This single-shaft, with circular knives, hydraulic pusher and calibration grid type shredder has been designed to shred and refine the most diverse products, wood, metal, plastics, plastic purges, electric cables, electronics cards...
Once the product has been introduced into the hopper, the hydraulic pusher forces the shredding on the knives of the rotating rotor while a counter-knife prevents the product to wrap around the rotor. An automatic ejection mechanism of foreign objects (not crushable) allows to avoid damage to the calibration grid or the counter knife.
The calibration grid, easily interchangeable and cleanable, does not allow the exit of the product until it reaches the size of exit required. The knives are circular, interchangeable, and sharpenable. They are mounted on a hexagonal shaft. This solution allows in case of damage or wear extreme to change a knife without having to change the entire rotor.
