  Superrotor
Sifter
The patented SuperRotor Sifter from PTN
provides high efficiency separation by all kind of screening
applications. Depending on purpose, the sifter is available in 3
variaties. With its very low height the SuperRotor Sifter can be fitted
in existing as well as new plants.
As the screening system provides a compact, fast,
efficient and accurate method of size separation it is usable for
screening in connection with pelleting, raw materials, bulk delivery and
as structure/prescreening system at the grinding system.
Product description:
The sifter is built of two units. A square welded
vibration housing with 4 dampers for direct 4 points mounting, equipped
with the sifterunit. Direct on the housing foundation for mainmotors
there has been mounted motors for the rotation speed as well as the
vibrating movements.
The round screeningsystem with central inlet is built
in the cylindric sifterhouse. The product leaves the sifter through the
conical central outlet. The sifterhouse is fitted to the housing by 4
bolts.
As product encounters the screening surface
centrifugal force from the rotating screen softly moves the product
across the vibrating screening surface.
The variable speed motor controls the rotation of the
screen which in turn controls the speed that the product is travelling
across the screening surface. A constant speed motor provides the
vibrating motion. The small particles and fines passing through the
screenmesh are removed by the fines drag system rotating with and below
the screening surface.
