A round barrel with replaceable Hardox lining in which at the bottom a chain rotates at approximately 700 rpm. The chain breaks, opens and strikes, like a mixer, material upwards that collides with falling material and provides extra separation and breakage. The reduced material leaves the machine via a slide in the side wall. Because of the many variable settings many possibilities for different fractions. Numerous unique applications: Electronics scrap / WEEE, Refrigerators, Aluminum connections, Plastic - Metal connections, Rotations, Magnet fractions, Catalysts, Scrap fractions, Polyester fractions, Others.. Variable settings: one tool for many different purposes | RPM of chain by frequency converter | Residence time in the machine Sliding opening | All settings programmable | Different impact tools Replaceable Hardox walls and floor | Good access during maintenance | Easy change chain
