Disc Screen / Rotor Screen BRT HARTNER SF

Does your sorting plant receive mixed fractions of waste paper and cardboard from the municipal collection?

Do 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 for further sorting and subsequently to deinking? Our Disc Screen / Rotor Screen BRT HARTNER SF is the right choice for the 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. 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 a 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.
