Disc / Rotor Screen BRT HARTNER SC
You are aiming to sort and separate cardboard and paper in your plant to generate high-quality products at the highest efficiency and lowest costs?
The treatment process in a sorting plant for waste paper is always the same: The paper-cardboard-mix from the municipal collection is first fed to a Feed Hopper. This machine loosens the material and transfers it evenly to further coarse screening. Here, cardboard (approx. larger than a pizza box) is separated. The resulting mixed paper fraction, a mixture of newspapers, magazines, small cardboard, and books, is supplied for further treatment. This treatment includes the separation of the fines within the material, the separation of small cardboard pieces as well as films and foils, and other impurities. The final goal of the separation process is a deinking fraction with a maximum of 3 % impurities.
We have a wide variety of machines and systems under the name of BRT HARTNER to facilitate your plant processes. Our Disc / Rotor Screen BRT HARTNER SC is for example used for the separation of large carboard pieces.
Gear
The Coarse Screen BRT HARTNER SC is equipped with electric gear motors which are driven with chains and sprockets. In addition, it is equipped with rotating rotor elements which each consist of an axle with oval discs. Due to their special rubber mix, the discs have sufficient grip to move the cardboard over the screen to the upper discharge point. However, newspapers, magazines, and other materials of the mixed paper fraction are pulled downwards through the screening discs to a discharge conveyor (to be provided by the customer).
The Coarse Screen is available with two or three screen decks, depending on the requested throughput. The rotational speed of each screen deck can be optimally adjusted via frequency converter as each deck has its own drive motor.
The coarse screening with the Disc / Rotor Screen produces two fractions: one cardboard fraction and one mixed paper fraction.
Disc Screen or Ballistic Separator
In general, cardboard and waste paper can be sorted either with Disc / Rotor Screens or with Ballistic Separators. Both systems work quite differently, however, their results with regard to efficiency and functionality speak for themselves. BRT HARTNER is one of the few manufacturers that specialize in both machines.
