The dramatic difference between the C&D/asphalt rating (up to 175 tph) and the mixed waste rating (up to 19 tph) reflects how differently these materials behave under slow-speed dual-shaft shredding. C&D material — concrete, asphalt, brick, block, and rubble — is dense and brittle. Under the Krokodile’s counter-rotating shafts and cutting teeth, it fractures quickly and passes through the machine efficiently at very high tonnage. The energy per ton is high, but the material moves fast.

Mixed waste and plastics are a different challenge. These materials are lighter, more flexible, and tend to wrap, tangle, or resist cutting rather than fracture. The shredder must work harder per unit of material to produce consistent output, which reduces throughput and increases the time per ton. The Krokodile’s synchronized and asynchronized shaft modes help manage wrapping and difficult material by reversing and varying shaft speed to clear jams without manual intervention — but the physics of shredding flexible material simply require more time than brittle material.
