Ballistic Separators are the best alternative in comparison to disc screens or rotor screens. They are nearly entanglement-free as well as maintenance-friendly and flexible in use. The Ballistic Separator separates the material into two fractions. The waste paper falls through the openings of the paddles. Subject to its climbing ability cardboard travels upward, to the overflow at the upper end of the machine. The vertical acceleration mixes the material thoroughly which leads to good separation with a high separation quality. The construction with several screening decks in a row supports the efficiency.
