Coarse screening screen BRT HARTNER SC

The treatment process in a sorting plant for waste paper is always the same: The paper-cardboard-mix from municipal collection is first fed to a Feed Hopper. This machine loosens up the material and evenly transfers it to subsequent 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 to 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. Drive 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 consists 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 material of the mixed paper fraction are pulled downwards through the screening discs to a discharge conveyor (to be provided by the customer).
