Since the end of June medical bags with physiologic salt solution and other filled plastic bottles are shredded with a bomatic rotor shear B850VD. What is special about this machine is that the spill is separated with a custom-built dewatering auger through a perforated strainer, the solid fraction is transported to a press container for compacting. "The high amount of liquid meant a challenge for us", explains Marion Böttcher, technical director at bomatic. Per hour incur at least up to 8 tons of liquid, that goes through the cutting unit. The bomatic-experts met the challenge by using a sealed cutting unit with external spherical roller bearings. Radial shaft sealing rings and labyrinth seals protect the mounting, liquids are prevented to get in the machine's core.
