volume materials
• Coarse grain pre-separation is possible; using a tipping grid
