BRT HARTNER Disc Screen for the cleaning of mixed paper

Disc Screen / Rotor Screen BRT HARTNER SF

Fine Screen for the Cleaning of Mixed Paper and the Pretreatment of Deinking Material

Your sorting plant receives mixed fractions of waste paper and cardboard from municipal collection? You want these fractions to be separated and prepared for manual, mechanical or optical sorting? The oversize fraction from the screening process is to be supplied to further sorting and subsequently to deinking? Our Disc Screen / Rotor Screen BRT HARTNER SF is the right choice for highest quality screening of mixed paper at an excellent cost-benefit ratio.

Suitable machines for the professional cleaning and separation of high quantities of cardboard-wastepaper-mixes are either Disc Screens / Rotor Screens or Ballistic Separators. Even though they are very different from each other, both systems have their justification and are equally effective and functional. The Eggersmann GmbH is one of the few companies that has both machine types in their product range under the brand of BRT HARTNER.

The Disc Screen / Rotor Screen BRT HARTNER SF has rotating rotor elements which consist of axles with oval discs. It is driven by an electrical gear motor with chains and sprockets. The up and down movement of the discs sets the material into a kind of “swimming” movement.

The SF Fine Screen moves the material to the upper discharge point with small steel discs. In addition, it is equipped with two or three screening decks, depending on the requested throughput performance. Each deck is fitted with its own drive motor. The decks are arranged in cascades, so the material is turned over at least once. Furthermore, the rotational speed of each deck can be optimally adjusted via frequency converter. The newspapers and magazines are separated and moved over the decks. Small disruptive elements like cigarette packets, scraps of paper, crown corks, bottle caps and other similar fine parts are cleaned out, separated and discharged through the screen discs to a hopper underneath the screening machine.

The SF Fine Screen by BRT HARTNER creates two fractions: one clean mixed paper fraction suitable for further treatment and one fine fraction.


  • Efficient cleaning and separation of the mixed paper by Disc Screens / Rotor Screens
  • Cost-effective and durable
  • Impervious to disruptive material
  • Loosened up and even material feeding to subsequent sorting 
  • Easy integration into existing plants due to its small dimensions
  • Simple exchange/replacement of individual rotor elements 
  • Dynamic adjustment of the screen cut size
  • Easy cleaning due to special axle shape
  • Optionally with frequency-controlled speed adjustment
  • Slow-runner
